Resampling methods

These interpolation methods are described in Cubic (sometimes called Bicubic): The color of each pixel is computed as the average color of the eight closest pixels in the original image. This usually gives the best result, but it naturally takes more time..

Wave type

Choose how the wave should look like:

  • Sawtooth

  • Triangle

  • Sinus
