OpenCV Save CvRect to File 保存CvRect变量到文件

 

在OpenCv中，我们有时候需要查看CvRect变量的值，我们可以通过将其保存到文件来查看，保存的代码如下：

 

// Save CvRect rect to 'rect.yml'

CvFileStorage *fs = cvOpenFileStorage("rect.yml", 0, CV_STORAGE_WRITE);

if (!fs) {

    fprintf(stderr, "Could not open file ..\n");

    return;

}

cvStartWriteStruct(fs, "rect", CV_NODE_SEQ | CV_NODE_FLOW);

cvWriteInt(fs, 0, rect.x); cvWriteInt(fs, 0, rect.y); cvWriteInt(fs, 0, rect.width); cvWriteInt(fs, 0, rect.height);

cvEndWriteStruct(fs);

cvReleaseFileStorage(&fs);
