Deconstruct apng file into a sequence of png frames
Extract invividual \s-1PNG\s0 files from animated \s-1PNG\s0.
After editing \s-1PNG\s0 frames in programs like Photoshop or \s-1GIMP\s0, you can assemle files back into \s-1APNG\s0 using apngasm\|(1). Crrectly handles all blend/dispose combinations, in all color modes/depths.
Some optimizations used in apngasm\|(1) might re-sort the palette, or change the color type from \s-1RGBA\s0 and \s-1RGB\s0 modes to \s-1RGB\s0 and indexed modes. Those optimizations are only performed when they are lossless, but if you want to avoid changing the palette or colortype, see options to turn them off.
The Animated Portable Network Graphics (\s-1APNG\s0) file format is an extension to the Portable Network Graphics (\s-1PNG\s0) specification. It allows for animated \s-1PNG\s0 files that work similarly to animated \s-1GIF\s0 files, while retaining backward compatibility with non-animated \s-1PNG\s0 files and adding support for 8-bit transparency and 24-bit images.
