Input

HxImageRep img

The input image

HxValue val

The input value

Return value

HxImageRep

The substraction of the input image and the input value.

Description

The function HxSubVal substracts the HxValue val from every pixel value in the input image and stores the result in the corresponding pixel of the output image.
