Halcon 学习之八:图像区域叠加与绘制
overpaint_gray ( ImageDestination, ImageSource : : : )
将灰度值不相同区域用不同颜色绘制到 ImageDestination 中, ImageSource 包含希望
的灰度值图像
overpaint_region ( Image, Region : : Grayval, Type : )
将 Region 以一个恒定的灰度值绘制到 Image 图像中
paint_gray ( ImageSource, ImageDestination : MixedImage : : )
将 ImageSource 的图像绘制到 ImageDestination 中,形成 MixedImage。
paint_region ( Region, Image : ImageResult : Grayval, Type : )
将 Region 以一个恒定的灰度值绘制到 Image 图像中
paint_xld ( XLD, Image : ImageResult : Grayval : )
将 XLD 以一个恒定的灰度值绘制到 Image 图像中
set_grayval ( Image : : Row, Column, Grayval : )
设置 Image 图像中坐标为(Row,Column)的灰度值
