disp_crossT_disp_crossDispCrossDispCrossdisp_cross (Operator)

disp_crossT_disp_crossDispCrossDispCrossdisp_cross — Displays crosses in a window.

Signature

Description

disp_crossdisp_crossDispCrossDispCrossdisp_cross displays one or several crosses in the output window. A cross is described by the coordinates of the center point (RowRowRowrowrow,ColumnColumnColumncolumncolumn), the length of its bars SizeSizeSizesizesize and the orientation AngleAngleAngleangleangle. The operators used to control the display of regions (e.g., set_colorset_colorSetColorSetColorset_color, set_grayset_graySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawset_draw, set_line_widthset_line_widthSetLineWidthSetLineWidthset_line_width) can also be used with crosses. Several crosses can be displayed with one call by using tuple parameters. For the use of colors with several crosses, see set_colorset_colorSetColorSetColorset_color.

Execution Information

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