DESCRIPTION

The mlib_ImageInvert_Inp() function performs the in-place inversion of an image such that white becomes black, light gray becomes dark gray, and so on.

It uses the following equation:

srcdst[x][y][i] = (Gwhite + Gblack) - srcdst[x][y][i]

The values of Gwhite and Gblack for different types of images are:
