Functions

func CountBrighterPixels

func CountBrighterPixels(baseImage, countImage image.Image) (int, error)

CountBrighterPixels takes two same size image, return how many pixels in countImage brighter than baseImage.

func CountDiffPixels

func CountDiffPixels(imageA, imageB image.Image, threshold uint8) (int, error)

CountDiffPixels takes two images of the same size, and returns how many pixels are different.

func CountPixels

func CountPixels(image image.Image, clr color.Color) int

CountPixels returns how many pixels in the specified color are contained in image.

func CountPixelsWithDiff

func CountPixelsWithDiff(image image.Image, clr color.Color, colorMaxDiff uint8) int

CountPixelsWithDiff returns how many pixels in the specified color are contained in image with max diff.

func DumpImageToPNG

func DumpImageToPNG(ctx context.Context, image *image.Image, path string) error

DumpImageToPNG saves the image to path.
