There are several resizing alogirthms present in FPC. see the extinterpolation
unit.
how it happens is: create a canvas, and draw the image on the canvas with the
correct
interpolation.
If you want to create a new image in memory, create an TFPImageCanvas with the
desired
size, and draw the original canvas with the correct interpolation routine.
