Interpolation algorithms

Interpolation algorithms let you fine-tune how images are resampled. Each algorithm balances image quality against performance: in general, the higher the image quality, the slower the performance. Quality and peformance differ based on image type and the size of the source file. The following table describes the algorithms and their named equivalents based on average test results:

Highest image quality with low performance : lanczos
	
Good image quality with slightly higher performance: mitchell, quadratic

Medium quality image with medium performance : hamming, hanning, hermite
	
Slightly distored image quality with high performance : blackman, bessel
	
Poor image quality with highest performance : nearest, bicubic, bilinear
