API

apng2gif(inputPath[, outputPath[, options]]) => Promise

Convert the animated PNG at inputPath to GIF and write it to outputPath. Returns a Promise which is resolved when outputPath exists.

If outputPath is omitted, it defaults to inputPath but with .gif extension.

options

• backgroundColor - Background color string to blend semi-transparent pixels with (#rrggbb format).
• transparencyThreshold - Threshold against which to omit transparent pixels (0-256).

You may also pass any valid child_process.spawn options, notably:

• cwd - Directory to run apng2gif in

apng2gif.sync(inputPath[, outputPath[, options]]) => undefined

Synchronously convert the animated PNG at inputPath to GIF and write it to outputPath.

If outputPath is omitted, it defaults to inputPath but with .gif extension.

options

• backgroundColor - Background color string to blend semi-transparent pixels with (#rrggbb format).
• transparencyThreshold - Threshold against which to omit transparent pixels (0-256).

You may also pass any valid child_process.spawnSync options, notably:

• cwd - Directory to run apng2gif in
