disp_regionT_disp_regionDispRegionDispRegion (Operator)

Name

disp_regionT_disp_regionDispRegionDispRegion — Displays regions in a window.

Signature

Description

disp_regiondisp_regionDispRegionDispRegionDispRegion displays the regions in DispRegionsDispRegionsDispRegionsDispRegionsdispRegions in the output window. The parameters for output can be set with the operators set_colorset_colorSetColorSetColorSetColor, set_grayset_graySetGraySetGraySetGray, set_drawset_drawSetDrawSetDrawSetDraw, set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidth, etc.

The color(s) for the display of the regions are determined with set_colorset_colorSetColorSetColorSetColor, set_rgbset_rgbSetRgbSetRgbSetRgb, set_grayset_graySetGraySetGraySetGray or set_coloredset_coloredSetColoredSetColoredSetColored. If more than one region is displayed and more than one color is set, the colors are assigned in a cyclic way to the regions.

The form of the region for output can be modified by set_paintset_paintSetPaintSetPaintSetPaint (e.g. encompassing circle, convex hull). The command set_drawset_drawSetDrawSetDrawSetDraw determines if the region is filled or only the boundary is drawn. If only the boundary is drawn, the thickness of the boundary will be determined by set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidth and the style by set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyle.

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

Example (HDevelop)

* Output with 12 colors:
set_colored(WindowHandle,12)
disp_region(SomeSegments,WindowHandle)

* Symbolic representation:
set_draw(WindowHandle,'margin')
set_color(WindowHandle,'red')
set_shape(WindowHandle,'ellipse')
disp_region(SomeSegments,WindowHandle)

* Representation of a margin with pattern:
set_draw(WindowHandle,'margin')
set_color(WindowHandle,'blue')
set_line_style(WindowHandle,[12,3])
disp_region(Segments,WindowHandle)

Result

disp_regiondisp_regionDispRegionDispRegionDispRegion returns 2 (H_MSG_TRUE).
