Thanks for the pointers. I can't find the extinterpolation unit though.
I think I am getting an idea of how to do what I want. The only thing that
eludes me is how to get the FPImage into the TImage control? The class
hierarchy seems rather confusing there. :-(
Thanks
Charl
PS Please excuse my ignorance, this is the first time I am working with
images!

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.
