NAME

       apng2gif -  convert APNG animated images to GIF files

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       /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.
