CanvasKit Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

SkPathMeasure, RSXFormBuilder, SkFont.getWidths, SkTextBlob.MakeFromRSXform which were needed to add the helper function SkTextBlob.MakeOnPath.

Location in Skia Git repo now modules/canvaskit (was experimental/canvaskit)

Extern bug in CanvasKit.SkMatrix.invert
Fallback to CPU now properly refreshes the canvas to get access to the CanvasRenderingContext2D.
Compile flags for better WebGL1 support for some graphics cards.

SkCanvas.flush will be removed soon - client should only call SkSurface.flush

isVolitile option to CanvasKit.MakeSkVertices. The previous (and current default) behavior was for this to be true; some applications may go faster if set to false.
SkCanvas.saveLayer(rect, paint)
SkCanvas.restoreToCount(int) which can be used with the output of .save() and .saveLayer().
Optional particles library from modules/particles. See CanvasKit.MakeParticles(json);
More public APIs for working with Surfaces/Contexts GetWebGLContext, MakeGrContext, MakeOnScreenGLSurface, MakeRenderTarget.
SkSurface.getSurface() and SkCanvas.getSurface() for making compatible surfaces (typically used as a workspace and then “saved” with surface.makeImageSnapshot())

CanvasKit.MakeWebGLCanvasSurface no longer takes a webgl context as a first arg, only a canvas or an id of a canvas. If users want to manage their own GL contexts, they should build the SkSurface themselves with GetWebGLContext -> MakeGrContext -> MakeOnScreenGLSurface.

Optional arguments to MakeManagedAnimation for supplying external assets (like images, fonts).

SkPath.addRoundRect, SkPath.reset, SkPath.rewind exposed.
SkCanvas.drawArc, SkCanvas.drawLine, SkCanvas.drawOval, SkCanvas.drawRoundRect exposed.
Can import/export a SkPath to an array of commands. See CanvasKit.MakePathFromCmds and SkPath.toCmds.
SkCanvas.drawTextBlob() and SkCanvas.SkTextBlob.MakeFromText() to draw text to a canvas.
CanvasKit.TextEncoding enum. For use with SkTextBlob.
Text shaping with ShapedText object and SkCanvas.drawText. At compile time, one can choose between using Harfbuzz/ICU (default) or a primitive one (“primitive_shaper”) which just does line breaking. Using Harfbuzz/ICU substantially increases code size (4.3 MB to 6.4 MB).

SkPaint.setTextSize(), SkPaint.getTextSize(), SkPaint.setTypeface() which should be replaced by using SkFont.
Deprecated CanvasKitInit().then() interface (see 0.3.1 notes)

SkFont now exposed.
MakeCanvasSurface can now take a canvas element directly.
MakeWebGLCanvasSurface can now take a WebGL context as an integer and use it directly.

CanvasKitInit(...).then() is no longer the recommended way to initialize things. It will be removed in 0.4.0. Use CanvasKitInit(...).ready(), which returns a real Promise.

Add Canvas2D JS layer. This mirrors the HTML Canvas API. This may be omitted at compile time it by adding no_canvas to the compile.sh invocation.
CanvasKit.FontMgr.DefaultRef() and fontmgr.MakeTypefaceFromData to load fonts.
Exposed SkPath.setVolatile. Some animations see performance improvements by setting their paths' volatility to true.

CanvasKit.MakeImageShader no longer takes encoded bytes, but an SkImage, created from CanvasKit.MakeImageFromEncoded. Additionally, the optional parameters clampIfUnpremul and localMatrix have been exposed.
SkPath.arcTo now takes startAngle, sweepAngle, forceMoveTo as additional parameters.
SkPath.stroke has a new option precision It defaults to 1.0.
CanvasKit comes with one font (NotoMono) instead of the Skia TestTypeface. Clients are encouraged to use the new fontmgr.MakeTypefaceFromData for more font variety.
