When upscaling it's similar to NearestNeighbor. -- `Linear` - Bilinear filter, smooth and reasonably fast. -- `MitchellNetravali` - А smooth bicubic filter. -- `CatmullRom` - A sharp bicubic filter. -- `Gaussian` - Blurring filter that uses gaussian function, useful for noise removal. -- `Lanczos` - High-quality resampling filter for photographic images yielding sharp results, slower than cubic filters. +- `NearestNeighbor` - Fastest resampling filter, no antialiasing. The full list of supported filters: NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine.
