I would to a script but kaleidoscope has many options that lets you preview the result before applying so a script it not really useful here to automate all that as users might want to play around with kaleidoscope settings first as it's more flexible to do it manually.

If not a script, then perhaps a tutorial would be nice???

1st duplicate the layer and work on the second layer. You can use the settings I posted earlier and save the preset as "Frame". You can tweak it a bit to your liking. Then go to layers\Transform\Offset and click the divide by 2 button. Then delete the middle empty section.



Here's the ScreenCast tut:

Good idea sallyanne...I did save the kaleidiscope settings as a preset....thanks for the suggestion...

Great tut, racer-x...that will help a lot people...

I've still been playing with it....


This is the same image using G'Mic, on the Stained Glass setting...

What a great idea. Thank you for the settings racer-x. Love the stained glass FlutteringBy.

For this go I've gone for simpler corners by setting Centre X to 1 and drawing diagonal lines by hand.

I also found if you do the original frame twice before offsetting it will be thinner

Thankyou FlutteringBy for this thread, racer-x for the tutorial, 2-ton for asking the question and sallyanne and teapot for your input, I've had great fun so far...

What a lovely idea for making frames.

Great suggestions & images everyone... ....

This is one of those tuts that the more you work with it, the more idea's you get... ...and some images will produce a more vibrant frame, like this one....

Really lovely results from everyone

Have stumbled on a frame with more than 4 sides but forgot to keep the source picture

Great frame teapot...I snagged a copy & changed the background color...



Many thanks... ...

Yes, thank you all!

RJKD, thanks to the link that you made available in GimpLearn I might have been aware of this post. Thank you very much!

Thank for presenting the next method of creating frames.

My method for creating unusual frames using paths (in short):

1. Create any path
2. Path to selection
3. Select -> Shrink
4. Selection to path
5. Splice strokes in visible paths (two path) - older version plugins Python by Ofnuts - but it works very well
in GIMP 2.10 (ofn-Path-Splice-Strokes-0.1.py - in attachment)
6. New spliced path to selection
7. Fill to color or pattern, or gradient
8. Select none and an additional effect (e.g. 3D Extrusion, GT Bevel, G'mic ...)
... and further elements in the frame - repeat from point 2 ...

Thanks for your suggestions MareroQ... ...

Hopefully I'll have some quiet time during the holidays to give it a try....

I didn't resist, I had to try

Tried this several times today but cannot get it to work in 2.10
EDIT: I got it to work with one picture but another using the same settings I get only colour in the corners.
