What it does

Resamples, i.e. changes the resolution of the selected image(s).

How to proceed

  1. Select the preferred resampling or interpolation method:
    • Average Resampling: computes the average pixel color of the pixels in the sample area, and replaces the entire area with this average.
    • Bicubic resampling: calculates the values of the new dots on the basis of a weighted average of the pixels in the same area.
    • Bicubic B-Spline resampling: is a modified bicubic interpolation with more sharpening effects and is recommended for upsampling.
    • Bilinear resampling: uses weighted interpolation between 4 pixels in the original image.
    Note: Bicubic gives the best result for photographs (but takes the longest to compute).
  2. Enter the preferred resolution, for example 72 ppi for screen viewing.
  3. To only resample images with a resolution below a particular threshold, select the Resample above ... ppi checkbox and enter a value.

    For example, if you enter 150 ppi, only images with a resolution above 150 ppi will be resampled.
