A gif encoder written in Dart.

Usage

To create a regular GIF:

import 'dart:html'; import 'package:gifencoder/gifencoder.dart';

int width = ...; int height = ...; var ctx = new CanvasElement(width: width, height: height).context2D; // draw your image in the canvas context var data = ctx.getImageData(0, 0, width, height); List<int> bytes = gifencoder.makeGif(width, height, data.data)

To create an animated Gif, use a GifBuffer instead:

int framesPerSecond = ...; var frames = new gifencoder.GifBuffer(width, height); for (var i = 0; i < myFrameCount; i++) {

// draw the next frame on the canvas context
frames.add(ctx.getImageData(0, 0, width, height).data);

} List<int> bytes = frames.build(framesPerSecond);

Once you have the bytes of the GIF, you can save it somewhere or convert it into a data URL. See example/squares.dart for how to do that.
