halcon-dev_set_line_width设置region，contour输出的线宽

在HDevelop中

dev_open_window(10,10,600,300,'black',WindowHandle)
dev_set_line_width (3)
*设置region，contour输出的线宽

*****坐标数组****
rows1:=[20,100,100,20,20]
cols1:=[20,20,250,250,20]
radius:=[20,20,20,20,20]
rows2:=[20,20,100,100,20]
cols2:=[320,550,550,320,320]
*注意：坐标数组的第一个值和最后一个值相同，用以形成一个封闭的多边形轮廓

gen_contour_polygon_rounded_xld (Contour, rows1, cols1, radius, 1)
*创建带圆角的多边形轮廓，坐标和圆角可以通过数组的形式指定
*参数1：输出轮廓
*参数2：多边形的行坐标
*参数3：多边形的列坐标
*参数4：圆角的半径
*参数5：样本的距离

gen_contour_polygon_xld (Contour1, rows2, cols2)
*不带圆角的多边形轮廓

dev_display (Contour)
dev_display (Contour1)
