Hi Guys,

CC Workstation currently supports rotation at 90 deg only. I want to rotate the image at random angles. Some debugging took me to BililearInterpolation.DLL.
My question is that do I need to update the BilinearInterpolation class or there is some other way of doing it?

Any pointers will be helpful.

Thanks,
Vaibhav

Hi, the BilinearInterpolation.dll actually renders the image, applying all it's transforms, LUTs etc, directly to the buffer that is ultimately rendered to the screen. As you've discovered, it does not support arbitrary rotations because that would greatly complicate things, and there would also be performance implications, as the amount of additional math that would have to be done is likely considerable. There are a couple of approaches you could take:

- Modify the interpolator to support arbitrary rotations
- Write your own interpolator (maybe use a toolkit that exploits GPUs :)
- Write a custom renderer plugin using OpenGL or WPF

Hope this helps,
Stewart
