Hi!
Hi designed i simple "shutter" with GIMP, a layer painted with a brush and a level of opacity say of 30% I think. I saved the image in .png so I can import that image in an another program I use to work with gif animations.
I use no one, one or more of this shutter on each gif I work with.

The question is: If I have to remove the effect of the opacity layer I added to the gif animation as part of the workflow and I have the original .gif I can think of materially import in GIMP the original gif and the new one, and work some magic by confronting each and every frame of the two animation, one at the time...never ending story!!

So: There is a system to automate the process with gimp, confronting the new and variously worked gif with the original, maybe applying on the way a mask in small zones so in those zones they stay in the new form?
Thanks for reading me, hope to be enough understandable.

Thanks to all, have a nice day, night etc.

I've got an old Dungeons and Dragons map from I was a kid and I'm trying to remove the drawing/pen (which is black/grey at varying degrees) from the off-white/blue-grid-graph-paper that it was drawn on. What's the best way to go about this?

For a making weird text one can use the 'spacetypegenerator' :
https://spacetypegenerator.com/index.html
One can transform a text with a bunch of sliders and if one is satisfied with the design, one can make a screendump and load it in gimp. (File / Create from clipboard)
To remove the background (if necessary) white or other colors in gimp :  Colours / Colour to Alpha 
By clicking on the 'select button' (top right) one get different generators.
   

The Polar Coordinates Filter sometimes leaves a 1 pixel seam. This often occurs after editing an image which consists of two layers which are merged to one layer. The gap can be avoided by marking the "Map backwards" option. However, this workaround sometimes enforces another correction afterwards. Is there a known approach to handle (i.e. avoid) this 1 pixel seam problem?

Im currently using Gimp 2.10 on macOS Big Sur Version 11.1.

Hello, there! I'd like some help setting an image for a Instagram profile. Everytime I upload it the image get distorted around the white name and the inside picture. I looked for some tutorials on Google and so on, tried some filters but I can't solve it.

I usually use Gimp to clean up photos of miniatures.
Normally i do the following thing drag and drop the photo into gimp, then click colors, levels and then auto.
There done, maybe do a few corrections here and there, but normally that is it.

Well for some reason Gimp won´t do that anymore.
I have tried opening its as administrator, tried to opening it through files, cutting out the relevant part of the photo and copying it the new page, Reinstalling it nothing helps.
Gimp simply treats my picture as if it isn´t there, anyone know how to fix it?

I am running the latest version of Windows 10.

Anyway to mirror a brush in gimp 2.8?

is there maybe a plugin or something to use a brush in a symmetrical way?

I want to take a screenshot of an app, but not so that the screenshot can be viewed full size.

I just want to show off the app w/o giving away too many of the details of the controls. And if someone tries to expand the size, it will be unreadable.

I will then post these screenshots on it's website.

Can anyone point to how that might be done?
