Interfaces
An opaque object describing a gradient. It is returned by the methods CanvasRenderingContext2D.createLinearGradient() or CanvasRenderingContext2D.createRadialGradient(). | |
An opaque object describing a pattern, based on an image, a canvas, or a video, created by the CanvasRenderingContext2D.createPattern() method. | |
The CanvasRenderingContext2D export interface, part of the Canvas API, provides the 2D rendering context for the drawing surface of a element. It is used for drawing shapes, text, images, and other objects. | |
The currently supported color spaces. These are all singleton values. | |
Represents the set of enum values. | |
Represents a single member of an enum. | |
CanvasKit is built with Emscripten and Embind. Embind adds the following methods to all objects that are exposed with it. | |
See GrContext.h for more on this class. | |
A constructor for making an ImageData that is compatible with the Canvas2D emulation code. | |
This object is a wrapper around a pointer to some memory on the WASM heap. The type of the pointer was determined at creation time. | |

Options used for SkPath.stroke(). If an option is omitted, a sensible default will be used. | |
Functions for manipulating vectors. It is Loosely based off of SkV3 in SkM44.h but Skia also has SkVec2 and Skv4. This combines them and works on vectors of any length. | |
Options for configuring a WebGL context. If an option is omitted, a sensible default will be used. These are defined by the WebGL standards. |
Type Aliases
Part of the Canvas2D emulation code | |
FlattenedPointArray represents n points by 2*n float values. In order, the values should be the x, y for each point. | |
FlattenedRectangleArray represents n rectangles by 4*n float values. In order, the values should be the top, left, right, bottom point for each rectangle. | |
Regardless of the format we use internally for GlyphID (16 bit unsigned atm), we expose them as 32 bit unsigned. | |

CanvasKit APIs accept normal arrays, typed arrays, or Malloc'd memory as rectangles with rounded corners. Length 12. | |
PathCommand contains a verb and then any arguments needed to fulfill that path verb. Examples: [CanvasKit.MOVE_VERB, 0, 10] [CanvasKit.LINE_VERB, 30, 40] TODO(kjlubick) Make this not be a 2-d array and support typed arrays. | |
A PosTan is an array of 4 values, representing a position and a tangent vector. In order, the values are [px, py, tx, ty]. | |
An SkColor is represented by 4 floats, typically with values between 0 and 1.0. In order, the floats correspond to red, green, blue, alpha. | |
See SkColorFilter.h for more on this class. The objects are opaque. | |
An SkColorMatrix is a 4x4 color matrix that transforms the 4 color channels with a 1x4 matrix that post-translates those 4 channels. For example, the following is the layout with the scale (S) and post-transform (PT) items indicated. RS, 0, 0, 0 | RPT 0, GS, 0, 0 | GPT 0, 0, BS, 0 | BPT 0, 0, 0, AS | APT | |
