limits of the warping algorithmus? (digital image processing)

Hi Mathematicians,

are there any limitations as far as the size of an image is concerned to
be used with the warp-algorithmus [ImageWarp] as implemented in the
digital imaging add-on?

There is no problem using it for small images, but for bigger ones (i.e.
1028 x 808) error messages like

CompiledFunction::cfn : Numerical error encountered at instruction 34;
proceeding with uncompiled evaluation

which leads finally to:

General::stop : Further output of CompiledFunction::cfn will be
suppreessed...



And my second question:

Because I don't have any ideas on the warping algorithm used: For more
complicated warpings is it necessary using some special sequences of the
points concerned?


Thanks a lot for each hint

Harald
