NAME

       apngdis - deconstruct APNG file into a sequence of PNG frames

SYNOPSIS

       apngdis filename.png [name]

DESCRIPTION

       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.
