I'm researching about error finding on 2D image (Grajscale for now), and couldn't find anything about read pixel colour (not RGB only greyscale)
Now I have started reading little more on at Khronos Group’s website and is possible to get only one number per pixel (for greyscale only 0-255)?
Like on picture attached, every pixel have int or float number to represent pixel colour
In specification exist Cl_R or CL_INTENSITY may do single floats or int at each index, maybe I'm wrong.....
Much easier would be to work only with one colour insted od RGB(3 colour)
