type MedianCutQuantizer ¶

type MedianCutQuantizer struct {
	NumColor int
}

MedianCutQuantizer constructs a palette with a maximum of NumColor colors by iteratively splitting clusters of color points mapped on a three-dimensional (RGB) Euclidian space. Once the number of clusters is within the specified bounds, the resulting color is computed by averaging those within each grouping.
