Usually when I open the tool for changing levels on a picture nothing happens until I press ok.
Lately as soon as I open the tool the picture turns an ugly blue and will not do anything else.
I did find out that my 'preview' was turned off but I check that it's on everytime now and it has stayed on since I checked it again. What could be wrong with my levels tool?
I normally use it for correcting colours but now it just wants to do it own thing!
I only updated my gimp to 2.10.34 (revision 2) a couple weeks ago, surely its not this. It has worked ok and has just changed in the last couple of days

EDIT: Made a new gimp file by renaming and restarting gimp and it looks ok atm

Using GIMP 2.10
When I choose print from the menu a dialog opens and I choose my printer from the list.
When I click on "print preview", my pdf reader opens. The dialog from the print plugin does not open. The print plugin is installed. I cannot find a setting to change this. My previous version of GIMP did not behave this way.
I am using linux and recently upgraded to Magiea 9, but I do not see how that would have an effect.
The GIMP I am using is a package from the distro.

Thank you

Hi all,

I recently installed GIMP on my new Mac Mini with Sonoma OS and on start up of the machine, I receive this message every time on Terminal:

Last login: Sat Oct 28 09:46:13 on console

/Applications/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins/file-jpeg/file-jpeg is a GIMP plug-in and must be run by GIMP to be used

Has anyone else had this issue and know what it is? Do you know how to correct it? If anyone knows how I can stop this coming up each time, I would appreciate the information. I ran Gimp on my old machine, also a Mac Mini, but I never had this issue. 

Thanks in advance,

Tony

Hi,
I've studying Python Fu code, and I came across this function call:

For speed, I tweak colors on negatives I've scanned at only 600 PPI.  Then I need to get the same results on the same negatives, but on images after scanning at 3200 PPI. Is there a way to transfer the results of the adjustments I made on the 600 PPI negatives to the 3200 ones?

Hello everyone,

Written words will only do so much in explaining this situation, so I made a video recording: https://www.youtube.com/watch?v=tBoZ711TqQw


The issue: I draw a circle with the circle selection tool and fill it with black. Its layer is placed below the transparent image, behind which it should function as a background.
However, the black lines in the front image suddenly show white, as if some type of layer mode has been applied, which is verified not the case. Again, you would really need to see the video to truly understand this issue.
I'd be most grateful for a solution.

Thank you kindly,

Jop

I use PNGs because they are lossless.  I know the compression level with JPGs affects the quality but not so with PNG.  Is the only disadvantage with using the highest compression (9) with a PNG is that it takes longer to save?  What about decompression?  If a PNG is saved at 9 does it affect how another program opens the file?  If one wants to minimize file size is there any reason other than extra saving time not to use the maximum compression?

Hi, I'm pretty new to gimp plugins, and I wanted to play around with developing some specific plugins for my project. When I run vscode, however, pylance does not detect gimpfu. That's weird, since my interpreter is set to the python version in GIMP's bin. Additionally, the plugins do work when I run them in the application, so gimpfu exists somewhere. But without any familiarity with the documentation, developing kind of feels kinda blind...

GIMP version: 2.10
Python path: C:\Program Files\GIMP 2\bin\python.exe

Is there any way I can fix or troubleshoot this problem? I'm not sure where to start. I'm trying to see if gimpfu can work in WSL, if that works I can just move the plugins over to Windows. Thanks in advance.

Hi guys,

I know how to do a sphere (sphere.png) and a grid (grid.png), but how can I do that (the 2 last pictures). I am new to Gimp, and I don't have any idea how to do it (pic01 and pic02). 

Thank you

Hello GIMP Folk -

I've used GIMP for simple photo work for several years, but I've just encountered a PROBLEM.

When I have opened a photo in the past, a little dialogue says something like: "Drag your cursor to crop image."

This has disappeared, and in its place there is now a tool makes the image to be worked on LARGER... and LARGER - and no selection occurs!

Thinking perhaps my trusty GIMP had developed a glitch, after switching off & on my machine to clear the problem, I deleted GIMP and installed the latest 2.10 version.

But - Same problem. I cannot use my cursor to make a simple selection / crop of the image.

What has happened?

Any help will be wholeheartedly appreciated!
