halcon与C#混合编程（二）读取并处理图片

示例：读取并处理图片

halcon源码：

   1: *读取图片

'D:/MyFile/C#/HalconCsExample/示例图片.jpg')

   3: get_image_size(Image,Width,Height)

   4:  

   5: *图像处理

   6: rgb1_to_gray(Image,GrayImage)

导出的代码（ImagePro）：

//  This file is intended to be used with the HDevelopTemplate or

//  HDevelopTemplateWPF projects located under %HALCONEXAMPLES%\c#
