Halcon學習之八：圖像區域疊加與繪制

overpaint_gray ( ImageDestination, ImageSource : : : )

將灰度值不相同區域用不同顏色繪制到ImageDestination中，ImageSource包含希望的灰度值圖像

overpaint_region ( Image, Region : : Grayval, Type : )

將Region以一個恆定的灰度值繪制到Image圖像中

paint_gray ( ImageSource, ImageDestination : MixedImage : : )

將ImageSource的圖像繪制到ImageDestination中，形成MixedImage。

paint_region ( Region, Image : ImageResult : Grayval, Type : )

將Region以一個恆定的灰度值繪制到Image圖像中

paint_xld ( XLD, Image : ImageResult : Grayval : )

將XLD以一個恆定的灰度值繪制到Image圖像中

set_grayval ( Image : : Row, Column, Grayval : )

設置Image圖像中坐標為（Row，Column）的灰度值

15* /* Paint colored xld objects into a gray image */

16* /* read and copy image to generate a three channel image */

17copy_image (Image2, image0)

18copy_image (Image2, image1)

19compose3 (image0, Image2, image1, MultiChannelImage)

20* /* extract subpixel border */

21threshold_sub_pix (MultiChannelImage, Border, 128)

22* /* select the circle and the arrows */

23circle := Border[14]

24arrow := Border[16]

25ObjectsConcat := [circle,arrow]

26* /* paint a green circle and white arrows (to paint all

27* * objects e.g. blue, pass [0,0,255] tuple for GrayVal) */
