halcon与C#混合编程（二）读取并处理图片
转载：http://www.cnblogs.com/hanzhaoxin/archive/2013/02/03/2890871.html
示例：读取并处理图片
halcon源码：
1: *读取图片
2: read_image(Image,'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）：
1: //
2: // File generated by HDevelop for HALCON/DOTNET (C#) Version 10.0
3: //
4: // This file is intended to be used with the HDevelopTemplate or
5: // HDevelopTemplateWPF projects located under %HALCONEXAMPLES%\c#

30:
31: //读取图片
32: //dev_close_window(...);
33: ho_Image.Dispose();
