 I'm looking for some morphing software, to take two images, and

transition from one to the other.

One such program is the convert-command, which is part of the
ImageMagick-package.

It can do primitive shape morphing, for more information go here:

http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=11263

I've used convert only to do fade-morph frames between images taken of
the same view, which then are fed to mencoder to produce a video.

I can publish the shell-script which I created to accomplish this if
you're interested?

I Appreciate the offer, and you probably should publish for people looking for a fade solution, but I'm really looking for a full shape and color morph. I have an old program which I pulled off a Win98 machine which did a pretty good job, but it uses gif format, won't run under wine, and generally is pretty impractical other than as a proof of concept.

I'm surprised at the lack, I'll keep looking. Search turned up a number of things which sounded hopeful but had serious issues between the description and the performance.

Thanks for the pointer.


with gimp
load image 1
on image 1's window select File->Open as Layer-> pick image 2
Open the Layers dialog
insert a Layer that is background color (call it Clean).
duplicate image 1's layer (Background).
Sort the layers such that you see
 image 2
 Background copy
 Clean
 Background
Delete Background.
on image 1's window select Script-Fu -> Animators -> Blend
set number of frames, blur and if you want it looped (no loop I think.).
hit OK.

There is probably a way that you don't have to play with the layers as I did above, and figuring out how to save each layer (frame) as a frame file is left as an exorcise for the reader (involves making successive layers invisible and saving a frame).

Also this was with gimp 2.2.12 so the names of the menus and scripts have probably been changed to protect the guilty. :)
