Methods

quantize

quantize(pointContainer: PointContainer, palette: Palette): IterableIterator<ImageQuantizerYieldValue>

Overrides AbstractImageQuantizer.quantize
- Defined in image/array.ts:61
adapted from http://jsbin.com/iXofIji/2/edit by PAEz fixed version. it doesn't use image pixels as error storage, also it doesn't have 0.3 + 0.3 + 0.3 + 0.3 = 0 error Mutates pointContainer

Parameters
- pointContainer: PointContainer
- palette: Palette
Returns IterableIterator<ImageQuantizerYieldValue>

quantizeSync

quantizeSync(pointContainer: PointContainer, palette: Palette): PointContainer

Inherited from AbstractImageQuantizer.quantizeSync
- Defined in image/imageQuantizer.ts:18
Parameters
- pointContainer: PointContainer
- palette: Palette
Returns PointContainer
