Functions ¶
func NewGray ¶
NewGray converts argument img to a new image of grayscale and returns it. Result differes depending on image format.
func SaveImage ¶
SaveImage saves image to file. Format is recognized from extension in path. Default is PNG.
func ToAvarage ¶
ToAvarage sets avarage values for each pixel in its area size*size, e.g. avarage value of {9, 5, 16} is 10.
func ToMedian ¶
ToMedian sets median values for each pixel in its area size*size, e.g median value in {9, 5, 17} is 9.
func ToMonochrome ¶
ToMonochrome convertes image to black and white. Higher threshold means darker image.
