disp_lutdisp_lutDispLutDispLutDispLutdisp_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_lutdisp_lutDispLutDispLutDispLutdisp_lut creates a graphical view of the table assigned to the output window with the logical window number WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle and displays it for every basic color (red, green, blue). RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn define the position of the center of the graphic. ScaleScaleScaleScalescalescale 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_colorset_colorSetColorSetColorSetColorset_color, set_rgbset_rgbSetRgbSetRgbSetRgbset_rgb, etc.). Tables for displaying “false colors” are viewed with red, green and blue for each color component.
