Functions ¶
func ChangeValue ¶ added in v0.1.3
ChangeValue will convert the color to HSV() space, and return a color with V set to value
func ColorDiff ¶
ColorDiff uses the euclidiean distance in the CIEL*a*b* colorsace to measure color difference.
func DetectMaxLum ¶
DetectMaxLum returns the largest pixel Luminance found in the image.
func DetectMinLum ¶
DetectMinLum returns the smallest pixel Luminance found in the image.
func Diff ¶
Diff uses the average euclidiean distance in the CIEL*a*b* colorsace to measure image difference.
func ForEachPixel ¶
ForEachPixel performs pixelFunc on every pixel in the image, going left to right, top to bottom.
func GetForegroundAndBackground ¶
GetForegroundAndBackground guesses the foreground and background color.
func LevelImage ¶
LevelImage linearly scales the luminance of pixels in an image, such that pixels which had luminance min are now black, and pixels which had luminance max are now white.
