+.SH DESCRIPTION
+The QPNGImagePacker class creates well-compressed PNG animations.
+.PP
+By using transparency, QPNGImagePacker allows you to build a PNG image from a sequence of QImages.
+.PP
+Images are added using packImage().
+.PP
+See also Graphics Classes and Image Processing Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QPNGImagePacker::QPNGImagePacker ( QIODevice * iod, int storage_depth, int conversionflags )"
+Creates an image packer that writes PNG data to IO device \fIiod\fR using a \fIstorage_depth\fR bit encoding (use 8 or 32, depending on the desired quality and compression retquirements).
+.PP
+If the image needs to be modified to fit in a lower-resolution result (e.g. converting from 32-bit to 8-bit), use the \fIconversionflags\fR to specify how you'd prefer this to happen.
+.PP
+See also Qt::ImageConversionFlags.
+.SH "bool QPNGImagePacker::packImage ( const QImage & img )"
+Adds the image \fIimg\fR to the PNG animation, analyzing the differences between this and the previous image to improve compression.
+.SH "void QPNGImagePacker::setPixelAlignment ( int x )"
+Aligns pixel differences to \fIx\fR pixels. For example, using 8 can
+improve playback on certain hardware. Normally the default of
+1-pixel alignment (i.e. no alignment) gives better compression and
+performance.
