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
SkSurface.drawOnce
for drawing a single frame (in addition to already existingSkSurface.requestAnimationFrame
for animation logic).
[0.12.0] - 2020-01-22
Added
SkFontMgr.countFamilies
andSkFontMgr.getFamilyName
to expose the parsed font names.
Changed
- SKP serialization/deserialization now available (can be disabled with the 'no_skp').
SkPicture.DEBUGONLY_saveAsFile
renamed toSkPicture.saveAsFile
andCanvasKit.MakeSkPicture
is now exposed. SKP support is not shipped to npm builds.force_serialize_skp
has been removed since it opt-out, not opt-in.
Fixed
- Bug that sometimes resulted in 'Cannot perform Construct on a neutered ArrayBuffer'
- Bug with SkImage.readPixels (skbug.com/9788)
- Bug with transparent colors in Canvas2d mode (skbug.com/9800)
[0.11.0] - 2020-01-10
Added
- A "Core" build that removes Fonts, the Skottie animation player, the Particles demo,
and PathOps is available in
bin/core/
. It is about half the size of the "CoreWithFonts" build. - Experimental Runtime shader available for custom builds.
- WebP support.
SkAnimatedImage.getCurrentFrame
which returns an SkImage.
Fixed
CanvasKit.SaveLayerInitWithPrevious
andCanvasKit.SaveLayerF16ColorType
constants.- Some compilation configurations, for example, those with no fonts or just one of particles/skottie.
Changed
- Small tweaks to compilation settings to reduce code size and linkage time.
- JS functions are no longer provided when the underlying c++ calls have been compiled out.
Removed
SkShader.Empty
- Support for Type 1 Fonts. These are ancient and removing them saves about 135k of code size.
Breaking
- In an effort to reduce code size for most clients, npm now contains two CanvasKit builds.
In
bin/
there is the "CoreWithFonts" build that contains most functionality from 0.10.0. However, we no longer ship the Skottie animation player, nor the Particles demo. Further, PathOps are removed from this buildMakePathFromOp
,SkPath.op
andSkPath.simplify
. Clients who need any of those features are encouraged to create a custom build usingcompile.sh
. SkPicture.DEBUGONLY_saveAsFile
was accidentally included in release builds. It has been removed. Clients who need this in a release build (e.g. to file a bug report that only reproduces in release) should do a custom build with theforce_serialize_skp
flag given.
Deprecated
SkCanvas.drawAnimatedImage
will be renamed soon. Calls can be replaced withSkCanvas.drawImage
andSkAnimatedImage.getCurrentFrame
.
[0.10.0] - 2019-12-09
Added
SkContourMeasureIter
andSkContourMeasure
as an alternative toSkPathMeasure
.- CanvasKit image decode cache helpers: getDecodeCacheLimitBytes(), setDecodeCacheLimitBytes(), and getDecodeCacheUsedBytes().
SkShader.Blend
,SkShader.Color
,SkShader.Empty
,SkShader.Lerp
.
Changed
- The returned values from
SkParagraph.getRectsForRange
now have direction with valueCanvasKit.TextDirection
.
Fixed
MakeImage
properly in the externs file and can work withCanvasKit.Malloc
.
[0.9.0] - 2019-11-18
Added
- Experimental
CanvasKit.Malloc
, which can be used to create a TypedArray backed by the C++ WASM memory. This can save a copy in some cases (e.g. SkColorFilter.MakeMatrix). This is an advanced feature, so use it with care. SkCanvas.clipRRect
,SkCanvas.drawColor
- Blur, ColorFilter, Compose, MatrixTransform SkImageFilters. Can be used with
SkPaint.setImageFilter
. SkCanvas.saveLayer
now takes 3 or 4 params to include up to bounds, paint, SkImageFilter, flags.SkPath.rArcTo
,SkPath.rConicTo
,SkPath.rCubicTo
,SkPath.rLineTo
,SkPath.rMoveTo
,SkPath.rQuadTo
. Like their non-relative siblings, these are chainable.- Add
width()
,height()
,reset()
,getFrameCount()
to SkAnimatedImage. SkCanvas.drawImageNine
,SkCanvas.drawPoints
and relatedPointMode
enum.SkPath.addPoly
SkPathMeasure.getSegment
- More information on SkParagraph API, eg.
getLongestLine()
,getWordBoundary
, and others.
Deprecated
CanvasKit.MakeBlurMaskFilter
will be renamed/moved soon toCanvasKit.SkMaskFilter.MakeBlur
.
Changed
- Use newer version of Freetype2 (Tracking Skia's DEPS now).
- Use newer versions of libpng and zlib (Tracking Skia's DEPS now).
Fixed
- null dereference when sometimes falling back to CPU.
- Actually ask WebGL for a stencil buffer.
- Can opt out of Paragraph API with no_paragraph passed into compile.sh or when using primitive_shaper.
[0.8.0] - 2019-10-21
Added
CanvasKit.MakeAnimatedImageFromEncoded
,SkCanvas.drawAnimatedImage
.CanvasKit.SkFontMgr.FromData
which takes several ArrayBuffers of font data, parses them, reading the metadata (e.g. family names) and stores them into a SkFontMgr.- SkParagraph as an optional set of APIs for dealing with text layout.
Changed
- The
no_font
compile option should strip out more dead code related to fonts. - and
no_embedded_font
option now allows creating aSkFontMgr.FromData
instead of always having an empty one. - Updated to emscripten 1.38.47
- Switch to WebGL 2.0, but fall back to 1.0 when unavailable - bug.skia.org/9052
Fixed
- Null terminator bug in draw text - skbug.com/9314
[0.7.0] - 2019-09-18
Added
SkCanvas.drawCircle()
,SkCanvas.getSaveCount()
SkPath.offset()
,SkPath.drawOval
SkRRect
support (SkCanvas.drawRRect
,SkCanvas.drawDRRect
,CanvasKit.RRectXY
). Advanced users can specify the 8 individual radii, if needed.CanvasKit.computeTonalColors()
, which returns TonalColors, which has an ambient SkColor and a spot SkColor.CanvasKit.SkColorFilter
and a variety of factories.SkPaint.setColorFilter
is the only consumer of these at the moment.CanvasKit.SkColorMatrix
with functions.identity()
,.scaled()
,.concat()
and others. Primarily for use withCanvasKit.SkColorFilter.MakeMatrix
.
Changed
MakeSkVertices
uses a builder to save a copy.
Breaking
- When
SkPath.arcTo
is given seven arguments, it no longer turns the first four into aSkRect
automatically, and instead uses them asarcTo(rx, ry, xAxisRotate, useSmallArc, isCCW, x, y)
(see SkPath.h for more).
[0.6.0] - 2019-05-06
Added
SkSurface.grContext
now exposed.GrContext
has new methods for monitoring/setting the cache limits; tweaking these may lead to better performance in some cases.getResourceCacheLimitBytes
,setResourceCacheLimitBytes
,getResourceCacheUsageBytes
SkCanvas.drawAtlas
for efficiently drawing multiple sprites from a sprite sheet with a set of transforms, color blends, etc.SkColorBuilder
,RSXFormBuilder
,SkRectBuilder
which increase performance by reducing the amount of malloc/free calls per frame, given that the array size is fixed.- Basic
SkPicture
support.SkSurface.captureFrameAsSkPicture
is a helper function to capture anSkPicture
, which can be dumped to disk (for debugging) withSkPicture.DEBUGONLY_saveAsFile
. SkImage.readPixels
, which returns a TypedArray of pixel values (safe to use anywhere, doesn't need a delete()).
Changed
- Better
GrGLCaps
support for WebGL - this shouldn't have any impacts on APIs or correctness, except by perhaps fixing a few bugs in various surface types. - Use unsigned ints for SkColor on the JS side - this shouldn't have any impacts unless clients have pre-computed colors, in which case, they will need to re-compute them.
- [breaking] Moved
CanvasKit.MakeImageShader
toSkImage.makeShader
- removed clampUnpremul as argument.
[0.5.1] - 2019-03-21
Added
SkPathMeasure
,RSXFormBuilder
,SkFont.getWidths
,SkTextBlob.MakeFromRSXform
which were needed to add the helper functionSkTextBlob.MakeOnPath
.SkSurface.requestAnimationFrame
- wrapper around window.requestAnimationFrame that takes care of the setup/tear down required to use CanvasKit optimally. The callback has anSkCanvas
as the first parameter - callers should draw on that.
Changed
- Location in Skia Git repo now
modules/canvaskit
(wasexperimental/canvaskit
)
Fixed
- 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.
- Antialias bug on large oval paths https://crbug.com/skia/8873
Deprecated
SkCanvas.flush
will be removed soon - client should only callSkSurface.flush
[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()
andSkCanvas.getSurface()
for making compatible surfaces (typically used as a workspace and then "saved" withsurface.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 theSkSurface
themselves withGetWebGLContext
->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
andSkPath.toCmds
. SkCanvas.drawTextBlob()
andSkCanvas.SkTextBlob.MakeFromText()
to draw text to a canvas.CanvasKit.TextEncoding
enum. For use withSkTextBlob
.- Text shaping with
ShapedText
object andSkCanvas.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 anSkFont
object for raw strings.
Removed
SkPaint.setTextSize()
,SkPaint.getTextSize()
,SkPaint.setTypeface()
which should be replaced by usingSkFont
.- 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. UseCanvasKitInit(...).ready()
, which returns a real Promise.
Removed
SkPaint.measureText
- useSkFont.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 thecompile.sh
invocation. CanvasKit.FontMgr.DefaultRef()
andfontmgr.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 anSkImage
, created fromCanvasKit.MakeImageFromEncoded
. Additionally, the optional parametersclampIfUnpremul
andlocalMatrix
have been exposed.SkPath.arcTo
now takesstartAngle
,sweepAngle
,forceMoveTo
as additional parameters.SkPath.stroke
has a new optionprecision
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
