Hi,
It looks like you have done everything right. Just click on the white Play button at the bottom left corner and the image will appear at the output.

Happy experimenting

Hi Lukas,

Assuming that you have already allocated space for your kuvio_image, you can copy it across using OpenCv functions. Possible functions for this are for example cv::cvtColor, cv::mixChannels and cv::merge. Please read OpenCv documentation on how they are used.

For example, if your opencv image is a 24-bit RGB image, the copying can be done simply as follows:

int my_opencv_function(/*params,*/  kuvio_image* imgOut)
{
  if (imgOut->type == kuvio_rgb32_image_type)
    {
      cv::Mat myOpenCvImage = ... // Get or create an RGB image. eg. cv::imread
      /// ...do stuff with the image and copy to kuvio_image
      cv::mixChannels(myOpenCvImage, OpenCvMat(imgOut, OpenCvMat::Rgb24), {0, 0, 1, 1, 2, 2});
}

Please bear in mind that the sizes of the allocated kuvio_image and the size of the image in cv::Mat myOpenCvImage must be identical.
