C++ IplImage*的若干bug之一：cvCreateImage问题

源代码：

IplImage* image_src, TempImg;  //定义两个IplImage*变量
IplImage *image = cvLoadImage(“test.jpg”);  //加载一幅图片
int width  = image->width;
int height = image->height;

image_src = cvCloneImage(image);	
cvSetImageROI(image_src, cvRect( 0, 0, width, height));
TempImg = cvCreateImage(cvSize(width, height), image->depth, image->nChannels);
cvCopy(image_src, TempImg);

在编译的过程中，出现以下错误：

错误： ‘operator=’在‘TempImg = cvCreateImage(cvSize(width, height), image->_IplImage::depth, image->_IplImage::nChannels)’中没有匹配
附注： 备选是：
In file included from /usr/local/include/opencv2/core/core_c.h:47:0,
                 from /usr/local/include/opencv/highgui.h:45,
                 from ../src/API_annotaDeal/API_annotaDeal.cpp:22:

错误： 不能将‘void cvCopy(const CvArr*, CvArr*, const CvArr*)’的实参‘2’从‘IplImage {aka _IplImage}’转换到‘CvArr* {aka void*}’

修改后代码：

IplImage* image_src;  //定义IplImage*变量
IplImage *image = cvLoadImage(“test.jpg”);  //加载一幅图片
int width  = image->width;
int height = image->height;

image_src = cvCloneImage(image);	
cvSetImageROI(image_src, cvRect( 0, 0, width, height));
IplImage* TempImg = cvCreateImage(cvSize(width, height), image->depth, image->nChannels);
cvCopy(image_src, TempImg);

编译通过。
