Fixed:

• Rendering issues when scrolling vertically and/or drawing inside the border area prior to scrolling (thanks hcs64)

Improved:

• Added a "Show content bounds" option to the demo that draws a green rectangle indicating the reported contentBounds coordinates for each frame

v6 is a major change making the library significantly smaller and more flexible. Please see the README for updated example usage.

• Instead of drawing to a canvas, render() now simply returns an ImageData object along with some metadata. This gives full control over your canvas (if a canvas is used at all!)
• The onBackgroundChange callback is removed; instead, check the backgroundRGBA metadata provided with each rendered frame
• The setOptions() method is removed, as options are now arguments to render()
• When loading a file, you now only need to pass the ArrayBuffer of the response (the creation of the new Uint8Array is handled internally)

Improved:

• Instructions are now processed JIT, significantly reducing load() time
• Added contentBounds metadata describing a bounding box that fits the rendered frame's non-transparent content

Breaking changes/migrating from 4.x:

v5 has a new, simple API. Instead of play(), pause() and syncTime(), you now control the requestAnimationFrame loop and render() a frame at the currentTime. This also enables full rewind/random seek support. See the README for more on using render().

Breaking changes/migrating from 3.x:

• The forceTransparent option has been renamed forceKey. Subsequently, the forceTransparent() method has been removed, and forceKey can be set with the new setOptions() method.

Improved:

• Added shadow effects support
• Significantly reduced CPU usage during idle frames

Breaking changes/migrating from 2.x:

• Internet Explorer, Chrome < v30, and Firefox < v51 are no longer officially supported (removed vendor prefixes for imageSmoothingEnabled)
• The stop() method has been renamed pause()
• The sync() method has been replaced with syncTime() and now expects a time in seconds (instead of ms)

Improved:

• Graphics now scale fluidly with the canvas instead of at fixed increments
• Canvas no longer temporarily appears blurry while resizing

• Improved documentation

• Major performance improvements from offscreen canvas rendering
• Added experimental forceTransparent option and callback for background color changes
• Improved docs
• Improved demo
• Updated dev dependencies

Breaking Changes

• Requires ES2015 (or later) environment
