set_pixel — Define a color lookup table index.
set_pixel is obsolete and is only provided for
reasons of backward compatibility.
set_pixel( : : WindowHandle, Pixel : )
set_pixel sets pixel values: colors
(set_color, set_rgb, etc.) and gray values
(set_gray) are coded together into a number, called
pixel. This 'pixel' is an index in the color lookup table. It ranges
from 0 to 1 in b/w images and 0 to 255 color images with 8 bit
planes. It is different from the 'pixel' ("picture element") in
image processing. Therefore HALCON distinguishes between pixel and
image element (or gray value).
The current value can be queried with get_pixel.

set_pixel returns 2 (
H_MSG_TRUE)
if the parameter is correct and
the window is valid. Otherwise an exception is raised.
