Is it possible to stretch/scale only the center part of an overlay image?
I don't mean the middle section of a video, I mean only the center
part of a single image (png) that will be overlayed onto a background,
such that the left and right sides are relatively unchanged, but the
center of the image is stretched to fit the new size.
Do you mean a continuous zoom like image warping? I have a few examples
in my book (search for "image warping"):
