func PixelsUnweighted 

func PixelsUnweighted(img image.Image) []color.Color

PixelsUnweighted returns all pixel colors from the image in row-major order. Kept for internal use where a flat []color.Color slice is needed.

Types

type WeightedPixel 

type WeightedPixel struct {
	Color  color.Color
	Weight float32
}

WeightedPixel is a color sample with a weight in [0.0, 1.0]. Weight reflects alpha: fully opaque = 1.0, fully transparent = 0.0.

func Pixels 

func Pixels(img image.Image) []WeightedPixel

Pixels returns all non-transparent pixels from the image as WeightedPixels. Fully transparent pixels (alpha == 0) are skipped. Semi-transparent pixels are included with weight = alpha / 65535. Fully opaque pixels have weight 1.0.
