Description

disp_lutdisp_lutDispLutDispLutdisp_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_lutDispLutDispLutdisp_lut creates a graphical view of the table assigned to the output window with the logical window number WindowHandleWindowHandleWindowHandlewindowHandlewindow_handle and displays it for every basic color (red, green, blue). RowRowRowrowrow and ColumnColumnColumncolumncolumn define the position of the center of the graphic. ScaleScaleScalescalescale 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_colorSetColorSetColorset_color, set_rgbset_rgbSetRgbSetRgbset_rgb, etc.). Tables for displaying “false colors” are viewed with red, green and blue for each color component.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

WindowHandleWindowHandleWindowHandlewindowHandlewindow_handle (input_control)  window → HWindow, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Window handle.

RowRowRowrowrow (input_control)  point.y → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Row of center of the graphic.

Default: 128

Value range: 0 ≤ Row Row Row row row ≤ 511

ColumnColumnColumncolumncolumn (input_control)  point.x → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Column of center of the graphic.

Default: 128

Value range: 0 ≤ Column Column Column column column ≤ 511

ScaleScaleScalescalescale (input_control)  integer → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Scaling of the graphic.

Default: 1

Result

disp_lutdisp_lutDispLutDispLutdisp_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.
