Hi All,
I'm new to gimp, but wanted to know if there's a way we can scramble images using the program. We are trying to make images unrecognizable through scrambling (while still retaining the image colors,etc).

Not sure what you really want to do.

1. There is no "Scramble" Menu item in gimp

2. Images can be scrambled/descrambled with ImageMagick (convert with the encipher/decipher options)

3. There are other scramblers around, but none as a plug-in for gimp afaict.

I don't think Gimp has that capability but you could always encrypt the picture file with TrueCrypt or PGP.

Hey Kathleen,

There's so many ways... What to do depends on what you want the output to look like, and the scale of "recognizable" elements you want to make "unrecognizable." Things to play with include:

Filters > G'Mic > Arrays and Frames > (various array effects)

Filters > G'Mic > Deformations > (various deformation effects)

Filters > Map > Resynthesize

Filters > Artistic > Glass Tile (and others)

Filters > Distorts > Mosaic (and others)

And more. Explore, play around.

:o)

I think maybe the word you want here really might be blurring?

Or do you mean randomly moving pixels around?

"Scrambling" also has a meaning in cryptography, which some people have taken to mean you need to be able to restore the original image exactly, is that something you need?

We are having to guess because you have not given us enough information. An example might also help.

Note, if this is for any sort of privacy purposes, that most such "scrambling" methods can to some extent be undone. A warped face can be unwarped, blurs can be unblurred, etc. If the purpose is to hide someone's face or similar, fill a circle with some colour instead. Or if you want to keep similar colours as the rest of the image, use Resynthesizer to grab colours from the surrounding area.
