1 The Animated Portable Network Graphics (APNG) file format is an extension to
2 the Portable Network Graphics (PNG) specification. It allows for animated PNG
3 files that work similarly to animated GIF files, while retaining backward
4 compatibility with non-animated PNG files and adding support for 8-bit
5 transparency and 24-bit images.
