Hello,

I don't do much image editing in anything resembling robust software. Apologies in advance if I use terms that are incorrect (please feel free to correct me).

What I'm trying to accomplish - I routinely digitize archived paper documents that are oftentimes spiral bound or comb bound. I usually unbind these to get good scans. The problem is, the scans always show the edges of the paper and the holes left from binding. I would like to automate 'whiting out' the margins to erase these marks on the scans so I can get a cleaner scan for archiving. I want to retain the original image size so the contents of the document look like the original, including keeping original margins and whatnot.

I am using GIMP 2.10. I found the BIMP plugin and started messing with the features in that. It seems like automated a crop is pretty straight-foward with that plugin, but I don't see a way to retain the original image size. GIMP has options to retain the original image size when cropping an image. Crop may not be the right function to accomplish what I want, so any advice is appreciated.

Hi there, thanks for reading this!

I have an image (layer) in b&w  I want to use as a mask. In Photoshop, I used to make sure the layer is active and just press "strg+alt+2" or make a selection from the RBG or Green channel in one click. This gave me a selection that is hard in the bright white areas and softer in the areas where the light is less bright. I used this simple method to edit the highlights in my images with absolute precision, since I can paint on the b&w layer and exclude certain areas as well. It was so quick an easy and I was wondering if there is fast way to get the same selection out of gimp?

Thank you in advance

The problem is this.

When I try to open one of hundreds of images on my external drive and use Scroll, something really weird happens with the display. It only disappears when I hover my mouse over the file list.
Look at the screenshots.

The problem is even more obvious and annoying when I'm working on an image. Especially when I scroll or zoom...
Could someone explain how to fix this display bug?
Because it's really difficult to work comfortably.

Hello! I spent the last few hours adding an alpha channel and removing the bordering white from an image. When I exported in GIMP as a jpg, the end file still has the white. I do not know enough to tell if this is a jpg issue, a GIMP issue, or a user (me) issue.

If this is an issue with jpg files, how can I work around this, as I need jpg? I can try other image formats, but would prefer jpg because LibreOffice Writer doesn't like png format.

I am using GIMP 2.10.38 on Windows 11.

Attached is the exported jpg file. I can't seem to be able to attach a second image, so I will attempt to reply with that.

Further to Rich's post here:

I was finding the Filters -> Repeat and Filters -> Recently Used sometimes greyed out for the old script. So here's crosshair guides written for the v3 dialect of ScriptFu. It puts crosshair guides on the selected drawables.

Gimp V3 introduces "non destructive editing" (aka NDE).


When you apply filters to layers, instead of altering the layer pixels immediately  (as done in V2), the filter can be added to  a stack of filters which is applied on the fly when Gimp uses the layer contents. When this is the case there is a "fx" icon next to the layer, and if you click on it you get the stack of current filters, that you can further edit. 

   

   

I've been working with Gimp 2.10 for a long time. I'm not a Gimp expert at all just like playing around.
Anyway, I installed Gimp 3-R2 and was trying to do a simple
transparency layer -> Filters -> Render -> Noise -> Solid Noise.
Then I went to the Select By Color tool and it won't select anything.

I tried these exact steps in Gimp 2.10 to be sure and it works fine.

Is there something else that needs to be set up? If there are instructions, I'm happy to read them, I just haven't been able to find anything about it.

Thank you!!

Hi, I'm just tying to understand the details of selecting multiple layers. I get that you can do this with shift or ctrl keys. If for example you wanted to rotate three layers, what's the rule to say which one is used for the "preview" while you are adjusting the rotate?

In gimp 2.10 you could link the layers and choose which one is active so that's the one that's used while you are adjusting the rotate.
