disp_lut — Graphical view of the look-up-table (lut).
disp_lut is obsolete and is only provided for
reasons of backward compatibility.
disp_lut( : : WindowHandle, Row, Column, Scale : )
disp_lut displays a graphical view of the look-up-table (lut)
in the valid window. A look-up-table defines the transformation of
image gray values to colors/gray levels on the screen. On most systems
this can be modified.
disp_lut creates a graphical view of the table assigned to
the output window with the logical window number WindowHandle and
displays it for every basic color
(red, green, blue).
Row and Column define the position of the center of
the graphic.
Scale allows scaling of the graphic, whereby 1 means
displaying all 256 values, 2 means displaying 128 values, 3
means displaying only 64 values, etc.
Tables for monochrome-representations are displayed in the currently set
color (see set_color, set_rgb, etc.).
Tables for displaying “false colors” are viewed with red, green and blue
for each color component.

the window is valid and the parameters are correct.
Otherwise an exception is raised.
