Description

disp_lutdisp_lutDispLutdisp_lutDispLutDispLut 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_lutDispLutdisp_lutDispLutDispLut creates a graphical view of the table assigned to the output window with the logical window number WindowHandleWindowHandleWindowHandleWindowHandleWindowHandlewindowHandle and displays it for every basic color (red, green, blue). RowRowRowRowRowrow and ColumnColumnColumnColumnColumncolumn define the position of the centre of the graphic. ScaleScaleScaleScaleScalescale 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_colorset_colorSetColorset_colorSetColorSetColor, set_rgbset_rgbSetRgbset_rgbSetRgbSetRgb, etc.). Tables for displaying “false colors” are viewed with red, green and blue for each color component.

Example (HDevelop)

set_lut(WindowHandle,'color1')
disp_lut(WindowHandle,256,256,1)
get_mbutton(WindowHandle,_,_,_)
set_lut(WindowHandle,'sqrt')
disp_lut(WindowHandle,128,128,2)

Example (C)

set_lut(WindowHandle,"color1") ;
disp_lut(WindowHandle,256,256,1) ;
get_mbutton(WindowHandle,NULL,NULL,NULL) ;
set_lut(WindowHandle,"sqrt") ;
disp_lut(WindowHandle,128,128,2) ;

Example (HDevelop)

set_lut(WindowHandle,'color1')
disp_lut(WindowHandle,256,256,1)
get_mbutton(WindowHandle,_,_,_)
set_lut(WindowHandle,'sqrt')
disp_lut(WindowHandle,128,128,2)

Example (HDevelop)

set_lut(WindowHandle,'color1')
disp_lut(WindowHandle,256,256,1)
get_mbutton(WindowHandle,_,_,_)
set_lut(WindowHandle,'sqrt')
disp_lut(WindowHandle,128,128,2)

Example (HDevelop)

set_lut(WindowHandle,'color1')
disp_lut(WindowHandle,256,256,1)
get_mbutton(WindowHandle,_,_,_)
set_lut(WindowHandle,'sqrt')
disp_lut(WindowHandle,128,128,2)

Example (HDevelop)

set_lut(WindowHandle,'color1')
disp_lut(WindowHandle,256,256,1)
get_mbutton(WindowHandle,_,_,_)
set_lut(WindowHandle,'sqrt')
disp_lut(WindowHandle,128,128,2)

Result

disp_lutdisp_lutDispLutdisp_lutDispLutDispLut 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.
