Detailed Description

+ + +The TQPNGImagePacker class creates well-compressed PNG animations. +

+ +

By using transparency, TQPNGImagePacker allows you to build a PNG +image from a sequence of TQImages. +

Images are added using packImage(). +

Member Function Documentation

+

TQPNGImagePacker::TQPNGImagePacker ( TQIODevice * 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 TQt::ImageConversionFlags. + +

bool TQPNGImagePacker::packImage ( const TQImage & img ) +

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

void TQPNGImagePacker::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. + + +
