描述

dev_set_line_widthdev_set_line_widthDevSetLineWidthDevSetLineWidthDevSetLineWidthdev_set_line_width defines the line width (in pixel) that is used to display region contours (in 'margin'"margin""margin""margin""margin""margin" mode), XLDs, and other geometric output (e.g., disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region, disp_linedisp_lineDispLineDispLineDispLinedisp_line, etc.).

For more information see the description of the operator set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width。However, in contrast to that operator the new line width is also used for all new graphics windows that are opened afterwards.

注意

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.

参数

示例（HDevelop）

read_image(Image,'monkey')
threshold(Image,Region,128,255)
dev_set_draw('margin')
dev_set_line_width(5)
dev_clear_window ()
dev_display(Region)

结果

If the values of the specified parameters are correct, dev_set_line_widthdev_set_line_widthDevSetLineWidthDevSetLineWidthDevSetLineWidthdev_set_line_width 返回 2 ( H_MSG_TRUE )。否则，将抛出一个异常并返回错误代码。
