gifencoder 0.2.1

A library for creating gif files, including animated gifs.

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

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

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.
