Convert cv::Mat to Magick::Image

Question

I am attempting to convert an OpenCV C++ cv::Mat to an ImageMagick Magick::Image. The only examples I can find use the older, C OpenCV iplImage (see, for example, here).

Is there a simple way of achieving this?

Answer 1

It's as simple as this:

Image Mat2Magick(Mat& src)
{
   Image mgk(src.cols, src.rows, "BGR", CharPixel, (char *)src.data);
   return mgk;
}

Note that the function does not copy the data. If the magik image is released before you use the Mat image, result is SEGFAULT

Answer 2

mat is always bigger then the image itself. The width is changed to multiple of 2 for sake of more efficient accessing the image data.
