如何在OpenCV 2.0中的IplImage变量类型中转换Mat变量类型? [英] How to convert a Mat variable type in an IplImage variable type in OpenCV 2.0?

问题描述

我正在尝试在OpenCV中旋转图像.

I am trying to rotate an image in OpenCV.

我使用了我在Stack Overflow上找到的这段代码:

I've used this code that I found here on Stack Overflow:

Mat source(img);
Point2f src_center(source.cols/2.0, source.rows/2.0);
Mat rot_mat = getRotationMatrix2D(src_center, 40.0, 1.0);
Mat dst;
warpAffine(source, dst, rot_mat, source.size());

一旦我填写了dst Mat变量类型，我想将其放回IplImage变量类型，关于如何执行此操作的任何想法?

Once I have my dst Mat variable type filled up I would like to put it back to an IplImage variable type, any idea about how to do this?

推荐答案

在新的OpenCV 2.0 C ++接口中，确实没有必要在Mat和IplImage之间来回切换，但是如果您愿意，可以使用IplImage运算符:

In the new OpenCV 2.0 C++ interface it's not really necessary to change from back and forth between Mat and IplImage, but if you want to you can use the IplImage operator:

IplImage dst_img = dst;

请注意，仅创建了IplImage标头，并且将共享数据(像素).有关更多信息，请参见 OpenCV C ++接口或image.cpp示例在OpenCV-2.0/samples/c目录中.

Note that only the IplImage header is created and the data (pixels) will be shared. For more info see the OpenCV C++ interface or the image.cpp example in the OpenCV-2.0/samples/c directory.
