Const composeDest

composeDest: (Anonymous function) = porterDuff((_, d) => d, 1, 0, 1)

Porter-Duff operator. Always results in dest color, src ignored.

see: porterDuff

Const composeDestAtop

composeDestAtop: (Anonymous function) = porterDuff((_, d) => d, 1, 1, 0)

Porter-Duff operator. The destination that overlaps the source is composited with the source and replaces the destination.

see: porterDuff

Const composeDestIn

composeDestIn: (Anonymous function) = porterDuff((_, d) => d, 1, 0, 0)

Porter-Duff operator. The destination that overlaps the source, replaces the source.

see: porterDuff

Const composeDestOut

composeDestOut: (Anonymous function) = porterDuff((_, d) => d, 0, 0, 1)

Porter-Duff operator. The destination that does not overlap the source replaces the source.

see: porterDuff

Const composeDestOver

composeDestOver: (Anonymous function) = porterDuff((_, d) => d, 1, 1, 1)

Porter-Duff operator. The destination color is placed over the source color.

see: porterDuff

Const composeSrc

composeSrc: (Anonymous function) = porterDuff((s) => s, 1, 1, 0)

Porter-Duff operator. Always results in src color, dest ignored.

see: porterDuff

Const composeSrcAtop

composeSrcAtop: (Anonymous function) = porterDuff((s) => s, 1, 0, 1)

Porter-Duff operator. The source that overlaps the destination is composited with the destination.

see: porterDuff

Const composeSrcIn

composeSrcIn: (Anonymous function) = porterDuff((s) => s, 1, 0, 0)

Porter-Duff operator. The source that overlaps the destination, replaces the destination.

see: porterDuff

Const composeSrcOut

composeSrcOut: (Anonymous function) = porterDuff((s) => s, 0, 1, 0)

Porter-Duff operator. The source that does not overlap the destination replaces the destination.

see: porterDuff

Const composeSrcOver

composeSrcOver: (Anonymous function) = porterDuff((s) => s, 1, 1, 1)

Porter-Duff operator. The source color is placed over the destination color.

see: porterDuff

Const composeXor

composeXor: (Anonymous function) = porterDuff(() => 0, 0, 1, 1)

Porter-Duff operator. The non-overlapping regions of source and destination are combined.

see: porterDuff

Functions

Const composeClear

composeClear(out: Color, _: ReadonlyColor, dest: ReadonlyColor): Vec

- Defined in porter-duff.ts:89
Porter-Duff operator. None of the terms are used. Always results in [0, 0, 0, 0].

Parameters
- out: Color
- _: ReadonlyColor
- dest: ReadonlyColor
Returns Vec

Const porterDuff

porterDuff(f: Fn2<number, number, number>, x: 0 | 1, y: 0 | 1, z: 0 | 1): (Anonymous function)

- Defined in porter-duff.ts:27
General Porter-Duff HOF operator for pre-multiplied RGBA. Use porderDiffP for applying pre & post multiplication of input and output colors. The returned function takes 3 arguments:
- out color (if null or undefined writes to dest)
- src color (background)
- dest color (foreground)
Reference: https://drafts.fxtf.org/compositing-1/#advancedcompositing http://www.svgopen.org/2005/papers/abstractsvgopen/#PorterDuffMap
Parameters
- f: Fn2<number, number, number>
  
  blend function
- x: 0 | 1
  
  factor of "both" region
- y: 0 | 1
  
  factor of "src" region
- z: 0 | 1
  
  factor of "dest" region
Returns (Anonymous function)

Const porterDuffP

porterDuffP(out: Color, src: ReadonlyColor, dest: ReadonlyColor, mode: Fn3<Color | null, ReadonlyColor, ReadonlyColor, Color>): Vec

- Defined in porter-duff.ts:68
Like porterDuff, but pre-multiplies alpha for both input colors and then post-multiplies alpha to output.

Parameters
- out: Color
- src: ReadonlyColor
- dest: ReadonlyColor
- mode: Fn3<Color | null, ReadonlyColor, ReadonlyColor, Color>
Returns Vec
