Disproportionate torso to leg length correction - NickPearl - 07-28-2026
I have the picture of a man with disproportionately long legs (compared to his torso):
https://i.ibb.co/zVzt8HL6/zz-GIMP02-01.jpg
I need to use the GIMP software to lengthen his torso, and shorten his legs without changing his overall head-to-toe height and without touching his head and face.
I asked artificial intelligence (Google Gemini) about this and it suggested the use of the Cage Transform tool:

However, when I do this, it creates some crack lines or fault lines (or whatever you may call them):

How can I avoid this problem?
And first of all, is the cage Transform tool even the right tool to use for this?
How can I correct the disproportionate body image of this man?
What tool to use and how?
Please advise.
Thanks.
Nick

Only way I can see to do it would stretch his arms

Another minus for AI
I would consider the gmic_gimp_qt plugin http://www.gmic.eu and the interactive warp filter.

Goes like this:
(1) Make a suitable selection
(2) Bring up the gmic plugin, find Warp (interactive) and and for this set maybe a 4 x 4 grid. Ok that and it brings up...
(3) A floating window where you can drag those grid points to deform the image. When finished close the floating window and the result is sent back to the Gimp canvas.
(4) Careful with the amount you stretch or the arms will look weird (but not as weird as the original)

Thanks for your help.
Is that a separate, independent application that rivals GIMP, or an add-on that gets hooked up to GIMP?
If that is an add-on for GIMP, then when I go to the web page that you provided
https://www.gmic.eu/
should I click on the Download button on the left panel on that page, or should I scroll down to the section "2 - G'MIC-Qt," and clock on the "download ..." link on the bottom of that section and download from there?
And after i install that, where in the GIMP interface will I find it?
Please advise.
Thanks again for your help.

Just install this version, gimp will find the gimp plugin and you find it in the gimp menu 'filters':
