Dear RadiAnt,
Just be reading a few threads in the forum, it is clear that you have a program that people use because they like it. It is also nice to see how fast you reply to peoples comments, that is a great quality - along with the program itself. I'm a fan!
- If I try to make a movie from the 'snapshot' function in 3D it fails in 4K UHD. All the frames gets rendered and the file appear in the sub-directory, but it's a 0 KB file. I don't have the need for such high res., but I tried it anyway as it is a very cool feature. I use Win7 (64), GTX970. Just want to mention.
- Also a small feature: Would it be possible to get a feature to adjust/turn off the interpolation? E.g. off, nearest neighbour, linear, bi-linear etc.? At least on/off? Being able to turn off interpolation and knowing the type of used interpolation is great for evaluation image quality from the modality.
Best regards
Henrik B.

Dear Henrik,
Thank you for your kind words! Sometimes it can take a bit longer to get a reply here but we do what we can with our limited resources :-)
Anyway, thanks for pointing out that 4K does not work on Windows 7. It actually only works on Windows 10 (we use the MP4 codec provided by the system). A fresh RadiAnt RC build is available with the 4K option removed for anything older than Windows 10.
The interpolation used in RadiAnt is bi-linear. When you press Ctrl + 1 then interpolation is effectively disabled, as 1 DICOM pixel corresponds exactly to 1 screen pixel. In future versions we may add additional interpolation modes, however, no time-frame can be given.
Greetings,
Maciej
