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.
