Interpolation Methods for Image Scaling

[Kazanian2]

Hi,
we are considering using GPUImage3 for some image processing tasks in our project. Unfortunately, I couldn't figure out which interpolation methods are available for image resizing. I read that Lanczos Resampling was used in GPUImage2, but I couldn't find information for GPUImage3.
Can anybody give me information on that?

Thanks in advance!
