Hey everyone! I've been using GIMP for a couple of years now, and on macOS I have never had any issues. I know macOS Gimp isn't getting updated yet, and hopefully when GIMP 3 comes out the issue will be fixed, but still think I should report it here. I've been using Photoshop for extra things, but Gimp is still my main. But, recently, a major problem has been occurring. When I usually open GIMP, the colors are fine, but after I open a image (not create), they usually look like this.

I can change the color, but the pink stays. The original image imports fine, but after that, anything to do with colors goes downhill. Here's a image technically filled with bright red.

This is really annoying, and I can't find any fix yet. I work with importing multiple images, and working with a lot of layers. This is where it gets even harder.
Here's the original image, everything appears fine.

Here's the image after imported into GIMP. It loses basically all of it's color, but isn't completely black and white. This issue has occured over multiple macOS High Sierra installations and multiple GIMP installations. If anyone knows a temporary fix to this, PLEASE, let me know. Hopefully this will be fixed when the next version of GIMP gets released for macOS.

Hi,
I've taken a few HDR screenshots with Windows Game Bar. They are in the .jxr file format. I can load them in Gimp but there's a message that the HDR colors will be flattened. Is there some way or something planned to load them with HDR support?

I'm looking all over the internet to find a way to convert .jxr to .avif format with HDR colors but so far I've found no (free) way to do that.

A very short basic description of Ofnuts   addonCollectionManager  for managing resources brushes, dynamics, gradients, palettes, patterns, scripts (.scm not plug-ins), and fonts although fonts are problematic in Windows.

Download from here see: http://sourceforge.net/projects/gimp-too...s/scripts/

addonCollectionManager-3.0.py down the list look for date 2013-05-26

There is a description of the setup here: http://gimp-tools.sourceforge.net/managementtools.shtml

Concentrating on a  brush collection setup. (others are similar except fonts)

Make collections of similar brush themes as a zip file. Use any recognized brush types. Single .abr brushes can be zipped or included with other types.

The zipped 'themes' go in a folder  
Windows: C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\brushes_storage
Linux:  ~/.config/GIMP/2.10/brushes_storage

The addonCollectionManager plugin is enabled from a right-click in the brushes dock.
Choose the set(s) Click on OK. the sets are added to the brushes dock. They can be filtered using the zip-file name.
Either leave the  addonCollectionManager  dialogue open, it will be hidden behind Gimp or close it.
Removing / adding more brush sets: Open the  addonCollectionManager  dialogue, untick / tick  any changes and OK.

   

....and a short animation: resourcemanager.mp4

Select with lasso. Then turn the tool option to "add " (or subtract) and you will no be able to select, clicking is null, does not create a new selection path.
Workaround: switch to rectangle selection then back to lasso and it works.

Trying to save space I decided to convert some .abr brushes to .gbr.

So I ended up checking that in the .gbr format the file is gigantic, almost the size of the set in .abr 

My experience was as follows:
With a .abr set containing 15 brushes, I converted all 15 brushes to .png.

I compared the fidelity of the brushes created in .gbr via the images in .png and via direct conversion of the brushes into .abr by Gimp. There was no difference, even the final size and visually I did not detect any differences.

The .abr set is 37,844 KB (36.9 MB)

I chose Brush015 from this set to make the comparison.
In .png this brush015 was left with 3,471 KB (3.38 MB)
All .png together add up to 42.6 MB

Only brush015 converted to .gbr had 29,445 KB (28.7 MB); little less than the complete Set .abr.

Even if I only wanted two brushes from this Set, they would still end up taking up more space than the 15 brushes from Set .abr.

I tried to convert some of my .gbr brushes to .abr, first converting to .png and then using PS CS2 creating the .abr. But the version I downloaded, although apparently free, does not offer the Edit - Define Brush menu.

The question is:

Is there any other way to create .abr other than through PS? Some other software

I am nearly certain I am saying this wrong, but I would like to increase the contrast of the selection tool border. This could be by changing it's color or some other method. My eyes are not what they used to be and I sometimes have trouble telling if I have everything I want selected inside the selection area. To be clear, I am talking about the dashed black line that appears around the selection. Ideally I would be able to modify it for the paint brush tools as well, but that is a less serious issue for me generally and easier to fix.

In typical applications I would expect to find a properties window somewhere that I could modify these, but I have not been able to locate anything.

I have been having a problem with JPG files exported via GIMP.   The thumbnail  (always) and sometimes also the actual JPG file once opened in other applications or back in GIMP turns very dark, as if brightness was turned nearly all the way down.   

Any ideas what setting I need to change or what I may be doing wrong?

I have a digital scan of an old sketch ( a colourful flower with a background). It has a border around it that has yellowed because it's quite old and at the bottom of the border is the title of the painting, in handwritten cursive font (it looks like it was done with a pencil). My problem is that the title is quite faint and I am having trouble clearing it up without affecting the rest of the picture. I attempted to use the burn tool to go over the handwriting but this was incredibly time consuming and not quite effective. I also found that the burn tool slightly change the yellowed colour around the writing as well. I tried to play with levels and achieved a great, clear title but it severely darkened the rest of the picture to the point where it was almost black. Is there a was to do this by isolating the handwriting in some way? I'm new at this, please be gentle!

I learned how to make a single brush .gbr file. Is it possible to have more than one brushes in a single .gbr file ? ie, a brush pack .gbr file.

Something with 5-6 brushes which can act as a single brush inside GIMP but can be installed using one .gbr file. Thanks.

My friend sent me an image saved as a .pdf file made in Photoshop.

I loaded the image into GIMP and made a very small change to the image.

I would like to save the file once again as a .pdf file and NOT LOSE ANY image quality.

The file sent to me was approx. 4M. When I save the file in GIMP the file size becomes approx. 312K, or less than 1/10 the size of the original file. When I look at the two images, the GIMP image has lost quality.

Can someone please tell me how I can do this? Thanks!

....
More info.
I also have the same image file as a .tiff file (coming from Photoshop).
When I open the file in GIMP and edit it (small edit) I can save it as a .tiff
and the file size remains the same! Approx. 4M.

But, when I try to save it as a .pdf file, the file size becomes approx. 312K !
How did my friend save it in Photoshop as a 4M .pdf file,
and how can I save it in GIMP as a 4M .pdf file?
