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

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### 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 an `SkPicture`, which can be dumped to disk (for debugging) with
   `SkPicture.DEBUGONLY_saveAsFile`.

### 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` to `SkImage.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 function `SkTextBlob.MakeOnPath`.
 - `SkSurface.requestAnimationFrame` - wrapper around window.requestAnimationFrame that
   takes care of the setup/tear down required to use CanvasKit optimally. The callback
   has an `SkCanvas` as the first parameter - callers should draw on that.

### 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.
 - 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 call `SkSurface.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()` 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.
