描述
disp_crossdisp_crossDispCrossDispCrossDispCrossdisp_cross displays one or several crosses in the output
window. A cross is described by the coordinates of the center point
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn), the length of its bars SizeSizeSizeSizesizesize and the
orientation AngleAngleAngleAngleangleangle.
The operators used to control the display of regions
(e.g., set_colorset_colorSetColorSetColorSetColorset_color, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw,
set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_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_colorSetColorSetColorSetColorset_color。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
