apngdis - deconstruct APNG file into a sequence of PNG frames
Extract invividual PNG files from animated PNG.
After editing PNG frames in programs like Photoshop or GIMP, you can assemle
files back into APNG 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 RGBA and RGB modes to RGB 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 (APNG) file format is an extension to the
Portable Network Graphics (PNG) specification. It allows for animated PNG
files that work similarly to animated GIF files, while retaining backward
compatibility with non-animated PNG files and adding support for 8-bit
transparency and 24-bit images.
