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disp_lut is obsolete and is only provided for reasons of backward compatibility.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 centre of the graphic. Scale allows scaling of the graphic, whereas 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.
Window handle.
Row of centre of the graphic.
Default value: 128
Typical range of values: 0 ≤ Row ≤ 511
Column of centre of the graphic.
Default value: 128
Typical range of values: 0 ≤ Column ≤ 511
Scaling of the graphic.
Default value: 1
List of values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Typical range of values: 0 ≤ Scale ≤ 20
set_lut(WindowHandle,'color1') disp_lut(WindowHandle,256,256,1) get_mbutton(WindowHandle,_,_,_) set_lut(WindowHandle,'sqrt') disp_lut(WindowHandle,128,128,2)
disp_lut returns 2 (H_MSG_TRUE) if the hardware supports a look-up-table, the window is valid and the parameters are correct. Otherwise an exception is raised.
