Methods

MakeBlend(
mode: BlendMode,
one: Shader,
two: Shader,
): Shader

Returns a shader that combines the given shaders with a BlendMode.

MakeColor(color: InputColor, space: ColorSpace): Shader

Returns a shader with a given color and colorspace.

MakeFractalNoise(
baseFreqX: number,
baseFreqY: number,
octaves: number,
seed: number,
tileW: number,
tileH: number,
): Shader

Returns a shader with Perlin Fractal Noise. See SkPerlinNoiseShader.h for more details

MakeLinearGradient(
start: InputPoint,
pos: number[] | null,
mode: TileMode,
localMatrix?: InputMatrix,
flags?: number,
colorSpace?: ColorSpace,
): Shader

Returns a shader that generates a linear gradient between the two specified points. See SkGradientShader.h for more.

center: InputPoint,
radius: number,
pos: number[] | null,
mode: TileMode,
localMatrix?: InputMatrix,
flags?: number,
colorSpace?: ColorSpace,
