Functions

func AddFilter

func AddFilter(img image.Image, outputFileName, outputDirName, filter string, filterLevel float64)

AddFilter adjusts different filters like brightness, contrast, saturation for the given image.

GreyOut will grey out the image as per the greyStrength and output to the outputFileName in the desired outputDirName folder

func GreyOutOld

func GreyOutOld(img image.Image, greyStrength uint8, outputFileName, outputDirName string)

GreyOutOld will grey out the image as per the greyStrength and output to the outputFileName in the desired outputDirName folder

func IsolateColor

func IsolateColor(img image.Image, inputColor color.RGBA, outputFileName, outputDirName string) error
