+
+Small cosmetic changes. Cleaning up the contributions.
+New makefile for mingw32, and new fbcon example.
+Major thanks to Greg for helping out with the *nix stuff!
+Note that there's also a separate download for ASM programmers now.

+
+Maintenance release.
+Fixed several memory-leaks with the help of Gregg Kelly, added/fixed some CMS
+handling, exported JPEG functions from standard DLL, and some other minor fixes.

+
+1.0.0 (Feb 6th 2001)
+--------------------
+
+in short:
+
+First public release. Finally(!)
+
+This is the 0.9.5 CVS version, which will never be released, because I feel it
+is now ready for a public release. So apart from the version-numbers here and
+there, all other changes are listed under 0.9.5.
+
+This library will work with every MNG/JNG known and available to me. Note that
+there are still parts that need to be coded, and that MNG support is around
+90-95% (JNG at 100%). It is however compliant with the latest and greatest
+MNG 1.0 specification.
+
+I hope to dedicate a bit more time this year to finish up full support and fill
+in the remaining blanks. But this is coming out of my spare time. And extra
+help is always appreciated.
+
+Please enjoy!
+
+Gerard

+
+in short:
+
+Now that the MNG spec is at 1.0, this should be the last beta. There's a few
+small changes to make it inline with the spec, and a couple of bug-fixes.

+in short:

+going to be another beta-round. If things go well, I'm going to try to release
+libmng 1.0.0 very shortly after this one.
+
+Many thanks to a lot of people for helping out, sending contributions, making
+suggestions and testing this little baby. This would get nowhere without YOU!!!

+
+Thanks to all the people who helped to guide me in the right direction.

+Configuration from CVS
+======================
+
+If you're using source checked out from CVS, rather than a source
+distribution tarball, please be aware that you can use ./autogen.sh in
+place of ./configure below.
+
+Because this is a cross-platform project, the source templates for
+the autoconf scripts are sequestered in the 'makefiles' directory.
+Running './autogen.sh' will copy them into their conventional places at
+the lop level. If you already see the files there, you don't need to
+worry about this step.
+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems retquire unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--tquiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+Configuration options in libmng
+===============================
+
+The library is fairly configurable through the use of a number of defines.
+Please note however that certain defines are for internal use only.
+The following list gives a summary of options that can be used externally to
+define the functionality of the library:
+
+========================================
+
+#define MNG_BUILD_DLL
+
+This is used to indicate that a "standard" DLL should result from compiling
+the library. Please note the remarks in README.dll if you intend to work
+with the library as a DLL. The purpose of this option is to ensure that
+DLL builds have the same set of functions.
+
+#define MNG_BUILD_SO
+
+This is used to indicate that a "standard" shared library (SO) should result
+from a compilation. The purpose of this option is to ensure that all
+shared libraries generated this way will have the same set of functions.
+
+#define MNG_USE_DLL / #define MNG_USE_SO
+
+These should be used when including the library header in the compilation
+of an application to indicate that the compiler/linker must take the
+necessary steps to make the binary executable to use the standard DLL
+or shared library (SO).
+
+#define MNG_SKIP_ZLIB / #define MNG_SKIP_LCMS / #define MNG_SKIP_IJG6B
+
+Use these in conjunction with MNG_USE_DLL / MNG_USE_SO. This is useful if
+you only need the external definitions of the MNG library and not the others,
+which will speed up the compilation process.
+
+#define MNG_SUPPORT_FULL / #define MNG_SUPPORT_LC / #define MNG_SUPPORT_VLC
+
+These can be used to indicate the level of MNG spec compliance retquired.
+Currently only full MNG compliance is supported.
+
+#define MNG_SUPPORT_IJG6B
+
+This can be used to indicate if JNG support is retquired. This option will
+include the IJG JPEG-library. Note that MNG_SUPPORT_FULL will automatically
+set this option. Use this only if you need JNG support with MNG-(V)LC.
+
+#define MNG_FULL_CMS / #define MNG_GAMMA_ONLY / #define MNG_NO_CMS /
+#define MNG_APP_CMS
+
+These indicate the color-correction support level of the library.
+If you are on a platform that supports lcms (Little CMS by Marti Maria Saguar)
+then it is highly recommended to define MNG_FULL_CMS.
+If your platform has it's own CMS then select MNG_APP_CMS and be sure to
+include the appropriate callbacks in your app.
+In all other cases it is recommended to define MNG_GAMMA_ONLY.
+
+#define MNG_SUPPORT_READ / #define MNG_SUPPORT_WRITE /
+#define MNG_SUPPORT_DISPLAY
+
+These indicate the high-level support for reading, writing and/or
+displaying files. Note that in order to display a file, you'll need to read
+it first. (yes, really!)
+
+#define MNG_STORE_CHUNKS
+
+This indicates that the library should store chunk-information when reading
+a file. This information can then be processed through the
+MNG_ITERATE_CHUNKS() function. Note that you must specify this option if
+you want to create and write a new file.
+
+#define MNG_ACCESS_CHUNKS
+
+This is used to indicate that the app may need access to internally stored
+chunk information. MNG_STORE_CHUNKS must be defined as well for this option
+to function properly.
+
+#define MNG_INTERNAL_MEMMNGMT
+
+You can use this to have the library handle it's own memory allocation and
+deallocation through the "standard" memory functions. This option is turned
+off by default, which means your app must define the memory callbacks.
+
+#define MNG_ERROR_TELLTALE
+
+Set this on to allow human-readable error-messages to be included in the
+library and the error function and callback.
+
+#define MNG_BIGENDIAN_SUPPORTED
+
+This option should be used to indicate the hardware is based on big endian
+integers.
+
+#define MNG_SUPPORT_TRACE / #define MNG_TRACE_TELLTALE
+
+These two can be used when debugging an app. You'll need to have the trace
+callback setup also. This allows for a rather thorough investigation of the
+libraries function paths.
+
+========================================
+
+Any other optional defines you may encounter are for internal use only.
+please do not specify them externally. In case of doubt, consult the
+support email lists. More info can be found on http://www.libmng.com

+Standard Windows DLL
+====================
+
+The DLL provided in the BCB/win32dll directory is meant as the sole candidate
+for distributions, based on libmng.dll, that install the DLL into the public
+Windows system-directory. The outline herein defines the retquirements to
+which such a distribution must comply. If you cannot comply with these
+retquirements please install the dll in the same directory as your application
+and NOT in the Windows system-directory!!!
+
+
+1) Only the DLL already assembled in the libmng distribution may be used for
+ other distributions!
+
+2) Only stable public releases are eligible for distribution! A public release
+ is one where the y-value of the x.y.z version-code is an even number.
+ Eg. 1.0.0, 1.2.1, 2.4.7, etc.
+
+3) The installation program MUST store the DLL in the Windows system-directory!
+ Eg. C:\WinNT\System32, C:\Windows98\System
+ (Note: InstallShield users can use the <SYSDIR> variable)
+
+3) The installation program MUST flag the file as a shared library!
+
+4) The installation program MUST NOT install the DLL if a newer version
+ already exists in the Windows system-directory! The standard DLL provided
+ contains the Windows-default version-numbering system. PLEASE USE IT!!
+ DO NOT rely on the date or size of the files.
+
+5) An uninstall procedure MAY NOT remove the DLL if other applications are
+ still linked to it! Proper handling as a shared library is imperitive.
+
+6) TEST IT, TEST IT, TEST IT!!! (I just can't stress this enough)
+ If you don't have enough time, let someone else test it BEFORE you
+ distribute!
+
+
+The penalty for violating these rules is inclusion of your name in the list
+of endangered but useless species (just below the GIF entry!), and on my
+blacklist. YOU HAVE BEEN FOREWARNED!

+ IJG jpgsrc6b and lcms1.0.6. The directories containing these
+ libraries must be at the same level as the libmng directory.
+ So if you're in the directory with this file and the libmng
+ sources, they should be in ..\zlib , ..\jpgsrc6b and ..\lcms
+ respectively.
+
+!!! To run the other Win32 samples you need to copy the libmng.dll
+ file from here into the sample's directory !!!
+
+mngtree - sample project to create a little command-line tool that dumps
+ the chunk-structure of a given file onto stdout.
+
+bogus - a completely bogus example on how to create a perfectly valid
+ (though slightly biased) MNG.
+
+mngview - port of the Delphi mngview sample. contributed by Andy Protano.
+ see also README.contrib
+
+
+delphi - Borland Delphi (3.0+)
+------------------------------
+
+mngview - sample project for a simple mng-viewer. The general unit in
+ the delphi directory was translated from libmng.h It can be
+ used in other projects to access libmng.dll created with the
+ win32dll example above.
+
+
+unix - Unix
+-----------
+
+mngtree - basically a copy of the BCB sample. It includes a makefile for
+ Linux and it's been tested on RedHat6.2

+Packaging Libmng for distribution
+---------------------------------
+
+These are some notes for those building binaries for distribution.
+
+We're interested to hear about anywhere libmng is helpful, so let us
+know if you're including it with your application or OS. Also, if your
+build is publicly accessible, we'd be happy to link to it from
+the libmng site.
+
+However, We respectfully request that you *not* distribute binaries as a
+shared library (DLL) with any of the major features disabled. While
+there is support for this in terms of #ifdef directives (in
+libmng_conf.h) and autoconf switches they are intended for embedded
+application and testing. The default compilation options support the
+full MNG specification, and we wish to avoid the confusion among
+general users that partial support would engender.
+
+
+Platform specific notes:
+
+We have a basic .spec file for generating rpms. Send us a note if you'd
+like to clean it up.

+libmng - Multiple-image Network Graphics (MNG) Reference Library 1.0.4
+
+DESCRIPTION
+The libmng library supports decoding, displaying, encoding, and various
+other manipulations of the Multiple-image Network Graphics (MNG) format
+image files. It uses the zlib compression library, and optionally the
+JPEG library by the Independant JPEG Group (IJG) and/or
+lcms (little cms), a color-management library by Marti Maria Saguer.
+
+
+I. Introduction
+
+This file describes how to use and modify the MNG reference library
+(known as libmng) for your own use. There are seven sections to this
+file: introduction, callbacks, housekeeping, reading, displaying,
+writing, and modification and configuration notes for various special
+platforms. We assume that libmng is already installed; see the
+INSTALL.README file for instructions on how to install libmng.
+
+Libmng was written to support and promote the MNG specification.
+
+The latest MNG specification (currently 1.0) is available at
+ http://www.libpng.org/pub/mng
+
+Other information about MNG can be found at the MNG home page at
+ http://www.libpng.org/pub/mng
+
+The latest version of libmng can be found at its own homepage at
+ http://www.libmng.com
+
+In most cases the library will not need to be changed.
+For standardization purposes the library contains both a Windows DLL
+and a makefile for building a shared library (SO). The library is
+written in C, but an interface for Borland Delphi is also available.
+
+Libmng has been designed to handle multiple sessions at one time,
+to be easily modifiable, to be portable to the vast majority of
+machines (ANSI, K&R, 32-, and 64-bit) available, and to be easy
+to use.
+
+Libmng uses zlib for its compression and decompression of MNG files.
+Further information about zlib, and the latest version of zlib, can be
+found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
+The zlib compression utility is a general purpose utility that is
+useful for more than MNG/PNG files, and can be used without libmng.
+See the documentation delivered with zlib for more details.
+
+Libmng optionally uses the JPEG library by the Independant JPEG Group
+(IJG). This library is used for the JNG sub-format, which is part of
+the MNG specification, and allows for inclusion of JPEG decoded and
+thus highly compressed (photographic) images.
+Further information about the IJG JPEG library and the latest sources
+can be found at <http://www.ijg.org>.
+
+Libmng can also optionally use the lcms (little CMS) library by
+Marti Maria Saguer. This library provides an excellent color-management
+system (CMS), which gives libmng the ability to provide full
+color-correction for images with the proper color-information encoded.
+Further information and the latest sources can be found at
+<http://www.littlecms.com/>.
+
+Libmng is thread safe, provided the threads are using different
+handles as returned by the initialization call.
+Each thread should have its own handle and thus its own image.
+Libmng does not protect itself against two threads using the
+same instance of a handle.
+
+The libmng.h header file is the single reference needed for programming
+with libmng:
+
+#include <libmng.h>
+
+
+II. Callbacks
+
+Libmng makes extensive use of callback functions. This is meant to
+keep the library as platform-independant and flexible as possible.
+Actually, the first call you will make to the library, already contains
+three parameters you can use to provide callback entry-points.
+
+Most functions must return a mng_bool (boolean). Returning MNG_FALSE
+indicates the library the callback failed in some way and the library
+will immediately return from whatever it was doing back to the
+application. Returning MNG_TRUE indicates there were no problems and
+processing can continue.
+
+Let's step through each of the possible callbacks. The sections on
+reading, displaying and writing will also explain which callbacks are
+needed when and where.
+
+- mng_ptr mng_memalloc (mng_size_t iLen)
+
+A very basic function which the library uses to allocate a memory-block
+with the given size. A typical implementation would be:
+
+ mng_ptr my_alloc (mng_size_t iLen) {
+ return calloc (1, iSize);
+ }
+
+Note that the library retquires you to zero-out the memory-block!!!
+
+- void mng_memfree (mng_ptr pPtr,
+ mng_size_t iLen)
+
+Counterpart of the previous function. Typically:
+
+ void my_free (mng_ptr pPtr, mng_size_t iLen) {
+ free (pPtr);
+ }
+
+- mng_bool mng_openstream (mng_handle hHandle)
+- mng_bool mng_closestream (mng_handle hHandle)
+
+These are called by the library just before it starts to process
+(either read or write) a file and just after the processing stops.
+This is the recommended place to do I/O initialization & finalization.
+Whether you do or not, is up to you. The library does not put any
+meaning into the calls. They are simply provided for your convenience.
+
+- mng_bool mng_readdata (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pRead)
+
+This function is called when the library needs some more input while
+reading an image. The reading process supports two modes:
+Suspension-mode (SMOD) and non-suspension-mode (NSMOD).
+See mng_set_suspensionmode() for a more detailed description.
+
+In NSMOD, the library retquires you to return exactly the amount of bytes
+requested (= iBuflen). Any lesser amount indicates the input file
+is exhausted and the library will return a MNG_UNEXPECTEDEOF errorcode.
+
+In SMOD, you may return a smaller amount of bytes than requested.
+This tells the library it should temporarily wait for more input to
+arrive. The lib will return with MNG_NEEDMOREDATA, and will expect a
+call to mng_read_resume() or mng_display_resume() next, as soon as
+more input-data has arrived.
+
+For NSMOD this function could be as simple as:
+
+ mng_bool my_read (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pRead) {
+ *pRead = fread (pBuf, 1, iBuflen, myfile);
+ return MNG_TRUE;
+ }
+
+- mng_bool mng_writedata (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pWritten)
+
+This function is called during the mng_write() function to actually
+output data to the file. There is no suspension-mode during write,
+so the application must return the exact number of bytes the library
+requests to be written.
+
+A typical implementation could be:
+
+ mng_bool my_write (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pWritten) {
+ *pWritten = fwrite (pBuf, 1, iBuflen, myfile);
+ return MNG_TRUE;
+ }
+
+- mng_bool mng_errorproc (mng_handle hHandle,
+ mng_int32 iErrorcode,
+ mng_int8 iSeverity,
+ mng_chunkid iChunkname,
+ mng_uint32 iChunkseq,
+ mng_int32 iExtra1,
+ mng_int32 iExtra2,
+ mng_pchar zErrortext)
+
+This function is called whenever an error is detected inside the
+library. This may be caused by invalid input, callbacks indicating
+failure, or wrongfully calling functions out of place.
+
+If you do not provide this callback the library will still return
+an errorcode from the called function, and the mng_getlasterror()
+function can be used to retrieve the other parameters.
+
+This function is currently only provided for convenience, but may
+at some point be used to indicate certain errors may be acceptable,
+and processing should continue.
+
+- mng_bool mng_traceproc (mng_handle hHandle,
+ mng_int32 iFuncnr,
+ mng_int32 iFuncseq,
+ mng_pchar zFuncname)
+
+This function is provided to allow a functional analysis of the
+library. This may be useful if you encounter certain errors and
+cannot determine what the problem is.
+
+Almost all functions inside the library will activate this
+callback with an appropriate function-name at the start and end
+of the function. Please note that large images may generate an
+enormous amount of calls.
+
+- mng_bool mng_processheader (mng_handle hHandle,
+ mng_uint32 iWidth,
+ mng_uint32 iHeight)
+
+This function is called once the header information of an input-
+image has been processed. At this point the image dimensions are
+available and also some other properties depending on the type
+of the image. Eg. for a MNG the frame-/layercount, playtime &
+simplicity fields are known.
+
+The primary purpose of this callback is to inform the application
+of the size of the image, and for the application to initialize
+the drawing canvas to be used by the library. This is also a good
+point to set the canvas-style. Eg. mng_set_canvasstyle().
+
+- mng_bool mng_processtext (mng_handle hHandle,
+ mng_uint8 iType,
+ mng_pchar zKeyword,
+ mng_pchar zText,
+ mng_pchar zLanguage,
+ mng_pchar zTranslation)
+
+This callback is activated for each textual chunk in the input-
+image. These are tEXt, zTXt & iTXt. It may be used to retain
+specific comments for presentation to the user.
+
+- mng_bool mng_processsave (mng_handle hHandle)
+- mng_bool mng_processseek (mng_handle hHandle,
+ mng_pchar zName)
+
+The purpose of these callbacks is to signal the processing of the
+SAVE & SEEK chunks in a MNG input-file. This may be used in the
+future to specify some special processing. At the moment these
+functions are only provided as a signal.
+
+- mng_ptr mng_getcanvasline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+- mng_ptr mng_getbkgdline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+- mng_ptr mng_getalphaline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+
+These callbacks are used to access the drawing canvas, background
+canvas and an optional separate alpha-channel canvas. The latter is
+used only with the MNG_CANVAS_RGB8_A8 canvas-style.
+
+If the getbkgdline() callback is not supplied the library will
+composite full or partially transparent pixels in the image against
+a specified background color. See mng_set_bgcolor() for more details.
+If a chosen canvas-style includes an alpha-channel, this callback
+is very likely not needed.
+
+The application is responsible for returning a pointer to a line of
+pixels, which should be in the exact format as defined by the call
+to mng_set_canvasstyle() and mng_set_bkgdstyle(), without gaps between
+the representation of each pixel.
+
+- mng_bool mng_refresh (mng_handle hHandle,
+ mng_uint32 iX,
+ mng_uint32 iY,
+ mng_uint32 iWidth,
+ mng_uint32 iHeight)
+
+This callback is called when the library has drawn a complete frame
+onto the drawing canvas, and it is ready to be displayed.
+The application is responsible for transferring the drawing canvas
+from memory onto the actual output device.
+
+- mng_uint32 mng_gettickcount (mng_handle hHandle)
+
+This function should return the number of milliseconds on some internal
+clock. The entire animation timing depends heavily on this function,
+1and the number returned should be as accurate as possible.
+
+- mng_bool mng_settimer (mng_handle hHandle,
+ mng_uint32 iMsecs)
+
+This callback is activated every time the library retquires a "pause".
+Note that the function itself should NOT execute the wait. It should
+simply store the time-field and allow the library to return. Libmng
+will return with the MNG_NEEDTIMERWAIT code, indicating the callback
+was called and it is now time to execute the pause.
+
+After the indicated number of milliseconds have elapsed, the application
+should call mng_display_resume(), to resume the animation as planned.
+
+This method allows for both a real timer or a simple wait command in the
+application. Whichever method you select, both the gettickcount() and
+settimer() callbacks are crucial for proper animation timing.
+
+- mng_bool mng_processgamma (mng_handle hHandle,
+ mng_uint32 iGamma)
+- mng_bool mng_processchroma (mng_handle hHandle,
+ mng_uint32 iWhitepointx,
+ mng_uint32 iWhitepointy,
+ mng_uint32 iRedx,
+ mng_uint32 iRedy,
+ mng_uint32 iGreenx,
+ mng_uint32 iGreeny,
+ mng_uint32 iBluex,
+ mng_uint32 iBluey)
+- mng_bool mng_processsrgb (mng_handle hHandle,
+ mng_uint8 iRenderingintent)
+- mng_bool mng_processiccp (mng_handle hHandle,
+ mng_uint32 iProfilesize,
+ mng_ptr pProfile)
+- mng_bool mng_processarow (mng_handle hHandle,
+ mng_uint32 iRowsamples,
+ mng_bool bIsRGBA16,
+ mng_ptr pRow)
+
+These callbacks are only retquired when you selected the MNG_APP_CMS
+directive during compilation of the library. See the configuration
+section for more details.
+
+- mng_bool mng_iteratechunk (mng_handle hHandle,
+ mng_handle hChunk,
+ mng_chunkid iChunkid,
+ mng_uint32 iChunkseq)
+
+This callback is only used for the mng_iterate_chunks() function.
+It is called exactly once for each chunk stored.
+
+
+III. Housekeeping
+
+
+> Memory management
+
+The library can use internal memory allocation/deallocation or use
+provided callbacks for its memory management. The choice is made at
+compilation time. See the section on customization for details.
+
+If internal management has been selected, the memory callback functions
+need not be supplied. Even if you do supply them they will not be used.
+The actual code used is similar to the code discussed in the callback
+section:
+
+ pPtr = calloc (1, iSize);
+
+ free (pPtr);
+
+If your compiler does not support these functions, or you wish to monitor
+the library's use of memory for certain reasons, you can choose to
+compile the library with external memory management. In this case the
+memory callback functions MUST be supplied, and should function as if the
+above code was used.
+
+
+> Initialization
+
+The basic initialization of the library is short and swift:
+
+ myhandle = mng_initialize (myuserdata, my_alloc,
+ my_free, MNG_NULL);
+ if (myhandle == MNG_NULL)
+ /* process error */;
+
+The first field is an application-only parameter. It is saved in
+libmng's internal structures and available at all times through the
+mng_get_userdata() function. This is especially handy in callback functions
+if your program may be handling multiple files at the same time.
+
+The second and third field supply the library with the memory callback
+1function entry-points. These are described in more detail in the callback
+section and the previous paragraph.
+
+The fourth and last field may be used to supply the library with the
+entry-point of a trace callback function. For regular use you will not
+need this!
+
+The function returns a handle which will be your ticket to MNG-heaven.
+All other functions rely on this handle. It is the single fixed unique
+reference-point between your application and the library.
+
+You should call the initialization function for each image you wish to
+process simultaneously. If you are processing images consecutively, you can
+reset the internal status of the library with the mng_reset() function.
+This function will clear all internal state variables, free any stored
+chunks and/or objects, etc, etc. Your callbacks and other external parameters
+will be retained.
+
+After you successfully received the handle it is time to set the retquired
+callbacks. The sections on reading, displaying & writing indicate which
+callbacks are retquired and which are optional.
+To set the callbacks simply do:
+
+ myretcode = mng_setcb_xxxxxx (myhandle, my_xxxxxx);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Naturally you'd replace the x's with the name of the callback.
+
+
+> Cleanup
+
+Once you've gotten hold of that precious mng_handle, you should always,
+and I mean always, call the cleanup function when you're done.
+Just do:
+
+ mng_cleanup (myhandle);
+
+And you're done. There shouldn't be an ounce of memory spilled after
+that call.
+
+Note that if you would like to process multiple files consecutively
+you do not need to do mng_cleanup() / mng_initialize() between each file
+but simply
+
+ myretcode = mng_reset (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+will suffice. Saves some time and effort, that.
+
+
+> Error handling
+
+From the examples in the previous paragraphs you may have noticed a
+meticulous scheme for error handling. And yes, that's exactly what it is.
+Practically each call simply returns an errorcode, indicating success,
+eg. MNG_NOERROR or failure, anything else but MNG_NEEDMOREDATA and
+MNG_NEEDTIMERWAIT. These latter two will be discussed in more detail in
+their respective fields of interest: the reading section and displaying
+section respectively.
+
+It is the application's responsibility to check the returncode after
+each call. You can call mng_getlasterror() to receive the details of
+the last detected error. This even includes a discriptive error-message
+if you enabled that option during compilation of the library.
+
+Note that after receiving an error it is still possible to call the
+library, but it's also very likely that any following call will fail.
+The only functions deemed to work will be mng_reset() and mng_cleanup().
+Yes, if you abort your program after an error, you should still call
+mng_cleanup().
+
+
+IV. Reading
+
+Reading a MNG, JNG or PNG is fairly easy. It depends slightly on your
+ultimate goal how certain specifics are to be handled, but the basics
+are similar in all cases.
+
+For the read functioins to work you must have compiled the library with
+the MNG_READ_SUPPRT directive. The standard DLL and Shared Library
+have this on by default!
+
+
+> Setup
+
+Naturally you must have initialized the library and be the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_openstream, mng_readdata, mng_closestream
+
+You may optionally define:
+
+ mng_errorproc, mng_traceproc
+ mng_processheader, mng_processtext
+ mng_processsave, mng_processseek
+
+The reading bit will also fail if you are already creating or
+displaying a file. Seems a bit obvious, but I thought I'd mention it,
+just in case.
+
+
+> To suspend or not to suspend
+
+There is one choice you need to make before calling the read function.
+Are you in need of suspension-mode or not?
+
+If you're reading from a disk you most certainly do not need
+suspension-mode. Even the oldest and slowest of disks will be fast
+enough for straight reading.
+
+However, if your input comes from a really slow device, such as a
+dialup-line or the likes, you may opt for suspension-mode. This is done
+by calling
+
+ myretcode = mng_set_suspensionmode (myhandle,
+ MNG_TRUE);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Suspension-mode will force the library to use special buffering on the
+input. This allows your application to receive data of arbitrarily length
+and return this in the mng_readdata() callback, without disturbing the
+chunk processing routines of the library.
+
+Suspension-mode does retquire a little extra care in the main logic of the
+1application. The read function may return with MNG_NEEDMOREDATA when the
+mng_readdata() callback returns less data then it needs to process the
+next chunk. This indicates the application to wait for more data to arrive
+and then resume processing by calling mng_read_resume().
+
+
+> The read HLAPI
+
+The actual reading is just plain simple. Since all I/O is done
+1outside the library through the callbacks, the library can focus on
+its real task. Understanding, checking and labelling the input data!
+
+All you really need to do is this:
+
+ myretcode = mng_read (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Of course, if you're on suspension-mode the code is a little more
+complicated:
+
+ myretcode = mng_read (myhandle);
+
+ while (myretcode == MNG_NEEDMOREDATA) {
+ /* wait for input-data to arrive */
+ myretcode = mng_read_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+This is rather crude and more sophisticated programming methods may
+dictate another approach. Whatever method you decide on, it should
+act as if the above code was in its place.
+
+There is also the mng_readdisplay() function, but this is discussed
+in the displaying section. It functions pretty much as the mng_read()
+function, but also immediately starts displaying the image.
+mng_read_resume() should be replaced by mng_display_resume() in that
+case!
+
+
+> What happens inside
+
+What actually happens inside the library depends on the configuration
+options set during the compilation of the library.
+
+Basically the library will first read the 8-byte file header, to determine
+its validity and the type of image it is about to process. Then it will
+repeatedly read a 4-byte chunk-length and then the remainder of the chunk
+until it either reaches EOF (indicated by the mng_readdata() callback) or
+implicitly decides EOF as it processed the logically last chunk of the
+image.
+
+Applications that retquire strict conformity and do not allow superfluous
+data after the ending chunk, will need to perform this check in their
+mng_closestream() callback.
+
+Each chunk is then checked on CRC, after which it is handed over to the
+appropriate chunk processing routine. These routines will disect the
+chunk, check the validity of its contents, check its position with respect
+to other chunks, etc, etc.
+
+If everything checks out, the chunk is further processed as follows:
+
+If display support has been selected during compilation, certain pre-display
+initialization will take place.
+
+If chunk-storage support has been selected during compilation, the chunks
+data may be stored in a special internal structure and held for future
+reference.
+
+
+> Storing and accessing chunks
+
+One of the compilation options activates support for chunk storage.
+This option may be useful if you want to examine an image. The directive
+is MNG_STORE_CHUNKS. You must also turn on the MNG_ACCESS_CHUNKS
+directive.
+
+The actual storage facility can be turned on or off with the
+mng_set_storechunks() function. If set to MNG_TRUE, chunks will be
+stored as they are read.
+
+At any point you can then call the mng_iterate_chunks() function
+to iterate through the current list of chunks. This function retquires
+a callback which is called for each chunk and receives a specific
+chunk-handle. This chunk-handle can be used to call the appropriate
+mng_getchunk_xxxx() function, to access the chunks properties.
+
+A typical implementation may look like this:
+
+ mng_bool my_iteratechunk (mng_handle hHandle,
+ mng_handle hChunk,
+ mng_chunkid iChunkid,
+ mng_uint32 iChunkseq) {
+ switch (iChunkid) {
+ case MNG_UINT_MHDR : { /* process MHDR */;
+ break; }
+ case MNG_UINT_FRAM : { /* process FRAM */;
+ break; }
+
+ ...etc...
+
+ case MNG_UINT_HUH : { /* unknown chunk */;
+ break; }
+ default : { /* duh; forgot one */; }
+ }
+
+ return MNG_TRUE; /* keep'm coming */
+ }
+
+To get to the actual chunk fields of lets say a SHOW chunk you would do:
+
+ mng_bool isempty;
+ mng_uint16 firstid, lastid;
+ mng_uint8 showmode;
+
+ myretcode mng_getchunk_show (hHandle, hChunk,
+ isempty, firstid,
+ lastid, showmode);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+
+V. Displaying
+
+
+> Setup
+
+Assuming you have initialized the library and are the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_getcanvasline, mng_refresh
+ mng_gettickcount, mng_settimer
+
+If you wish to use an application supplied background you must supply:
+
+ mng_getbkgdline
+
+If you wish to use the MNG_CANVAS_RGB8_A8 canvas style you must supply:
+
+ mng_getalphaline
+
+You may optionally define:
+
+ mng_errorproc, mng_traceproc
+ mng_processheader, mng_processtext
+ mng_processsave, mng_processseek
+
+Note that the mng_processheader() callback is optional but will
+be tquite significant for proper operation!
+
+Displaying an image will fail if you are creating a file or already
+displaying one. Yes, you can't display it twice!
+
+
+> A word on canvas styles
+
+The canvas style describes how your drawing canvas is made up.
+You must set this before the library actually starts drawing, so
+the mng_processheader() callback is a pretty good place for it.
+
+Currently only 8-bit RGB canvas styles are supported, either with
+or without an alpha channel.
+
+If you like to do alpha composition yourself you can select one of
+the canvas styles that include an alpha channel. You can even have
+a separate alpha canvas by selecting the MNG_CANVAS_RGB8_A8 style.
+
+All styles retquire a compact model. Eg. MNG_CANVAS_BGR8 retquires
+your canvas lines in bgrbgrbgr... storage, where each letter
+represents an 8-bit value of the corresponding color, and each
+threesome makes up the values of one(1) pixel.
+
+The library processes a line at a time, so the canvas lines do not
+actually need to be consecutive in memory.
+
+
+> Alpha composition and application backgrounds
+
+All Network Graphics can be partially transparent. This retquires
+special processing if you need to display an image against some
+background. Note that the MNG header (MHDR chunk) contains a
+simplicity field indicating whether transparency information in
+the file is critical or not. This only applies to embedded images,
+which means the full image-frame of the MNG may still contain fully
+transparent pixels!
+
+Depending on your needs you can supply a single background color,
+a background canvas or tell the library to return the alpha-channel
+and do alpha composition yourself.
+
+This is different from the BACK chunk in a MNG, or the bKGD chunk
+in an (embedded) PNG or JNG. The BACK chunk indicates an optional or
+mandatory background color and/or image. The bKGD chunk only indicates
+an optional background color. These chunks indicate the Authors
+preferences. They may be absent in which case you need to supply
+some sort of background yourself.
+
+> Composing against a background color
+
+This is the easiest method. Call the mng_set_bgcolor() function to
+set the values of the red, green and blue component of your preferred
+background color.
+
+Use one of the canvas styles that do not have an alpha-channel, and
+which matches your output retquirements.
+
+> Composing against a background canvas
+
+This is somewhat more complicated. You will need to set the
+mng_getbkgdline() callback. This will be called whenever the library
+needs to compose a partially transparent line.
+
+This canvas must hold the background against which the image should
+be composed. Its size must match exactly with the image dimensions
+and thus the drawing canvas!
+
+Use one of the canvas styles that do not have an alpha-channel, and
+which matches your output retquirements. The canvas style of the
+background canvas may even differ from the drawing canvas. The library's
+composing will still function properly.
+
+> Composing within the application
+
+If you have the option in your application to draw a (partially)
+transparent canvas to the output device, this option is preferred.
+
+Select one of the canvas styles that do have an alpha-channel.
+The library will now supply the appropriate alpha information,
+allowing the application to compose the image as it sees fit.
+
+
+> Color information and CMS
+
+Network Graphics may, and usually will, contain color-correction
+information. This information is intended to compensate for the
+difference in recording and display devices used.
+
+This document does not address the specifics of color-management.
+See the PNG specification for a more detailed description.
+
+> Using little cms by Marti Maria Saguer
+
+This is the easiest method, providing you can compile the lcms package.
+Select the MNG_FULL_CMS directive during compilation, and sit back and
+relax. The library will take care of all color-correction for you.
+
+> Using an OS- or application-supplied CMS
+
+If you are so lucky to have access to CMS functionality from within
+your application, you may instruct the library to leave color-correction
+to you.
+
+Select the MNG_APP_CMS directive during compilation of the library.
+You MUST also set the following callbacks:
+
+ mng_processgamma, mng_processchroma,
+ mng_processsrgb, mng_processiccp and
+ mng_processarow
+
+The last callback is called when the library needs you to correct
+an arbitrary line of pixels. The other callbacks are called when
+the corresponding color-information is encountered in the file.
+You must store this information somewhere for use in the
+mng_processarow() callback.
+
+> Using gamma-only correction
+
+This isn't a preferred method, but it's better than no correction
+at all. Gamma-only correction will at least compensate for
+gamma-differences between the original recorder and your output device.
+
+Select the MNG_GAMMA_ONLY directive during compilation
+of the library. Your compiler MUST support fp operations.
+
+> No color correction
+
+Ouch. This is really bad. This is the least preferred method,
+but may be necessary if your system cannot use lcms, doesn't
+have its own CMS, and does not allow fp operations, ruling out
+the gamma-only option.
+
+Select the MNG_NO_CMS directive during compilation.
+Images will definitely not be displayed as seen by the Author!!!
+
+
+> Animations and timing
+
+Animations retquire some form of timing support. The library relies
+on two callbacks for this purpose. The mng_gettickcount() and
+mng_settimer() callbacks. mng_gettickcount() is used to determine
+the passing of time in milliseconds since the beginning of the
+animation. This is also used to compensate during suspension-mode
+if you are using the mng_readdisplay() function to read & display
+the file simultaneously.
+
+The callback may return an arbitrary number of milliseconds, but
+this number must increase proportionaly between calls. Most modern
+systems will have some tickcount() function which derives its
+input from an internal clock. The value returned from this function
+is more than adequate for libmng.
+
+The mng_settimer() callback is called when the library determines
+a little "pause" is retquired before rendering another frame of the
+animation. The pause interval is also expressed in milliseconds.
+Your application should store this value and return immediately.
+The library will then make appropriate arrangements to store its
+internal state and returns to your application with the
+MNG_NEEDTIMERWAIT code.
+
+At that point you should suspend processing and wait the given
+interval. Please use your OS features for this. Do not engage some
+sort of loop. That is real bad programming practice. Most modern
+systems will have some timing functions. A simple wait() function
+may suffice, but this may prevent your applications main-task from
+running, and possibly prevent the actual update of your output device.
+
+
+> The mng_refresh() callback
+
+The mng_refresh() callback is called whenever the library has
+"finished" drawing a new frame onto your canvas, and just before it
+will call the mng_settimer() callback.
+
+This allows you to perform some actions necessary to "refresh" the
+canvas onto your output device. Please do NOT suspend processing
+inside this callback. This must be handled after the mng_settimer()
+callback!
+
+
+> Displaying while reading
+
+This method is preferred if you are reading from a slow input device
+(such as a dialup-line) and you wish to start displaying something
+as tquickly as possible. This functionality is provided mainly for
+browser-type applications but may be appropriate for other
+applications as well.
+
+The method is usually used in unison with the suspension-mode of
+the read module. A typical implementation would look like this:
+
+ /* initiale library and set retquired callbacks */
+
+ /* activate suspension-mode */
+ myretcode = mng_set_suspensionmode (myhandle,
+ MNG_TRUE);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+ myretcode = mng_readdisplay (myhandle);
+
+ while ((myretcode == MNG_NEEDMOREDATA) ||
+ (myretcode == MNG_NEEDTIMERWAIT)) {
+ if (myretcode == MNG_NEEDMOREDATA)
+ /* wait for more input-data */;
+ else
+ /* wait for timer interval */;
+
+ myretcode = mng_display_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+More advanced programming methods may retquire a different approach,
+but the final result should function as in the code above.
+
+
+> Displaying after reading
+
+This method is used to display a file that was previously read.
+It is primarily meant for viewers with direct file access, such as
+1a local harddisk.
+
+Once you have successfully read the file, all you need to do is:
+
+ myretcode = mng_display (myhandle);
+
+ while (myretcode == MNG_NEEDTIMERWAIT) {
+ /* wait for timer interval */;
+ myretcode = mng_display_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Again, more advanced programming methods may retquire a different
+approach, but the final result should function as in the code above.
+
+
+> Display manipulation
+
+Several HLAPI functions are provided to allow a user to manipulate
+the normal flow of an animation.
+
+- mng_display_freeze (mng_handle hHandle)
+
+This will "freeze" the animation in place.
+
+- mng_display_resume (mng_handle hHandle)
+
+This function can be used to resume a frozen animation, or to force
+the library to advance the animation to the next frame.
+
+- mng_display_reset (mng_handle hHandle)
+
+This function will "reset" the animation into its pristine state.
+Calling mng_display_resume() afterwards will restart the animation
+from the first frame.
+
+- mng_display_golayer (mng_handle hHandle,
+ mng_uint32 iLayer)
+- mng_display_goframe (mng_handle hHandle,
+ mng_uint32 iFrame)
+- mng_display_goplaytime (mng_handle hHandle,
+ mng_uint32 iPlaytime)
+
+These three functions can be used to "jump" to a specific layer, frame
+or timeslot in the animation. You must "freeze" the animation before
+using any of these functions.
+
+All above functions may only be called during a timer interval!
+It is the applications responsibility to cleanup any resources with
+respect to the timer wait.
+
+
+VI. Writing
+
+The main focus of the library lies in its displaying capabilites.
+But it does offer writing support as well.
+You can create and write a file, or you can write a file you
+have previously read, providing the storage of chunks was enabled
+and active.
+
+For this to work you must have compiled the library with the
+MNG_WRITE_SUPPO1RT and MNG_ACCESS_CHUNKS directives. The standard DLL and
+Shared Library have this on by default!
+
+
+> Setup
+
+As always you must have initialized the library and be the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_openstream, mng_writedata, mng_closestream
+
+You can optionally define:
+
+ mng_errorproc, mng_traceproc
+
+The creation and writing functions will fail if you are in the middle
+of reading, creating or writing a file.
+
+
+> Creating a new file
+
+To start a new file the library must be in its initial state.
+First you need to tell the library your intentions:
+
+ myretcode = mng_create (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+After that you start adding the appropriate chunks:
+
+ myretcode = mng_putchunk_mhdr (myhandle, ...);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+And so on, and so forth. Note that the library will automatically signal
+the logical end of the file by the ending chunk. Also the first chunk
+will indicate the library the filetype (eg. PNG, JNG or MNG) and force
+the proper signature when writing the file.
+
+The code above can be simplified, as you can always get the last errorcode
+by using the mng_getlasterror() function:
+
+ if ( (mng_putchunk_xxxx (myhandle, ...)) or
+ (mng_putchunk_xxxx (myhandle, ...)) or
+ ...etc... )
+ /* process error */;
+
+Please note that you must have a pretty good understanding of the chunk
+specification. Unlike the read functions, there are virtually no checks,
+so it is tquite possible to write completely wrong files.
+It is a good practice to read back your file into the library to verify
+its integrity.
+
+Once you've got all the chunks added, all you do is:
+
+ myretcode mng_write (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+And presto. You're done. The real work is of course carried out in
+your callbacks. Note that this is a single operation as opposed to
+the read & display functions that may return with MNG_NEEDMOREDATA
+and/or MNG_NEEDTIMERWAIT. The write function just does the job, and
+only returns after it's finished or if it encounters some
+unrecoverable error.
+
+
+> Writing a previously read file
+
+If you have already successfully read a file, you can use the library to
+write it out as a copy or something. You MUST have compiled the library
+with the MNG_STORE_CHUNKS directive, and you must have done
+mng_set_storechunks (myhandle, MNG_TRUE).
+
+This doesn't retquire the MNG_ACCESS_CHUNKS directive, unless you want
+to fiddle with the chunks as well.
+
+Again all you need to do is:
+
+ myretcode mng_write (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;

+jng \- JPEG Network Graphics (JNG) sub-format
+.SH DESCRIPTION
+JNG (JPEG Network Graphics) is a sub-format of the MNG (Multiple-image
+Network Graphics) format. As with MNG it extends on the features of the
+popular PNG (Portable Network Graphics) image-format.
+.br
+
+This sub-format was designed to support a lossy compression-method.
+It is based completely on the JPEG specification. It adds the high-compression
+ratios of JPEG for photographic images.
+
+As a member of the Network Graphics family, JNG was deemed adequate as a
+stand-alone format as it extends the JPEG format with color-correction and
+transparency features.

+.TH LIBMNG 3 "June 23rd, 2002"
+.SH NAME
+libmng \- Multiple-image Network Graphics (MNG) Reference Library 1.0.4
+.SH SYNOPSIS
+\fI\fB
+
+\fB#include <libmng.h>\fP
+
+
+.SH DESCRIPTION
+The
+.I libmng
+library supports decoding, displaying, encoding, and various other
+manipulations of the Multiple-image Network Graphics (MNG) format
+image files. It uses the
+.IR zlib(3)
+compression library, and optionally the JPEG library by the Independant
+JPEG Group (IJG) and/or lcms (little cms), a color-management library
+by Marti Maria Saguer.
+
+
+.SH I. Introduction
+
+This file describes how to use and modify the MNG reference library
+(known as libmng) for your own use. There are seven sections to this
+file: introduction, callbacks, housekeeping, reading, displaying,
+writing, and modification and configuration notes for various special
+platforms. We assume that libmng is already installed; see the
+INSTALL.README file for instructions on how to install libmng.
+
+Libmng was written to support and promote the MNG specification.
+
+The MNG-1.0 specification should be shortly available at
+<http://www.libpng.org/pub/mng>.
+
+Other information about MNG can be found at the MNG home page,
+<http://www.libpng.org/pub/mng>.
+The latest version of libmng can be found at its own homepage at
+<http://www.libmng.com>.
+
+In most cases the library will not need to be changed.
+For standardization purposes the library contains both a Windows DLL
+and a makefile for building a shared library (SO). The library is
+written in C, but an interface for Borland Delphi is also available.
+
+Libmng has been designed to handle multiple sessions at one time,
+to be easily modifiable, to be portable to the vast majority of
+machines (ANSI, K&R, 32-, and 64-bit) available, and to be easy
+to use.
+
+Libmng uses zlib for its compression and decompression of MNG files.
+Further information about zlib, and the latest version of zlib, can be
+found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
+The zlib compression utility is a general purpose utility that is
+useful for more than MNG/PNG files, and can be used without libmng.
+See the documentation delivered with zlib for more details.
+
+Libmng optionally uses the JPEG library by the Independant JPEG Group
+(IJG). This library is used for the JNG sub-format, which is part of
+the MNG specification, and allows for inclusion of JPEG decoded and
+thus highly compressed (photographic) images.
+Further information about the IJG JPEG library and the latest sources
+can be found at <http://www.ijg.org>.
+
+Libmng can also optionally use the lcms (little CMS) library by
+Marti Maria Saguer. This library provides an excellent color-management
+system (CMS), which gives libmng the ability to provide full
+color-correction for images with the proper color-information encoded.
+Further information and the latest sources can be found at
+<http://www.littlecms.com/>.
+
+Libmng is thread safe, provided the threads are using different
+handles as returned by the initialization call.
+Each thread should have its own handle and thus its own image.
+Libmng does not protect itself against two threads using the
+same instance of a handle.
+
+The libmng.h header file is the single reference needed for programming
+with libmng:
+
+#include <libmng.h>
+
+
+.SH II. Callbacks
+
+Libmng makes extensive use of callback functions. This is meant to
+keep the library as platform-independant and flexible as possible.
+Actually, the first call you will make to the library, already contains
+three parameters you can use to provide callback entry-points.
+
+Most functions must return a mng_bool (boolean). Returning MNG_FALSE
+indicates the library the callback failed in some way and the library
+will immediately return from whatever it was doing back to the
+application. Returning MNG_TRUE indicates there were no problems and
+processing can continue.
+
+Let's step through each of the possible callbacks. The sections on
+reading, displaying and writing will also explain which callbacks are
+needed when and where.
+
+\- mng_ptr mng_memalloc (mng_size_t iLen)
+
+A very basic function which the library uses to allocate a memory-block
+with the given size. A typical implementation would be:
+
+ mng_ptr my_alloc (mng_size_t iLen) {
+ return calloc (1, iSize);
+ }
+
+Note that the library retquires you to zero-out the memory-block!!!
+
+\- void mng_memfree (mng_ptr pPtr,
+ mng_size_t iLen)
+
+Counterpart of the previous function. Typically:
+
+ void my_free (mng_ptr pPtr, mng_size_t iLen) {
+ free (pPtr);
+ }
+
+\- mng_bool mng_openstream (mng_handle hHandle)
+
+\- mng_bool mng_closestream (mng_handle hHandle)
+
+These are called by the library just before it starts to process
+(either read or write) a file and just after the processing stops.
+This is the recommended place to do I/O initialization & finalization.
+Whether you do or not, is up to you. The library does not put any
+meaning into the calls. They are simply provided for your convenience.
+
+\- mng_bool mng_readdata (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pRead)
+
+This function is called when the library needs some more input while
+reading an image. The reading process supports two modes:
+Suspension-mode (SMOD) and non-suspension-mode (NSMOD).
+See mng_set_suspensionmode() for a more detailed description.
+
+In NSMOD, the library retquires you to return exactly the amount of bytes
+requested (= iBuflen). Any lesser amount indicates the input file
+is exhausted and the library will return a MNG_UNEXPECTEDEOF errorcode.
+
+In SMOD, you may return a smaller amount of bytes than requested.
+This tells the library it should temporarily wait for more input to
+arrive. The lib will return with MNG_NEEDMOREDATA, and will expect a
+call to mng_read_resume() or mng_display_resume() next, as soon as
+more input-data has arrived.
+
+For NSMOD this function could be as simple as:
+
+ mng_bool my_read (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pRead) {
+ *pRead = fread (pBuf, 1, iBuflen, myfile);
+ return MNG_TRUE;
+ }
+
+\- mng_bool mng_writedata (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pWritten)
+
+This function is called during the mng_write() function to actually
+output data to the file. There is no suspension-mode during write,
+so the application must return the exact number of bytes the library
+requests to be written.
+
+A typical implementation could be:
+
+ mng_bool my_write (mng_handle hHandle,
+ mng_ptr pBuf,
+ mng_uint32 iBuflen,
+ mng_uint32p pWritten) {
+ *pWritten = fwrite (pBuf, 1, iBuflen, myfile);
+ return MNG_TRUE;
+ }
+
+\- mng_bool mng_errorproc (mng_handle hHandle,
+ mng_int32 iErrorcode,
+ mng_int8 iSeverity,
+ mng_chunkid iChunkname,
+ mng_uint32 iChunkseq,
+ mng_int32 iExtra1,
+ mng_int32 iExtra2,
+ mng_pchar zErrortext)
+
+This function is called whenever an error is detected inside the
+library. This may be caused by invalid input, callbacks indicating
+failure, or wrongfully calling functions out of place.
+
+If you do not provide this callback the library will still return
+an errorcode from the called function, and the mng_getlasterror()
+function can be used to retrieve the other parameters.
+
+This function is currently only provided for convenience, but may
+at some point be used to indicate certain errors may be acceptable,
+and processing should continue.
+
+\- mng_bool mng_traceproc (mng_handle hHandle,
+ mng_int32 iFuncnr,
+ mng_int32 iFuncseq,
+ mng_pchar zFuncname)
+
+This function is provided to allow a functional analysis of the
+library. This may be useful if you encounter certain errors and
+cannot determine what the problem is.
+
+Almost all functions inside the library will activate this
+callback with an appropriate function-name at the start and end
+of the function. Please note that large images may generate an
+enormous amount of calls.
+
+\- mng_bool mng_processheader (mng_handle hHandle,
+ mng_uint32 iWidth,
+ mng_uint32 iHeight)
+
+This function is called once the header information of an input-
+image has been processed. At this point the image dimensions are
+available and also some other properties depending on the type
+of the image. Eg. for a MNG the frame-/layercount, playtime &
+simplicity fields are known.
+
+The primary purpose of this callback is to inform the application
+of the size of the image, and for the application to initialize
+the drawing canvas to be used by the library. This is also a good
+point to set the canvas-style. Eg. mng_set_canvasstyle().
+
+\- mng_bool mng_processtext (mng_handle hHandle,
+ mng_uint8 iType,
+ mng_pchar zKeyword,
+ mng_pchar zText,
+ mng_pchar zLanguage,
+ mng_pchar zTranslation)
+
+This callback is activated for each textual chunk in the input-
+image. These are tEXt, zTXt & iTXt. It may be used to retain
+specific comments for presentation to the user.
+
+\- mng_bool mng_processsave (mng_handle hHandle)
+
+\- mng_bool mng_processseek (mng_handle hHandle,
+ mng_pchar zName)
+
+The purpose of these callbacks is to signal the processing of the
+SAVE & SEEK chunks in a MNG input-file. This may be used in the
+future to specify some special processing. At the moment these
+functions are only provided as a signal.
+
+\- mng_ptr mng_getcanvasline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+
+\- mng_ptr mng_getbkgdline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+
+\- mng_ptr mng_getalphaline (mng_handle hHandle,
+ mng_uint32 iLinenr)
+
+These callbacks are used to access the drawing canvas, background
+canvas and an optional separate alpha-channel canvas. The latter is
+used only with the MNG_CANVAS_RGB8_A8 canvas-style.
+
+If the getbkgdline() callback is not supplied the library will
+composite full or partially transparent pixels in the image against
+a specified background color. See mng_set_bgcolor() for more details.
+If a chosen canvas-style includes an alpha-channel, this callback
+is very likely not needed.
+
+The application is responsible for returning a pointer to a line of
+pixels, which should be in the exact format as defined by the call
+to mng_set_canvasstyle() and mng_set_bkgdstyle(), without gaps between
+the representation of each pixel.
+
+\- mng_bool mng_refresh (mng_handle hHandle,
+ mng_uint32 iX,
+ mng_uint32 iY,
+ mng_uint32 iWidth,
+ mng_uint32 iHeight)
+
+This callback is called when the library has drawn a complete frame
+onto the drawing canvas, and it is ready to be displayed.
+The application is responsible for transferring the drawing canvas
+from memory onto the actual output device.
+
+\- mng_uint32 mng_gettickcount (mng_handle hHandle)
+
+This function should return the number of milliseconds on some internal
+clock. The entire animation timing depends heavily on this function,
+1and the number returned should be as accurate as possible.
+
+\- mng_bool mng_settimer (mng_handle hHandle,
+ mng_uint32 iMsecs)
+
+This callback is activated every time the library retquires a "pause".
+Note that the function itself should NOT execute the wait. It should
+simply store the time-field and allow the library to return. Libmng
+will return with the MNG_NEEDTIMERWAIT code, indicating the callback
+was called and it is now time to execute the pause.
+
+After the indicated number of milliseconds have elapsed, the application
+should call mng_display_resume(), to resume the animation as planned.
+
+This method allows for both a real timer or a simple wait command in the
+application. Whichever method you select, both the gettickcount() and
+settimer() callbacks are crucial for proper animation timing.
+
+\- mng_bool mng_processgamma (mng_handle hHandle,
+ mng_uint32 iGamma)
+
+\- mng_bool mng_processchroma (mng_handle hHandle,
+ mng_uint32 iWhitepointx,
+ mng_uint32 iWhitepointy,
+ mng_uint32 iRedx,
+ mng_uint32 iRedy,
+ mng_uint32 iGreenx,
+ mng_uint32 iGreeny,
+ mng_uint32 iBluex,
+ mng_uint32 iBluey)
+
+\- mng_bool mng_processsrgb (mng_handle hHandle,
+ mng_uint8 iRenderingintent)
+
+\- mng_bool mng_processiccp (mng_handle hHandle,
+ mng_uint32 iProfilesize,
+ mng_ptr pProfile)
+
+\- mng_bool mng_processarow (mng_handle hHandle,
+ mng_uint32 iRowsamples,
+ mng_bool bIsRGBA16,
+ mng_ptr pRow)
+
+These callbacks are only retquired when you selected the MNG_APP_CMS
+directive during compilation of the library. See the configuration
+section for more details.
+
+\- mng_bool mng_iteratechunk (mng_handle hHandle,
+ mng_handle hChunk,
+ mng_chunkid iChunkid,
+ mng_uint32 iChunkseq)
+
+This callback is only used for the mng_iterate_chunks() function.
+It is called exactly once for each chunk stored.
+
+
+.SH III. Housekeeping
+
+
+.SS Memory management
+
+The library can use internal memory allocation/deallocation or use
+provided callbacks for its memory management. The choice is made at
+compilation time. See the section on customization for details.
+
+If internal management has been selected, the memory callback functions
+need not be supplied. Even if you do supply them they will not be used.
+The actual code used is similar to the code discussed in the callback
+section:
+
+ pPtr = calloc (1, iSize);
+
+ free (pPtr);
+
+If your compiler does not support these functions, or you wish to monitor
+the library's use of memory for certain reasons, you can choose to
+compile the library with external memory management. In this case the
+memory callback functions MUST be supplied, and should function as if the
+above code was used.
+
+
+.SS Initialization
+
+The basic initialization of the library is short and swift:
+
+ myhandle = mng_initialize (myuserdata, my_alloc,
+ my_free, MNG_NULL);
+ if (myhandle == MNG_NULL)
+ /* process error */;
+
+The first field is an application-only parameter. It is saved in
+libmng's internal structures and available at all times through the
+mng_get_userdata() function. This is especially handy in callback functions
+if your program may be handling multiple files at the same time.
+
+The second and third field supply the library with the memory callback
+1function entry-points. These are described in more detail in the callback
+section and the previous paragraph.
+
+The fourth and last field may be used to supply the library with the
+entry-point of a trace callback function. For regular use you will not
+need this!
+
+The function returns a handle which will be your ticket to MNG-heaven.
+All other functions rely on this handle. It is the single fixed unique
+reference-point between your application and the library.
+
+You should call the initialization function for each image you wish to
+process simultaneously. If you are processing images consecutively, you can
+reset the internal status of the library with the mng_reset() function.
+This function will clear all internal state variables, free any stored
+chunks and/or objects, etc, etc. Your callbacks and other external parameters
+will be retained.
+
+After you successfully received the handle it is time to set the retquired
+callbacks. The sections on reading, displaying & writing indicate which
+callbacks are retquired and which are optional.
+To set the callbacks simply do:
+
+ myretcode = mng_setcb_xxxxxx (myhandle, my_xxxxxx);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Naturally you'd replace the x's with the name of the callback.
+
+
+.SS Cleanup
+
+Once you've gotten hold of that precious mng_handle, you should always,
+and I mean always, call the cleanup function when you're done.
+Just do:
+
+ mng_cleanup (myhandle);
+
+And you're done. There shouldn't be an ounce of memory spilled after
+that call.
+
+Note that if you would like to process multiple files consecutively
+you do not need to do mng_cleanup() / mng_initialize() between each file
+but simply
+
+ myretcode = mng_reset (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+will suffice. Saves some time and effort, that.
+
+
+.SS Error handling
+
+From the examples in the previous paragraphs you may have noticed a
+meticulous scheme for error handling. And yes, that's exactly what it is.
+Practically each call simply returns an errorcode, indicating success,
+eg. MNG_NOERROR or failure, anything else but MNG_NEEDMOREDATA and
+MNG_NEEDTIMERWAIT. These latter two will be discussed in more detail in
+their respective fields of interest: the reading section and displaying
+section respectively.
+
+It is the application's responsibility to check the returncode after
+each call. You can call mng_getlasterror() to receive the details of
+the last detected error. This even includes a discriptive error-message
+if you enabled that option during compilation of the library.
+
+Note that after receiving an error it is still possible to call the
+library, but it's also very likely that any following call will fail.
+The only functions deemed to work will be mng_reset() and mng_cleanup().
+Yes, if you abort your program after an error, you should still call
+mng_cleanup().
+
+
+.SH IV. Reading
+
+Reading a MNG, JNG or PNG is fairly easy. It depends slightly on your
+ultimate goal how certain specifics are to be handled, but the basics
+are similar in all cases.
+
+For the read functioins to work you must have compiled the library with
+the MNG_READ_SUPPRT directive. The standard DLL and Shared Library
+have this on by default!
+
+
+.SS Setup
+
+Naturally you must have initialized the library and be the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_openstream, mng_readdata, mng_closestream
+
+You may optionally define:
+
+ mng_errorproc, mng_traceproc
+ mng_processheader, mng_processtext
+ mng_processsave, mng_processseek
+
+The reading bit will also fail if you are already creating or
+displaying a file. Seems a bit obvious, but I thought I'd mention it,
+just in case.
+
+
+.SS To suspend or not to suspend
+
+There is one choice you need to make before calling the read function.
+Are you in need of suspension-mode or not?
+
+If you're reading from a disk you most certainly do not need
+suspension-mode. Even the oldest and slowest of disks will be fast
+enough for straight reading.
+
+However, if your input comes from a really slow device, such as a
+dialup-line or the likes, you may opt for suspension-mode. This is done
+by calling
+
+ myretcode = mng_set_suspensionmode (myhandle,
+ MNG_TRUE);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Suspension-mode will force the library to use special buffering on the
+input. This allows your application to receive data of arbitrarily length
+and return this in the mng_readdata() callback, without disturbing the
+chunk processing routines of the library.
+
+Suspension-mode does retquire a little extra care in the main logic of the
+1application. The read function may return with MNG_NEEDMOREDATA when the
+mng_readdata() callback returns less data then it needs to process the
+next chunk. This indicates the application to wait for more data to arrive
+and then resume processing by calling mng_read_resume().
+
+
+.SS The read HLAPI
+
+The actual reading is just plain simple. Since all I/O is done
+1outside the library through the callbacks, the library can focus on
+its real task. Understanding, checking and labelling the input data!
+
+All you really need to do is this:
+
+ myretcode = mng_read (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Of course, if you're on suspension-mode the code is a little more
+complicated:
+
+ myretcode = mng_read (myhandle);
+
+ while (myretcode == MNG_NEEDMOREDATA) {
+ /* wait for input-data to arrive */
+ myretcode = mng_read_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+This is rather crude and more sophisticated programming methods may
+dictate another approach. Whatever method you decide on, it should
+act as if the above code was in its place.
+
+There is also the mng_readdisplay() function, but this is discussed
+in the displaying section. It functions pretty much as the mng_read()
+function, but also immediately starts displaying the image.
+mng_read_resume() should be replaced by mng_display_resume() in that
+case!
+
+
+.SS What happens inside
+
+What actually happens inside the library depends on the configuration
+options set during the compilation of the library.
+
+Basically the library will first read the 8-byte file header, to determine
+its validity and the type of image it is about to process. Then it will
+repeatedly read a 4-byte chunk-length and then the remainder of the chunk
+until it either reaches EOF (indicated by the mng_readdata() callback) or
+implicitly decides EOF as it processed the logically last chunk of the
+image.
+
+Applications that retquire strict conformity and do not allow superfluous
+data after the ending chunk, will need to perform this check in their
+mng_closestream() callback.
+
+Each chunk is then checked on CRC, after which it is handed over to the
+appropriate chunk processing routine. These routines will disect the
+chunk, check the validity of its contents, check its position with respect
+to other chunks, etc, etc.
+
+If everything checks out, the chunk is further processed as follows:
+
+If display support has been selected during compilation, certain pre-display
+initialization will take place.
+
+If chunk-storage support has been selected during compilation, the chunks
+data may be stored in a special internal structure and held for future
+reference.
+
+
+.SS Storing and accessing chunks
+
+One of the compilation options activates support for chunk storage.
+This option may be useful if you want to examine an image. The directive
+is MNG_STORE_CHUNKS. You must also turn on the MNG_ACCESS_CHUNKS
+directive.
+
+The actual storage facility can be turned on or off with the
+mng_set_storechunks() function. If set to MNG_TRUE, chunks will be
+stored as they are read.
+
+At any point you can then call the mng_iterate_chunks() function
+to iterate through the current list of chunks. This function retquires
+a callback which is called for each chunk and receives a specific
+chunk-handle. This chunk-handle can be used to call the appropriate
+mng_getchunk_xxxx() function, to access the chunks properties.
+
+A typical implementation may look like this:
+
+ mng_bool my_iteratechunk (mng_handle hHandle,
+ mng_handle hChunk,
+ mng_chunkid iChunkid,
+ mng_uint32 iChunkseq) {
+ switch (iChunkid) {
+ case MNG_UINT_MHDR : { /* process MHDR */;
+ break; }
+ case MNG_UINT_FRAM : { /* process FRAM */;
+ break; }
+
+ ...etc...
+
+ case MNG_UINT_HUH : { /* unknown chunk */;
+ break; }
+ default : { /* duh; forgot one */; }
+ }
+
+ return MNG_TRUE; /* keep'm coming */
+ }
+
+To get to the actual chunk fields of lets say a SHOW chunk you would do:
+
+ mng_bool isempty;
+ mng_uint16 firstid, lastid;
+ mng_uint8 showmode;
+
+ myretcode mng_getchunk_show (hHandle, hChunk,
+ isempty, firstid,
+ lastid, showmode);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+
+.SH V. Displaying
+
+
+.SS Setup
+
+Assuming you have initialized the library and are the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_getcanvasline, mng_refresh
+ mng_gettickcount, mng_settimer
+
+If you wish to use an application supplied background you must supply:
+
+ mng_getbkgdline
+
+If you wish to use the MNG_CANVAS_RGB8_A8 canvas style you must supply:
+
+ mng_getalphaline
+
+You may optionally define:
+
+ mng_errorproc, mng_traceproc
+ mng_processheader, mng_processtext
+ mng_processsave, mng_processseek
+
+Note that the mng_processheader() callback is optional but will
+be tquite significant for proper operation!
+
+Displaying an image will fail if you are creating a file or already
+displaying one. Yes, you can't display it twice!
+
+
+.SS A word on canvas styles
+
+The canvas style describes how your drawing canvas is made up.
+You must set this before the library actually starts drawing, so
+the mng_processheader() callback is a pretty good place for it.
+
+Currently only 8-bit RGB canvas styles are supported, either with
+or without an alpha channel.
+
+If you like to do alpha composition yourself you can select one of
+the canvas styles that include an alpha channel. You can even have
+a separate alpha canvas by selecting the MNG_CANVAS_RGB8_A8 style.
+
+All styles retquire a compact model. Eg. MNG_CANVAS_BGR8 retquires
+your canvas lines in bgrbgrbgr... storage, where each letter
+represents an 8-bit value of the corresponding color, and each
+threesome makes up the values of one(1) pixel.
+
+The library processes a line at a time, so the canvas lines do not
+actually need to be consecutive in memory.
+
+
+.SS Alpha composition and application backgrounds
+
+All Network Graphics can be partially transparent. This retquires
+special processing if you need to display an image against some
+background. Note that the MNG header (MHDR chunk) contains a
+simplicity field indicating whether transparency information in
+the file is critical or not. This only applies to embedded images,
+which means the full image-frame of the MNG may still contain fully
+transparent pixels!
+
+Depending on your needs you can supply a single background color,
+a background canvas or tell the library to return the alpha-channel
+and do alpha composition yourself.
+
+This is different from the BACK chunk in a MNG, or the bKGD chunk
+in an (embedded) PNG or JNG. The BACK chunk indicates an optional or
+mandatory background color and/or image. The bKGD chunk only indicates
+an optional background color. These chunks indicate the Authors
+preferences. They may be absent in which case you need to supply
+some sort of background yourself.
+
+.SS Composing against a background color
+
+This is the easiest method. Call the mng_set_bgcolor() function to
+set the values of the red, green and blue component of your preferred
+background color.
+
+Use one of the canvas styles that do not have an alpha-channel, and
+which matches your output retquirements.
+
+.SS Composing against a background canvas
+
+This is somewhat more complicated. You will need to set the
+mng_getbkgdline() callback. This will be called whenever the library
+needs to compose a partially transparent line.
+
+This canvas must hold the background against which the image should
+be composed. Its size must match exactly with the image dimensions
+and thus the drawing canvas!
+
+Use one of the canvas styles that do not have an alpha-channel, and
+which matches your output retquirements. The canvas style of the
+background canvas may even differ from the drawing canvas. The library's
+composing will still function properly.
+
+.SS Composing within the application
+
+If you have the option in your application to draw a (partially)
+transparent canvas to the output device, this option is preferred.
+
+Select one of the canvas styles that do have an alpha-channel.
+The library will now supply the appropriate alpha information,
+allowing the application to compose the image as it sees fit.
+
+
+.SS Color information and CMS
+
+Network Graphics may, and usually will, contain color-correction
+information. This information is intended to compensate for the
+difference in recording and display devices used.
+
+This document does not address the specifics of color-management.
+See the PNG specification for a more detailed description.
+
+.SS Using little cms by Marti Maria Saguer
+
+This is the easiest method, providing you can compile the lcms package.
+Select the MNG_FULL_CMS directive during compilation, and sit back and
+relax. The library will take care of all color-correction for you.
+
+.SS Using an OS- or application-supplied CMS
+
+If you are so lucky to have access to CMS functionality from within
+your application, you may instruct the library to leave color-correction
+to you.
+
+Select the MNG_APP_CMS directive during compilation of the library.
+You MUST also set the following callbacks:
+
+ mng_processgamma, mng_processchroma,
+ mng_processsrgb, mng_processiccp and
+ mng_processarow
+
+The last callback is called when the library needs you to correct
+an arbitrary line of pixels. The other callbacks are called when
+the corresponding color-information is encountered in the file.
+You must store this information somewhere for use in the
+mng_processarow() callback.
+
+.SS Using gamma-only correction
+
+This isn't a preferred method, but it's better than no correction
+at all. Gamma-only correction will at least compensate for
+gamma-differences between the original recorder and your output device.
+
+Select the MNG_GAMMA_ONLY directive during compilation
+of the library. Your compiler MUST support fp operations.
+
+.SS No color correction
+
+Ouch. This is really bad. This is the least preferred method,
+but may be necessary if your system cannot use lcms, doesn't
+have its own CMS, and does not allow fp operations, ruling out
+the gamma-only option.
+
+Select the MNG_NO_CMS directive during compilation.
+Images will definitely not be displayed as seen by the Author!!!
+
+
+.SS Animations and timing
+
+Animations retquire some form of timing support. The library relies
+on two callbacks for this purpose. The mng_gettickcount() and
+mng_settimer() callbacks. mng_gettickcount() is used to determine
+the passing of time in milliseconds since the beginning of the
+animation. This is also used to compensate during suspension-mode
+if you are using the mng_readdisplay() function to read & display
+the file simultaneously.
+
+The callback may return an arbitrary number of milliseconds, but
+this number must increase proportionaly between calls. Most modern
+systems will have some tickcount() function which derives its
+input from an internal clock. The value returned from this function
+is more than adequate for libmng.
+
+The mng_settimer() callback is called when the library determines
+a little "pause" is retquired before rendering another frame of the
+animation. The pause interval is also expressed in milliseconds.
+Your application should store this value and return immediately.
+The library will then make appropriate arrangements to store its
+internal state and returns to your application with the
+MNG_NEEDTIMERWAIT code.
+
+At that point you should suspend processing and wait the given
+interval. Please use your OS features for this. Do not engage some
+sort of loop. That is real bad programming practice. Most modern
+systems will have some timing functions. A simple wait() function
+may suffice, but this may prevent your applications main-task from
+running, and possibly prevent the actual update of your output device.
+
+
+.SS The mng_refresh() callback
+
+The mng_refresh() callback is called whenever the library has
+"finished" drawing a new frame onto your canvas, and just before it
+will call the mng_settimer() callback.
+
+This allows you to perform some actions necessary to "refresh" the
+canvas onto your output device. Please do NOT suspend processing
+inside this callback. This must be handled after the mng_settimer()
+callback!
+
+
+.SS Displaying while reading
+
+This method is preferred if you are reading from a slow input device
+(such as a dialup-line) and you wish to start displaying something
+as tquickly as possible. This functionality is provided mainly for
+browser-type applications but may be appropriate for other
+applications as well.
+
+The method is usually used in unison with the suspension-mode of
+the read module. A typical implementation would look like this:
+
+ /* initiale library and set retquired callbacks */
+
+ /* activate suspension-mode */
+ myretcode = mng_set_suspensionmode (myhandle,
+ MNG_TRUE);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+ myretcode = mng_readdisplay (myhandle);
+
+ while ((myretcode == MNG_NEEDMOREDATA) ||
+ (myretcode == MNG_NEEDTIMERWAIT)) {
+ if (myretcode == MNG_NEEDMOREDATA)
+ /* wait for more input-data */;
+ else
+ /* wait for timer interval */;
+
+ myretcode = mng_display_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+More advanced programming methods may retquire a different approach,
+but the final result should function as in the code above.
+
+
+.SS Displaying after reading
+
+This method is used to display a file that was previously read.
+It is primarily meant for viewers with direct file access, such as
+1a local harddisk.
+
+Once you have successfully read the file, all you need to do is:
+
+ myretcode = mng_display (myhandle);
+
+ while (myretcode == MNG_NEEDTIMERWAIT) {
+ /* wait for timer interval */;
+ myretcode = mng_display_resume (myhandle);
+ }
+
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+Again, more advanced programming methods may retquire a different
+approach, but the final result should function as in the code above.
+
+
+.SS Display manipulation
+
+Several HLAPI functions are provided to allow a user to manipulate
+the normal flow of an animation.
+
+\- mng_display_freeze (mng_handle hHandle)
+
+This will "freeze" the animation in place.
+
+\- mng_display_resume (mng_handle hHandle)
+
+This function can be used to resume a frozen animation, or to force
+the library to advance the animation to the next frame.
+
+\- mng_display_reset (mng_handle hHandle)
+
+This function will "reset" the animation into its pristine state.
+Calling mng_display_resume() afterwards will restart the animation
+from the first frame.
+
+\- mng_display_golayer (mng_handle hHandle,
+ mng_uint32 iLayer)
+
+\- mng_display_goframe (mng_handle hHandle,
+ mng_uint32 iFrame)
+
+\- mng_display_goplaytime (mng_handle hHandle,
+ mng_uint32 iPlaytime)
+
+These three functions can be used to "jump" to a specific layer, frame
+or timeslot in the animation. You must "freeze" the animation before
+using any of these functions.
+
+All above functions may only be called during a timer interval!
+It is the applications responsibility to cleanup any resources with
+respect to the timer wait.
+
+
+.SH VI. Writing
+
+The main focus of the library lies in its displaying capabilites.
+But it does offer writing support as well.
+You can create and write a file, or you can write a file you
+have previously read, providing the storage of chunks was enabled
+and active.
+
+For this to work you must have compiled the library with the
+MNG_WRITE_SUPPO1RT and MNG_ACCESS_CHUNKS directives. The standard DLL and
+Shared Library have this on by default!
+
+
+.SS Setup
+
+As always you must have initialized the library and be the owner of
+a mng_handle. The following callbacks are essential:
+
+ mng_openstream, mng_writedata, mng_closestream
+
+You can optionally define:
+
+ mng_errorproc, mng_traceproc
+
+The creation and writing functions will fail if you are in the middle
+of reading, creating or writing a file.
+
+
+.SS Creating a new file
+
+To start a new file the library must be in its initial state.
+First you need to tell the library your intentions:
+
+ myretcode = mng_create (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+After that you start adding the appropriate chunks:
+
+ myretcode = mng_put1chunk_mhdr (myhandle, ...);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+And so on, and so forth. Note that the library will automatically signal
+the logical end of the file by the ending chunk. Also the first chunk
+will indicate the library the filetype (eg. PNG, JNG or MNG) and force
+the proper signature when writing the file.
+
+The code above can be simplified, as you can always get the last errorcode
+by using the mng_getlasterror() function:
+
+ if ( (mng_putchunk_xxxx (myhandle, ...)) or
+ (mng_putchunk_xxxx (myhandle, ...)) or
+ ...etc... )
+ /* process error */;
+
+Please note that you must have a pretty good understanding of the chunk
+specification. Unlike the read functions, there are virtually no checks,
+so it is tquite possible to write completely wrong files.
+It is a good practice to read back your file into the library to verify
+its integrity.
+
+Once you've got all the chunks added, all you do is:
+
+ myretcode mng_write (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+
+And presto. You're done. The real work is of course carried out in
+your callbacks. Note that this is a single operation as opposed to
+the read & display functions that may return with MNG_NEEDMOREDATA
+and/or MNG_NEEDTIMERWAIT. The write function just does the job, and
+only returns after it's finished or if it encounters some
+unrecoverable error.
+
+
+.SS Writing a previously read file
+
+If you have already successfully read a file, you can use the library to
+write it out as a copy or something. You MUST have compiled the library
+with the MNG_STORE_CHUNKS directive, and you must have done
+mng_set_storechunks (myhandle, MNG_TRUE).
+
+This doesn't retquire the MNG_ACCESS_CHUNKS directive, unless you want
+to fiddle with the chunks as well.
+
+Again all you need to do is:
+
+ myretcode mng_write (myhandle);
+ if (myretcode != MNG_NOERROR)
+ /* process error */;
+

+.SH NAME
+mng \- Multiple-image Network Graphics (MNG) format
+.SH DESCRIPTION
+MNG (Multiple-image Network Graphics) is the animation extension of the
+popular PNG image-format. PNG (Portable Network Graphics) is an
+extensible file format for the lossless, portable, well-compressed
+storage of raster images.
+.br
+
+MNG has advanced animation features which make it very useful as a full
+replacement for GIF animations. These features allow animations that
+are impossible with GIF or result in much smaller files as GIF.
+
+As MNG builds on the same structure as PNG, it is robust, extensible and
+free of patents. It retains the same clever file integrity checks as in PNG.
+
+MNG also embraces the lossy JPEG image-format in a sub-format named JNG,
+which allows for alpha-transparency and color-correction on highly
+compressed (photographic) images.

+ If you have defined MNG_FULL_CMS (and are using lcms), you will have to
+ think hard about the following routines.
+
+ lcms retquires 2 profiles to work off the differences in the input-image
+ and the output-device. The ICC profile for the input-image will be
+ embedded within it to reflect its color-characteristics, but the output
+ profile depends on the output-device, which is something only *YOU* know
+ about. sRGB (standard RGB) is common for x86 compatible environments
+ (eg. Windows, Linux and some others)
+
+ If you are compiling for a sRGB compliant system you probably won't have
+ to do anything special. (unless you want to ofcourse)
+
+ If you are compiling for a non-sRGB compliant system
+ (eg. SGI, Mac, Next, others...)
+ you *MUST* define a proper ICC profile for the generic output-device
+ associated with that platform.
+
+ In either event, you may also want to offer an option to your users to
+ set the profile manually, or, if you know how, set it from a
+ system-defined default.
+
+ TO RECAP: for sRGB systems (Windows, Linux) no action retquired!
+ for non-sRGB systems (SGI, Mac, Next) ACTION RETQUIRED!
