Ways to cut out images

Fri May 03, 2019 5:58 pm

Not sure if anyone has listed the many ways to cut out images using gimp. I'll just list a few that I use and just learned of their existence. Feel free to add to the list.

*Scissors
*Select by Colors Tool (image needs alpha channel)
*Wand Tool
*Quick Mask
*Paths Tool
*Free Select Tool
*Color to Alpha
*G'MIC's Extract Background Preset (Contours)
*G'MIC's Split Objects (Testing->Garagecoder)
Those are the ways I know of when trying to cut out an image in gimp.

Here are a few more:
*ofn-erase-background.py by Ofnuts that removes the selected color, leaving a smooth edge.
*Script-fu-remove-hemera-image-bg-color.scm

There is the new foreground selection tool in 2.10 that uses either Levin or Global engine matting.
But the results I've had with it have been awful.
From what I remember, the rggjan gimp-matting that was forked in the portable Gimp 2.74 was better.

Color: Color to alpha. Improved from 2.8, removes single color perfectly if the edges have no any feathering.

Then there is the ofn-erase-background.py by Ofnuts that removes the selected color, leaving a smooth edge.
Script-fu-remove-hemera-image-bg-color.scm by Rod is similar.

I knew about color to alpha, it just slipped my mind and I forgot to add it to the list. As for the plugins, I haven't heard of those.

Can try G'MIC's extract preset; pretty powerful. Not quite GIMP specific, but to me, GIMP cannot be without G'MIC. :)

I've used G'MICS extract preset. I will add that to the list.

Thank you for this! Very timely! I was watching a video yesterday on various ways to do this in Photoshop, and wondering how it could be "ported" to GIMP.

Does it mean we still don't have rggjan-level foreground selection tool in open-source products?
