apng2gif - convert APNG animated images to GIF files
apng2gif <INPUT *.png> <OUTPUT *.gif> [options]
Progrmam apng2gif converts APNG into animated GIF format.
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.
Default run values are /t 128, no background color. A short syntax help is
provided without any command line arguments.
- /b COLOR
- 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 LEVEL
- Transparency threshold level between 0..155. Default is
128. pixels with alpha level less than 128 will become fully
transparent.
