apng2gif <INPUT *.png> <OUTPUT *.gif> [options]


Progrmam apng2gif converts \s-1APNG\s0 into animated \s-1GIF\s0 format.

The Animated Portable Network Graphics (\s-1APNG\s0) file format is an extension to the Portable Network Graphics (\s-1PNG\s0) specification. It allows for animated \s-1PNG\s0 files that work similarly to animated \s-1GIF\s0 files, while retaining backward compatibility with non-animated \s-1PNG\s0 files and adding support for 8-bit transparency and 24-bit images.

Default run values are /t 128, no background color. A short syntax hlp is provided without any command line arguments.


/b \s-1COLOR\s0

Background blend color. Format: #RGB in hex, like #808080, or three values in decimal. Like: 128 128 128. If this option is used, option /t is ignored With option: /b #ff0000 or /b 255 0 0 will set the background color as red, so partially transparent pixels will be composed over red.

/t \s-1LEVEL\s0

Transparency threshold level between 0..155. Default is 128. pixels with alpha level less than 128 will become fully transparent.
