HalconDotNet.HOperatorException:“HALCON error #1301: Wrong value of control parameter 1 in operator write_image”

 

正确：

HOperatorSet.ReadImage(out ho_Image, "D://halcon_project//test3.bmp");
HOperatorSet.WriteImage(ho_Image, "bmp", 0, "D://test3a.bmp");

 

错误：

HOperatorSet.ReadImage(out ho_Image, "D://halcon_project//test3.bmp");
HOperatorSet.WriteImage(ho_Image, ".bmp", 0, "D://test3a.bmp");  //图片格式有个小点

HOperatorSet.WriteImage(ho_Image, ".bmp", 0, "test3a.bmp"); //保存需指定路径
