  Drag & Drop in Layers Not Working
Posted by: blgriffin83 - 03-13-2025, 06:24 PM - Forum: General questions - Replies (2)

For the longest time my drag and drop hasn't been working in the layers. When I grab the layer it moves across the screen as it should but for whatever reason when i drop it just doesn't move. I have been having to move layers around using the arrows at the bottom of the panel but I cannot use layer groups because I can't drop and drop layers into the group. I have tried resetting to default as well reinstalling GIMP. 

Anyone else have this issue?

  Automate croping without reducing original image size
Posted by: mrcoffee2000 - 03-13-2025, 01:01 PM - Forum: General questions - Replies (2)

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.

  Making a Selection from a Channel
Posted by: cloudescaper - 03-13-2025, 11:23 AM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (3)

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

  Display problem in Gimp 2.10.38 (revision 1)
Posted by: beaubrunb - 03-13-2025, 10:27 AM - Forum: OSX - No Replies

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.

Gimp 2.10.38 (revision 1) on a 15-inch Macbook Pro Retina

This is my first scm script-fu for Gimp 3.0 rc3 & 2.10 that uses G'mic, I had to wait until there was a version of G'mic for Debian 13 Trixie where there is Gimp 3.0 rc3.

  Exported jpg different than what GIMP shows
Posted by: Sygon_Paul - 03-12-2025, 09:32 AM - Forum: General questions - Replies (6)

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.

  Crosshair guides for the v3 dialect of ScriptFu.
Posted by: teapot - 03-11-2025, 03:11 PM - Forum: Extending the GIMP - No Replies

Further to Rich's post here:
https://www.gimp-forum.net/Thread-How-to...3#pid43283

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.

Code:
#!/usr/bin/env gimp-script-fu-interpreter-3.0

(define (add-guides image drawable)

  (let* ((drawable-width (gimp-drawable-get-width drawable))
         (drawable-height (gimp-drawable-get-height drawable))
         (offsets (gimp-drawable-get-offsets drawable))
         (offset-x (car offsets))
         (offset-y (cadr offsets))
         (position-x (+ (/ drawable-width 2) offset-x))
         (position-y (+ (/ drawable-height 2) offset-y)))

        (gimp-image-add-vguide image position-x)
        (gimp-image-add-hguide image position-y)))

(define (script-fu-crosshair-guides-v3 image drawables)
    (script-fu-use-v3)

    (gimp-image-undo-group-start image)

    (do ((len (vector-length drawables))
         (i 0 (+ i 1)))
        ((= i len))
      ; (gimp-message (string-append "i: " (number->string i)))
        (add-guides image (vector-ref drawables i))
    )

    (gimp-image-undo-group-end image))

(script-fu-register-filter "script-fu-crosshair-guides-v3"
    "Crosshair Guides v3"
    "Place crosshair guides on all selected drawables."
    "teapot"
    "teapot"
    "2025"
    "*"
    SF-ONE-OR-MORE-DRAWABLE
)

(script-fu-menu-register "script-fu-crosshair-guides-v3" "<Image>/Image/Guides")

Information Non-destructive editing in Gimp3
Posted by: Ofnuts - 03-11-2025, 01:20 PM - Forum: Tutorials and tips - Replies (6)

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. 

   

This can be useful. For instance, in the image above, you can tweak the denoising and not lose the Exposure correction or the sharpening (and given that the trick is usually finding the right blend of denoising and sharpening this makes the workflow a lot more efficient). You can also decide that you will do Exposure before everything else by moving it down in the stack.

Whether the filter is applied immediately or added to the stack is set by a "Merge filter" check box in the dialog:

   

When the box is checked, the filter is applied immediately. This box only shows when you start the filter from the regular menus. If you edit the filter in the filter stack it is implicitly considered as "unmerged". 

If you apply the filter immediately it is applied before the filters in the stack.

  Select By Color tool
Posted by: meghan_e - 03-10-2025, 11:48 PM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (2)

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!!
