set_line_widthT_set_line_widthSetLineWidthSetLineWidthset_line_width (算子名称)

名称

set_line_widthT_set_line_widthSetLineWidthSetLineWidthset_line_width — Define the line width for region contour output.

参数签名

描述

set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width defines the line width (in pixel) in which a region contour is displayed (e.g., with disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region, disp_linedisp_lineDispLineDispLineDispLinedisp_line, disp_polygondisp_polygonDispPolygonDispPolygonDispPolygondisp_polygon, etc.) 该算子 get_line_widthget_line_widthGetLineWidthGetLineWidthGetLineWidthget_line_width returns the current value for the window. Some output devices may not allow to change the contour width. If it is possible for the current device, it can be queried with query_line_widthquery_line_widthQueryLineWidthQueryLineWidthQueryLineWidthquery_line_width.

注意

The line width is important if the output mode was set to 'margin' (see set_drawset_drawSetDrawSetDrawSetDrawset_draw). If the line width is greater than one, regions may not always be displayed correctly.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

结果

set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width returns 2 ( H_MSG_TRUE) if the parameter is correct and the window is valid. Otherwise an exception is raised.
