The following downsampling methods are available:
-
Resampling:
replaces the entire area with the pixel color of the pixel at the
center of the sample area.
-
Average downsampling:
computes the average pixel color of the pixels in the sample area,
and replaces the entire area with this average.
-
Bicubic downsampling:
the value of the new dots is calculated on the basis of a weighted
average of the pixels in the sample area. This method offers the
best results with smooth tonal gradations, but takes the longest to
compute.
