Convert animated gif to animated png files

Usage

gif2apng <INPUT *.gif> [<OUTPUT *.png>] [options]

Overview

Progrmam converts animated GIF into animated PNG format. Wu64 quantization is used for true-color files. Transparency is handled either using a threshold, or composed over chosen background color.

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.
