The Document class represents a media file. It +uses the "State" design pattern to adapt its behavior depending on its state. +The various states are implemented in the Document*Impl classes. +It knows how to load, save, edit a comment, rotate and mirror a document. + + +### Image loader and cache +imageloader.h +cache.h + +Image loading is done by the ImageLoader classes, which work together with the +cache to avoid loading an image multiple times. +A loader may be shared, for example if an image is selected and a thumbnail of +it is being generated, the same loader will be used by both. + + +### File views +fileviewcontroller.h +filedetailview*.h +filethumbnailview*.h +fileviewbase.h + +The main class is FileViewController, which contains the KDirLister responsible +for listing folder content. It also contains a QWidgetStack which contains +both the FileDetailView and the FileThumbnailView. +FileViewBase is an abstract class, which inherits from KFileView and adds the +concept of a "shown item": the item currently viewed in the image view. + + +### Image view +imageview.h +imageviewtools.h + +The ImageView class inherits from QScrollView to show the current image. It +implements zooming and panning. +The ImageViewTools implements the different behaviors: for example when you +use the mouse wheel you will scroll (or browse): This is implemented by the +ImageView::ScrollTool class. If you press Ctrl and use the mouse wheel, you +will zoom in the image: This is implemented by the ImageView::ZoomTool. + + +### ImageViewController + +ImageViewController contains a stack which contains an ImageView and a KPart. +The ImageView class is used to show raster images. For SVG images and movies, +the ImageViewController loads the corresponding KPart. + + +### File operations +fileoperation.h +fileopobject.h + +These classes implements file operations: from the user interface to the actual +operation. + + +## app + +### Main window +mainwindow.h + +The MainWindow class is responsible for gluing together all components of the +application. It is made of a QWidgetStack which contains two pages: one for +the docked windows (==Browse mode) and another for the ImageViewController +(==View and Fullscreen modes). +There is only one instance of ImageViewController. It is 'reparent'ed when the +QWidgetStack switch between modes. + + +### Folder view +dirviewcontroller.h +vtabwidget.h +bookmarkviewcontroller.h +treeview.h + +These classes implement the folder view.

It features a folder tree window and a file list window to provide easy navigation of your file hierarchy. Gwenview uses docked windows, so you can alter its layout any way you wish. You can also browse your images in full\-screen mode, or embedded within Konqueror using the Gwenview Image Browser View and Kpart. +.PP +Image loading is handled by the Qt library, so Gwenview supports all image formats your Qt installation supports. Gwenview correctly displays images with an alpha channel. +.PP +Gwenview supports the displaying and editing of EXIF comments, if the necessary JPEG kfile\-plugin is installed. This comes as part of the kdegraphics package. Lossless JPEG transforms are also supported. +.SH OPTIONS +.SS Arguments: +.TP +.B file or folder +An initial image file, or a folder containing images. +.SS Gwenview options: +.TP +.B \-f +Start in Full Screen mode. +.SS Generic options: +.TP +.B \-\-help +Show help about options. +.TP +.B \-\-help\-qt +Show Qt specific options. +.TP +.B \-\-help\-kde +Show KDE specific options. +.TP +.B \-\-help\-all +Show all options. +.TP +.B \-\-author +Show author information. +.TP +.B \-v\fR, \fB\-\-version +Show version information. +.TP +.B \-\-license +Show license information. +.TP +.B \-\- +End of options. +.SS Qt options: +.TP +.B \-\-display \fIdisplayname\fR +Use the X\-server display 'displayname'. +.TP +.B \-\-session \fIsessionId\fR +Restore the application for the given 'sessionId'. +.TP +.B \-\-cmap +Causes the application to install a private color +map on an 8\-bit display. +.TP +.B \-\-ncols \fIcount\fR +Limits the number of colors allocated in the color +cube on an 8\-bit display, if the application is +using the QApplication::ManyColor color +specification. +.TP +.B \-\-nograb +Tells Qt to never grab the mouse or the keyboard. +.TP +.B \-\-dograb +Running under a debugger can cause an implicit +\-nograb, use \-dograb to override. +.TP +.B \-\-sync +Switches to synchronous mode for debugging. +.TP +.B \-\-fn\fR, \fB\-\-font \fIfontname\fR +Defines the application font. +.TP +.B \-\-bg\fR, \fB\-\-background \fIcolor\fR +Sets the default background color and an +application palette (light and dark shades are +calculated). +.TP +.B \-\-fg\fR, \fB\-\-foreground \fIcolor\fR +Sets the default foreground color. +.TP +.B \-\-btn\fR, \fB\-\-button \fIcolor\fR +Sets the default button color. +.TP +.B \-\-name \fIname\fR +Sets the application name. +.TP +.B \-\-title \fItitle\fR +Sets the application title (caption). +.TP +.B \-\-visual TrueColor +Forces the application to use a TrueColor visual on +an 8\-bit display. +.TP +.B \-\-inputstyle \fIinputstyle\fR +Sets XIM (X Input Method) input style. Possible +values are onthespot, overthespot, offthespot and +root. +.TP +.B \-\-im \fIXIM server\fR +Set XIM server. +.TP +.B \-\-noxim +Disable XIM. +.TP +.B \-\-reverse +Mirrors the whole layout of widgets. +.SS KDE options: +.TP +.B \-\-caption \fIcaption\fR +Use 'caption' as name in the titlebar. +.TP +.B \-\-icon \fIicon\fR +Use 'icon' as the application icon. +.TP +.B \-\-miniicon \fIicon\fR +Use 'icon' as the icon in the titlebar. +.TP +.B \-\-config \fIfilename\fR +Use alternative configuration file. +.TP +.B \-\-dcopserver \fIserver\fR +Use the DCOP Server specified by 'server'. +.TP +.B \-\-nocrashhandler +Disable crash handler, to get core dumps. +.TP +.B \-\-waitforwm +Waits for a WM_NET compatible windowmanager. +.TP +.B \-\-style \fIstyle\fR +Sets the application GUI style. +.TP +.B \-\-geometry \fIgeometry\fR +Sets the client geometry of the main widget. +.SH INTERFACE +.SS Browse and View modes +By default, Gwenview opens in Browse mode, with the docked windows (showing +directory structure and contents) displayed. Starting Gwenview with a directory +as an argument also begins in Browse mode. Starting with an image as an argument, +however, opens Gwenview in View mode, with these docked windows hidden to give +full space to the image itself. +.PP +Once Gwenview is started, the user can toggle between Browse and View modes by +clicking the Browse button on the Main Toolbar. The same option can be found +in the View menu. Ctrl-Return will toggle these modes as well. +.PP +Whereas normally, in Browse mode, single-clicking on an image thumbnail or +listing is sufficient for Gwenview to display it, users also have the option of +double-clicking, which displays the image and switches Gwenview to View mode. +.SS Docked windows +The Gwenview interface is composed of a number of smaller docked windows. +Manipulating these windows can be difficult at first. To focus a particular +window in the Gwenview interface, simply click within it. +.PP +Each docked window has a small grip bar along the top, with a dock/undock button +resembling an arrow at its right end, as well as a close button resembling the +letter X. +.PP +Clicking the close button on a docked window will remove it from the interface. +To bring back a window, select it from the Window menu. +.PP +To resize docked windows, click on the border between the windows, and drag. +To re-arrange the docked windows, click on a window's grip bar along its top, and drag +the window over to the desired position relative to the other docked windows. +While dragging, a small box outline should appear that indicates the new position +that the window will take, when you release the mouse and end the drag. If you wish +to stack two windows, and use tabs to choose between them, drag the window to the +very center of the other window with which you wish to stack. +.PP +To undock a window, either click the dock/undock button in its top right corner, or +double-click on the window's grip bar. Double-clicking again, or clicking +on the dock/undock button, should return the window to its original position. +Otherwise, you can dock an undocked window by dragging its grip bar back to a +point within the general interface, just as if you were rearranging an already +docked window. +.PP +The file view window cannot be undocked or moved, but by moving other windows +around, it can itself be shifted about. +.PP +While dragging a window, press the Escape key to cancel the operation. To reset +the docked windows to the default Gwenview layout, use the Reset option in the +Window menu. +.SS Mouse operations +Browsing a directory of images can be done several ways, including mouse +gestures. Hold down the left mouse button over an image, then click the right +button to go to the next image. Hold down the right button, then click the +left button to load the previous image. +.PP +Clicking the right mouse button on an image brings up a context menu. +.PP +Clicking the middle mouse button will toggle the auto zoom on/off. +.PP +Double-clicking on an image toggles Full Screen mode. +.PP +Holding down the left mouse button on an image allows you to +scroll the image. By default, you can also scroll up and down an image by +using the mouse wheel. However, this can be configured to browse the images +in the current directory instead. +.PP +The mouse wheel, used while holding down the Shift key, will zoom the image +in and out. +.PP +The mouse wheel, used while holding down the Control or Alt keys, will scroll the image horizontally. +.SS Keybindings +Gwenview comes with a range of keyboard shortcuts, all of which can be viewed and remapped by +selecting "Configure Shortcuts" in the Settings menu. Note that in the Files and Folders windows, +all the normal KDE shortcuts are functional, unless otherwise remapped. +.PP +A few of the most useful default bindings are: +.PP + Ctrl-Shift-F Toggles Full Screen mode. + Escape Stop, exit from Full Screen mode. + + Home Displays the first image in the directory. + End Displays the last image in the directory. + + Space Displays the next image in the directory. + Backspace Displays the previous image in the directory. +.SH "SEE ALSO" +The Gwenview homepage can be found at \fIhttp://gwenview.sourceforge.net\fR. +.PP +A mailing list is also available at \fIhttp://lists.sourceforge.net/lists/listinfo/gwenview-general\fR. +.SH BUGS +To report a bug, please visit \fIhttp://bugs.kde.org\fR. +.SH AUTHOR +Gwenview was written by Aurelien Gateau <aurelien.gateau@free.fr>. +.PP +This manual page was written by Christopher Martin <chrsmrtn@debian.org> for +Debian GNU/Linux, but may be used by others. +.PP +Permission is granted to copy, distribute and/or modify this document under the +terms of the GNU General Public License, Version 2, any later version published +by the Free Software Foundation. diff --git a/src/gvcore/.vimrc b/src/gvcore/.vimrc new file mode 100644 index 0000000..a37475c --- /dev/null +++ b/src/gvcore/.vimrc @@ -0,0 +1,4 @@ +set tabstop=4 +set shiftwidth=4 +set noexpandtab +set makeprg=unsermake diff --git a/src/gvcore/Makefile.am b/src/gvcore/Makefile.am new file mode 100644 index 0000000..1bec46b --- /dev/null +++ b/src/gvcore/Makefile.am @@ -0,0 +1,85 @@ +AM_CPPFLAGS = -I$(srcdir)/.. $(all_includes) -D_LARGEFILE64_SOURCE + +lib_LTLIBRARIES = libgwenviewcore.la + +libgwenviewcore_la_LDFLAGS = $(all_libraries) -version-info 1:0:0 -no-undefined + +libgwenviewcore_la_LIBADD = \ + $(LIB_KFILE) $(LIB_KDEUI) $(LIB_KDECORE) $(LIB_KDEPRINT) $(LIB_QT) \ + $(LIBJPEG) $(LIBPNG) $(LIBMNG) $(GV_LIB_XCURSOR) $(LIB_EXIV2)\ + -lkmediaplayer ../imageutils/libgvimageutils.la \ + ../tsthread/libtsthread.la + +libgwenviewcore_la_METASOURCES = AUTO + +noinst_HEADERS = libgwenview_export.h + +# Be sure to keep pngformattype.cpp first, to avoid troubles with --enable-final +# See bug #134919 +libgwenviewcore_la_SOURCES = \ + pngformattype.cpp \ + printdialog.cpp \ + printdialogpagebase.ui \ + thumbnailloadjob.cpp \ + imageview.cpp \ + imageviewcontroller.cpp \ + document.cpp \ + externaltoolmanager.cpp \ + externaltoolcontext.cpp \ + externaltoolaction.cpp \ + externaltooldialogbase.ui \ + externaltooldialog.cpp \ + fileviewcontroller.cpp \ + filethumbnailview.cpp \ + fileoperation.cpp \ + fileopobject.cpp \ + filethumbnailviewitem.cpp \ + filterbar.ui \ + qxcfi.cpp \ + archive.cpp \ + slideshow.cpp \ + filedetailview.cpp \ + filedetailviewitem.cpp \ + imagesavedialog.cpp \ + jpegformattype.cpp \ + mngformattype.cpp \ + xpm.cpp \ + documentimpl.cpp \ + documentloadingimpl.cpp \ + documentloadedimpl.cpp \ + documentjpegloadedimpl.cpp \ + documentanimatedloadedimpl.cpp \ + documentotherloadedimpl.cpp \ + busylevelmanager.cpp \ + cache.cpp \ + threadgate.cpp \ + imageviewtools.cpp \ + fullscreenbar.cpp \ + imageloader.cpp \ + cursortracker.cpp \ + captionformatter.cpp \ + thumbnaildetailsdialogbase.ui \ + thumbnaildetailsdialog.cpp \ + xcursor.cpp \ + mimetypeutils.cpp \ + bcgdialog.cpp \ + bcgdialogbase.ui \ + timeutils.cpp \ + clicklineedit.cpp \ + inputdialog.cpp \ + deletedialog.cpp \ + deletedialogbase.ui \ + miscconfig.kcfgc \ + slideshowconfig.kcfgc \ + fileoperationconfig.kcfgc \ + fullscreenconfig.kcfgc \ + imageviewconfig.kcfgc \ + fileviewconfig.kcfgc + +kde_kcfg_DATA = \ + miscconfig.kcfg \ + slideshowconfig.kcfg \ + fileoperationconfig.kcfg \ + fullscreenconfig.kcfg \ + imageviewconfig.kcfg \ + fileviewconfig.kcfg diff --git a/src/gvcore/archive.cpp b/src/gvcore/archive.cpp new file mode 100644 index 0000000..d31d1a7 --- /dev/null +++ b/src/gvcore/archive.cpp @@ -0,0 +1,87 @@ +// vim: set tabstop=4 shiftwidth=4 noexpandtab +/* +Gwenview - A simple image viewer for KDE +Copyright 2000-2004 Aurlien Gteau + +This program is free software; you can redistribute it and/or +modify it under the terms of the GNU General Public License +as published by the Free Software Foundation; either version 2 +of the License, or (at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Both the source and destination virtual arrays are allocated from the + * source JPEG object, and therefore should be manipulated by calling the + * source's memory manager. + * 2.

When + * forcing to grayscale the destination's sampling factors will be all 1, + * and we may as well take that as the effective iMCU size. + * 4. When "trim" is in effect, the destination's dimensions will be the + * trimmed values but the source's will be untrimmed. + * 5. All the routines assume that the source and destination buffers are + * padded out to a full iMCU boundary.

So, we have to exclude any partial iMCUs from the + * basic transformation. + * + * Transpose is the only transformation that can handle partial iMCUs at the + * right and bottom edges completely cleanly. flip_h can flip partial iMCUs + * at the bottom, but leaves any partial iMCUs at the right edge untouched. + * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched. + * The other transforms are defined as combinations of these basic transforms + * and process edge blocks in a way that preserves the equivalence. + * + * The "trim" option causes untransformable partial iMCUs to be dropped; + * this is not strictly lossless, but it usually gives the best-looking + * result for odd-size images. Note that when this option is active, + * the expected mathematical equivalences between the transforms may not hold. + * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim + * followed by -rot 180 -trim trims both edges.) + * + * We also offer a "force to grayscale" option, which simply discards the + * chrominance channels of a YCbCr image. This is lossless in the sense that + * the luminance channel is preserved exactly. It's not the same kind of + * thing as the rotate/flip transformations, but it's convenient to handle it + * as part of this package, mainly because the transformation routines have to + * be aware of the option to know how many components to work on. + */ + +typedef struct { + /* Options: set by caller */ + JXFORM_CODE transform; /* image transform operator */ + boolean trim; /* if TRUE, trim
