OpenCV调整大小更改值

Question

maybe this is very simple, but somehow I can't figure out what's wrong. I have a single columns cv::Mat which I wish to resize to a square matrix. This is the code:

int matSize = 5;
Mat src(matSize, 1, CV_8UC1);
//Fill src with data...(all ones but one zero)
cout << "src:\n" << src << endl;

Mat output(matSize, matSize, CV_8UC1);
resize(src.t(), output, output.size());
cout << "output:\n"output << endl;

The output looks like this:

src:
[1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
output:
[1, 1, 1, 1, 1;
1, 1, 1, 1, 1;
1, 1, 1, 1, 1;
1, 1, 1, 1, 1;
1, 1, 1, 1, 1]

So the zero gets lost! I need this in a bigger context, but wish to get it to work in a small scale first. Please help!

我自己解决了这个问题，正确的函数是“重塑”而不是“缩放”，后者用于“缩放”矩阵，而不是更改其标头以获取对数据的不同访问。
