halconpaint_region绘制区域到图像内

在HDevelop中

ma.jpg

dev_update_off()
read_image(Image,'D:/bb/tu/ma.jpg')
get_image_size (Image, Width, Height)
area_center (Image, Area, Row, Column)
gen_circle (Circle, Row, Column, 50)

paint_region (Circle, Image, ImageResult,[255,255,255], 'fill')
*函数作用：绘制region到image内
*参数1：绘入图像内的区域
*参数2：包含绘入区域的图像
*参数3：结果图像
*参数4：期望的区域灰度值--填充区域的颜色值
*参数5：所绘区域类型，如填充或边界    'fill', 'margin'
