Is there a filter which creates a "scrolling" animation of an image, e.g. shifts the image to the right by so many pixels and wraps pixels that go off the right edge back to the left. I would like the filter to repeat this so that in the end there is a nice scrolling effect when played back via Filter/Animation.

link in xenoid's answer does not wrap. However, I just recently wrote (I meant like 5 minutes ago) one that wraps layer and scrolls only the active/selected layer. https://gimplearn.net/viewtopic.php?desc=Scrolling-and-Wraps-layer-animation-Script-for-GIMP&f=3&t=414

At worst use a transparent layer for the layers you don't need. But the author is likely willing to write a single-layer version.

1Ok I just did
locate *.py | grep gimpand think I found the right plug ins folder. Hmm, still not working.– user9146Feb 14, 2017 at 23:23 -
2If you are on Linux or OSX make sure the file is executable. It should go into one of the two directories listed in
Edit>Preferences>Folders>Plugins(preferably the one in your home directory)– xenoidFeb 15, 2017 at 0:01 -
Ok, once I found the right folder, copied it there, AND made the file executable
chmod +x filename(Linux) it worked !– user9146Mar 2, 2017 at 15:48
There is a filter to do the offset once (scroll and and put pixels exiting on the other side) - but no ready made filter to animate that.
To create the animation you'dhave to write a small script that will:
call "offset" on a layer, copy the result, paste as new layer (on the same or on a new image, containing only the animation).
In my answers here and on stackoverflow regarding GIMP there are some examples and instructions on how to that programaticaly.

Instead of just providing links why not make your answer better and provide an example? I would upvote this if you had an example.– user9447Feb 14, 2017 at 18:42

time constraints. and repetition. The informatin is there - this is not a duplicate question, but I'd have to rewrite a lot to get an working example. If you do that, I will be pleased to upvote our answer.– jsbuenoFeb 14, 2017 at 18:44

Thanks. I should be able to solve the problem from this :-D– user9146Feb 14, 2017 at 18:48

Ok. Don't misinterpret me, I'd really like to write down a more complete example as DarthVader suggests.– jsbuenoFeb 14, 2017 at 19:16

If you get time that would be great, but I'm pleased for your direction. Thanks.– user9146Feb 14, 2017 at 20:14
