Description

dev_set_drawdev_set_drawDevSetDrawDevSetDrawDevSetDrawdev_set_draw defines the fill mode for regions. If DrawModeDrawModeDrawModeDrawModedrawModedraw_mode is set to 'fill'"fill""fill""fill""fill""fill", regions are displayed filled, if set to 'margin'"margin""margin""margin""margin""margin", only contours are displayed. In the 'margin'"margin""margin""margin""margin""margin" mode, the appearance of the contours can be affected by dev_set_line_widthdev_set_line_widthDevSetLineWidthDevSetLineWidthDevSetLineWidthdev_set_line_width and set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyleset_line_style.

For more information see the description of the operator set_drawset_drawSetDrawSetDrawSetDrawset_draw. However, in contrast to that operator the draw mode is also used for all new graphics windows that are opened afterwards.

Attention

Using the code export feature of HDevelop, the code that is generated for this operator may have a different behavior than the related HALCON operator. For a detailed description of the code export of HDevelop graphics operators into the different programming languages see in the “HDevelop User's Guide” the chapter Code Export -> General Aspects of Code Generation -> Graphics Windows.
