DESCRIPTION

       Creates well-compressed PNG animations.

       By using transparency, QPNGImagePacker allows you to build
       a PNG image from a sequence of QImages.


MEMBER FUNCTION DOCUMENTATION


QPNGImagePacker::QPNGImagePacker ( QIODevice * iod, int

       storage_depth, int conversionflags )
       Create an image packer that writes PNG data to iod, using
       a storage_depth bit encoding (use 8 or 32, depending on
       the desired quality and compression requirements).


bool QPNGImagePacker::packImage ( const QImage & img )

       Add the image img to the PNG animation, analyzing the
       differences between this and the previous image to improve
       compression.


void QPNGImagePacker::setPixelAlignment ( int x )

       Align pixel differences to x pixels.  For example, using 8
       can improve playback on certain hardware.  Normally the
       default of 1-pixel alignment (ie. no alignment) gives bets
       compression and performance.
