Functions ¶
func AddGray ¶
AddGray accepts two grayscale images and adds their pixel values. If the result for a given position overflows uint8, the result will be clamped to max uint8 (255). Example of usage:
res, err := blend.AddGray(gray1, gray2)
func AddGrayWeighted ¶
func AddGrayWeighted(img1 *image.Gray, w1 float64, img2 *image.Gray, w2 float64) (*image.Gray, error)
AddGrayWeighted accepts two grayscale images and adds their pixel values using the following equation: res(x, y) = img1(x, y) * w1 + img2(x, y) * w2 If the result for a given position overflows uint8, the result will be clamped to max uint8 (255). If the result for a given position is negative, then it will be clamped to 0. Example of usage:
res, err := blend.AddGrayWeighted(gray1, 0.25, gray2, 0.75)
func AddScalarToGray ¶
AddScalarToGray takes a grayscale image and adds an integer value to all pixels of the image. If the result overflows uint8, the result will be clamped to max uint8 (255). Example of usage:
res := blend.AddScalarToGray(img, 56)
