少有人走的路见下面的halcon代码，第4句将无法在屏幕上绘制，因为列坐标529。
gen_circle(Circle, 344.02661132813, 444.00024414063, 2) gen_circle(Circle, 343.42919921875, 472.00024414063, 2) gen_circle(Circle, 342.57739257813, 501.00024414063, 2) gen_circle(Circle, 341.91528320313, 529.00024414063, 2)
在绘图前，即使你加上下面这句也没用。
dev_open_window(0, 0, 2000, 2000, 'black', WindowHandle)
超出501的部分仍然画不出来。
解决办法是载入一张大于你的最大行列坐标的图片，然后再画就可以了。
测试代码，各位可以试下：
* Code generated by Image Acquisition 01
read_image (Image, 'C:/Users/Administrator/Desktop/liu/liu/123.bmp')
*dev_open_window(0, 0, 2000, 2000, 'black', WindowHandle)
dev_set_color('green')
