既然提到vs2010了，那么我说一下gdi+的做法。
1、从文件创建一个Image对象（Image::FromFile
2、根据要保存的部分的大小（分辨率）创建一个Bitmap对象（直埋轿接用它构造函数即可
2、从Bitmap对象创建一个Graphics对象（Graphics::FromImage
3、调用Graphics对象上的DrawImage方法，
g->DrawImage(步骤1的Image对象指针, 0, 0, x, y, w, h, UnitPixel)
其中x、y是要截取的部分的左上角的坐标，w和h是要截取的部分的大小（也就是目标图像的分辨率，步骤2中创建的图像的分辨率
4、调用Graphics对象上的Flush方法确保数据都写入Bitmap对象了
5、调用步骤2创建的Bitmap对象上的Save方法保存文件，这个具体你可以上网搜，关于那些clsid啥的应该竖亏送什么参数
类似抠图把，给图像加上mask，完后把纯旁mask保存下来，仅供参考

你好：的原因有很多，一般有以下几个方面：1. 程序设计不当：程序设计不合理，存在程序功能设计上的缺陷，导致在一些特定情况下出现意外退出的情况。
2. 编程问题：由于程序编卖笑写的不当，存在语法错误或逻辑错误袭纳，导致在使用过程中出现意外退出的情况。
3. 软件问题：由于软件本身存在漏洞，或者软件不兼容系统和硬件，也会导致程序意外退出的情况。
4. 硬件原因：由于系统中硬件资源不足，系统出现崩溃，也会导致程序意外退出的情况。谢谢提拍配没问
