NAME
       QPNGImagePacker - Creates well-compressed PNG animations

SYNOPSIS
       #include <qpngio.h>

   Public Members
       QPNGImagePacker ( QIODevice * iod, int storage_depth, int conversionflags )
       void setPixelAlignment ( int x )
       bool packImage ( const QImage & img )

DESCRIPTION
       The QPNGImagePacker class creates well-compressed PNG animations.

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

       Images are added using packImage().

       See also Graphics Classes and Image Processing Classes.

MEMBER FUNCTION DOCUMENTATION
QPNGImagePacker::QPNGImagePacker ( QIODevice * iod, int storage_depth, int conversionflags )
       Creates an image packer that writes PNG data to IO device iod using a storage_depth bit encoding (use 8 or 32, depending on the desired
       quality and compression requirements).

       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 conversionflags to
       specify how you'd prefer this to happen.

       See also Qt::ImageConversionFlags.

bool QPNGImagePacker::packImage ( const QImage & img )
       Adds the image img to the PNG animation, analyzing the differences between this and the previous image to improve compression.

void QPNGImagePacker::setPixelAlignment ( int x )
       Aligns pixel differences to x 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.
