hi

I'm using the function in dificldades cvDistTransform with OpenCV in C #.
My code is as follows:
Cvlib.CvDistTransform (pimg ref, ref timg, (int) Cvlib.CV_DIST_L2, 3, NULL, NULL);
and has an error when I pass the parameters null.
does anyone know how to solve?

thank you

You can pass NULL for the kernel but not for the pointer. It should be like this:

Cvlib.CvDistTransform (pimg ref, ref timg, (int) Cvlib.CV_DIST_L2, 3, NULL, IntPtr.Zero)

I had this same problem and using IntPtr.Zero worked well for me.
