描述

set_insertset_insertSetInsertSetInsertSetInsertset_insert defines the function, with which pixels are displayed in the output window. It is e.g., possible for a pixel to overwrite the old value. In most of the cases there is a functional relationship between old and new values.

The definition value is only valid for the valid window. Output operators that honor ModeModeModeModemodemode are e.g., disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region, disp_polygondisp_polygonDispPolygonDispPolygonDispPolygondisp_polygon,disp_circledisp_circleDispCircleDispCircleDispCircledisp_circle。

Possible display functions are:

'copy'：

'complement'：

There may not be all functions available, depending on the physical display. However, “copy” is always available.
