[Insight-users] Re sample Filter without deleting existing pixels

[slorentz]

Hello,

thanks for the quick answer.

However: the reason I would like to use the ResampleFilter is that the
geometric transform is already applied. The background is: I have two
images, compute the translational transform ("registration"), and then I
need to stitch these images together. So when I use the PasteImageFilter
then I need to apply the transform myself... All I would need would be the
ResampleFilter without overwriting existing pixels...

Any other hints, especially on image stitching?

Regards,
Sabine Lorentz
