  Antique Metal Qt 300 for Gimp 3.0 rc3 & 2.10... need G'mic
Posted by: vitforlinux - 03-12-2025, 01:43 PM - Forum: Extending the GIMP - Replies (1)

[Image: antique-metal-qt-300-ginp-3.0-2.10.jpg]

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.

Once installed, it is located in:
Script-Fu> Logos> Antique Metal GMIC QT Logo 300
Script-Fu> Alpha-to-Logo> Antique Metal GMIC QT Alpha 300

Il font OFL used is QTCaligulatype.otf .

  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!!

  How to use selecting multiple layers with the tranform tools.
Posted by: teapot - 03-09-2025, 07:07 AM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (9)

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.

  Text to path query
Posted by: Evans8773 - 03-08-2025, 01:47 PM - Forum: General questions - Replies (1)

Hi all

Just started using gimp again and have an issue I have had in the past but forgot how to fix it.  Applying text to a circle the top of the circle text along path does as intended but when I do the bottom half text it apples to the path like it is stacked and just looks like jumbled up spaghetti. Like I said this has happened before but cannot remember how to fix it. 

The initial text to path requires me to use the flip tool so it looks right but then after the flip I get spaghetti

Hope someone can help 

Cheers

  Print an image (2480x7016) on several A4 pages
Posted by: Fleshus - 03-07-2025, 10:09 PM - Forum: General questions - Replies (3)

As I saw on the internet, an A4 sheet would be equivalent to a 2480 x 3508 pixel photo in 300dpi. As I need two A4 pages for my project, I created a 2480x7016 image but GIMP (or other software) does not offer me to print on two pages.
So I cut this image in two with a selection rectangle and printed separately. However, the printed result does not match the preview of the image in question (I compared).
Can someone help me? It's incredible that in 2025 we struggle for something so simple...
