[Rtk-users] DRR image generation from 3D CT

[Isuru Suranga Wijesinghe]

The problem is in the RTK I think. I was able to successfully save the
output image as the .png extension with an ITK eample.
I just checked  with CMake GUI and it doesn't contain a such module.
Please see the attachment. Any alternative approach is there ?
