func PxRGBAfunc ¶

func PxRGBAfunc(img image.Image) func(x, y int) (r, g, b, a uint32)

PxRGBAfunc returns function to get RGBA color values at (x, y) coordinates of image img. Returned function works the same as img.At(x, y).RGBA() but implements special cases for certain image types to use type-specific methods bypassing color.Color interface which escapes to the heap.

func SortFunc ¶

func SortFunc[S ~[]E, E any](x S, cmp func(a, b E) int)
