  Selective transparency
Posted by: aka - Yesterday, 03:40 PM - Forum: General questions - Replies (4)

Hi,

Look, please, at the following image:

   

I wish to transform the big black area in transparency (but not the hair of the girl  Smile  ), and very important:

  • I need to draw the visible areas with my mouse,
  • I do not wish to work by deleting the areas that are going to become transparent.
Can someone have a way to do that ?

Thanks

  Can you identify effects/filters used on this image?
Posted by: aye123 - 01-29-2026, 10:23 PM - Forum: General questions - Replies (11)

Hi. 

Long time ago i created an image on GIMP but it was over 10 years ago (exact date between 2010-11), ever since that time i havent used GIMP once, forgotten all about how to make images and now i want to recreate that original effect. 


https://ibb.co/chrGw64d

(tried to insert an image, but it doesnt work for some reason)


Top image is my recreation, bottom is the original effect that im looking for.

As you can see on the original, there is some sort of spiritual/smokey kind of filter that i want to recreate. You can clearly see that violet color isnt flat and there are different shades of it throughout the whole text.
I have no idea how i achieved that in the first place. I was able to recreate the neon effect as it was pretty simple and there was a tutorial for it, but that particular effect im looking for - i have trouble to even accurately describe it. 

Another thing is that i have no idea how on the original image the X lines reach B and U. I was looking for the exact font and the best possible match that i could find was Espectro Swash, but i dont know how to recreate that effect.

Its just my educated guess, but i think that the effect im looking for could be some sort of font filter, if something like that exist/existed.

When I import a pdf image in Gimp, a grid appear even if I don't active the grid view in the toolbar. The grid is still there when I export the pdf from gimp. Do you know how to suppress this grid ?
Thanks for your help

  GIMP 3.0.8 Installation
Posted by: tb75252 - 01-28-2026, 04:45 PM - Forum: Windows - Replies (2)

I have just installed GIMP 3.0.8 (64-bit) on three PCs, all of them with Windows 10 (64-bit), v. 22H2, OS Build 19045.6466.
GIMP does not launch on any of the three after double-clicking on its icon.  It briefly displays a small blue spinning circle and nothing else happens...
Is there a trick to launching GIMP on PCs that run Windows 10?
Thanks.

  GIMP won't start after fresh install
Posted by: Mark-GIMP - 01-26-2026, 06:28 PM - Forum: Windows - Replies (2)

Title says it all.
I've been using GIMP for more than a decade on a few computers.
This time a fresh install doesn't start.
Absolutely nothing.

Suggestions?

  Display not keeping up with image changes in plug-in
Posted by: nmw01223 - 01-25-2026, 05:42 PM - Forum: Extending the GIMP - Replies (2)

I am new to writing plug-ins - I've only done two. They are python on Gimp 3.0.6, running on Windows 11.

This one opens an image from a file and then assigns a display as follows:

Code:
    infile = Gio.File.new_for_path(os.path.join(img_folder, img_name))
    img = Gimp.file_load(Gimp.RunMode.INTERACTIVE, infile)
    disp = Gimp.Display.new(img)
This all works, it shows up on the display.

Then, the display is resized, new values are calculated:
Code:
img.scale(new_width, new_height)
It is then written out to a JPEG, rescaled again down to thumbnail size, and written out again.

Then the image is cleaned up and the display deleted, which removes the image as well.
Code:
img.clean_all()
disp.delete()
Then the whole process starts again with a new file.

It all basically works fine, the JPEGs turn up OK. But, as the images are progressively shrunk, the display doesn't keep up. Basically, it's hard to describe or show, but just pieces of the shrunken images show up. I could if necessary try to video it.

But, if I run the commands one by one in the python console, no problem at all, it all looks fine. I assume this is because it is done slowly. The display is probably on a diffierent thread and isn't getting a look in when running at speed.

It isn't a show stopper, the files are fine, but it looks messy.

Is there a way round this, flushing all the display commands, for example,? Cannot find anything in Gimp.Display.

  script-fu examples - batch export
Posted by: rich2005 - 01-24-2026, 09:56 AM - Forum: Extending the GIMP - No Replies

This is a script-fu batch plugin. https://www.maxbronner.dev/blog/dev_2025-03-26
and for a download https://github.com/max-bronner/gimp3-ima...ort-plugin

The only comment I have on that is for linux make sure that batch-export.scm is made executable.

It scales then exports opened images in a variety of formats.  That might not be what you specifically want but it is relatively clear as to the export syntax which is useful.

  Safe Technique to Unlock PST File on All Windows Versions

I am unable to access my Outlook PST file because it is password-protected. I have tried opening it on various Windows versions, but the issue persists. Is there any safe and reliable technique to unlock a PST file on all Windows versions without risking data loss? Please suggest a practical solution.

Star Perspective tool anchors.
Posted by: LeonardCarlCampbell - 01-23-2026, 09:53 PM - Forum: Extending the GIMP - Replies (7)

When using the perspective tool to modify an image that needs much adjustment the process could be made better. It appears that the perspective tool anchors the original corners of the picture except for the one you are changing even after they have moved. Doing it this way causes the alignment of the other corners to change requiring you to readjust them (sometimes more than once). Wouldn't it be better to anchor the other corners on the new corner of the picture so they don't require readjustment after set? (Hope that makes sense). Or have a button for that option. First picture is original, second is first pass, third is second pass, 4th is final.
