resize-filter parameter enables control over the resizing filter used to generate a new image with a higher or lower number of pixels.
|Uses the value of nearby translated pixel values.|
|Uses an average of a 2x2 environment of a pixels.|
|Uses an average of a 4x4 environment of pixels, weighing the innermost pixels higher.|
|Uses the Lanczos filter to increase the ability to detect edges and linear features within an image and uses sinc resampling to provide the best possible reconstruction.|
|Lanczos3 uses a better approximation of the sinc resampling function. (Default)|
- When making an image smaller, use
bicubic, which has a natural sharpening effect.
- When making an image larger, use
bilinear, which has a natural smoothing effect.
- When resizing pixel art, use
nearest, which has a natural pixelation effect.
- When quality is the main concern, use
lanczos, which typically renders the best results.
