I desperately want a tool that can stretch a selection or layer in a
curvy sort of way on the main window, because I frequently want to
place images inside of other images in such a way that the
scale/rotate/perspective tools are not sufficient, nor are the curve
bend or image warp plugins. Speaking of the rotate/etc tools, when
shifting around, the thing is shifted as an opaque thing, rather than
with its actual transparency, which is very irritating (i've only used
the Gimp up to 2.2.11, maybe its different later?).
So then, what is the easiest way to add a kind of transform tool that
stretches the current selection based on a cubic tensor product patch?
I read a post somewhere in the archives that said it was mostly "easy"
to add new tools. So what does "easy" entail? I've only spent an hour
or two less'ing the gimp source, so I'm still not too sure yet what's
what. Is there any one else remotely working on such a thing?
I have already implemented something of the kind in a (somewhat rough
and unpolished) program called Laidout that involves subdivideable
patches, of which you can see screenshots here:
I envision a dialog something along the lines of this mock up:
My actual rendering routine is currently a major hack to get it off the
ground, and is totally inefficient. It really needs coding from someone
who actually knows something about rasterizing cubic tensor product
