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]

Added

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

Changed

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

Fixed

• Extern bug in CanvasKit.SkMatrix.invert
• Fallback to CPU now properly refreshes the canvas to get access to the CanvasRenderingContext2D.

[0.5.0] - 2019-03-08

Added

• 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())

Breaking

• 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.

[0.4.1] - 2019-03-01

Added

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

[0.4.0] - 2019-02-25

Added

• 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).

Changed

• SkCanvas.drawText() now requires an SkFont object for raw strings.

Removed

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

Fixed

• Potential bug in ready() if already loaded.

[0.3.1] - 2019-01-04

Added

• 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.

Changed

• 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.

Removed

• SkPaint.measureText - use SkFont.measureText instead.

[0.3.0] - 2018-12-18

Added

• 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.

Fixed

• SkPath.addRect now correctly draws counter-clockwise vs clockwise.

Changed

• 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.

Removed

• CanvasKit.initFonts() - no longer needed.

[0.2.1] - 2018-11-20
