Javacpp-presets: In OpenCV: How to let int[][] conert to Mat ？

We have to do it manually with loops:

We can always add helper methods for that though.

@saudet Hi，this code is correct?

int[][] kk = {{0,0,0,0},{0,0,0,0},{0,0,0,0}}
PointerPointer pointer = new PointerPointer(3);
for(int i = 0; i < 3; i++){
     pointer.put(kk[i]);
}
 Mat pano = new Mat(row, col, CV_32SC1, pointer);

[saudet]

No, try to use indexers instead.

But 'Mat(int rows, int cols, int type, Pointer data) ' must need Pointer, what can I do ?

[saudet]

No, it doesn't.

Try something like this:

Mat pano = new Mat(row, col, CV_32SC1);
IntIndexer idx = mat.createIndexer();
for (int i = 0; i < kk.length; i++) {
    idx.put(i, kk[i]);
}

Thanks! It is ok!
