Hi, I have been working with the brush for several weeks in 3.0.2 with no problem. I am working in the layer mask to the right of a copied selection, as in the screenshot.
I am working with the black brush in the white part of the image, to remove the last traces of white which surround the pasted element in the second layer. So, the black brush should bring out the dark area which is in the original image under the mask .
If I work on the dark area of the image, nothing should change. If I run it on the white left over from  the mask (circled in the screenshot), it should expose the dark underneath. So it did for days.
Now the brush is milky as in the screenshot. My opacity is 100 both in the brush options and layers panel, color picker solid black.
I don't know what I touched, thinking of going to color gradient, what would be the default? Closed Gimp multiple times, redownloaded Gimp. Thank you.

On Windows 10 32 bit version I was amazed to see that the program is now located in the user data apps roaming folder.

This causes my Trend antivirus to refuse to print without being overridden and thinks it is ransomware when I try to open a file.

I am sure there is  a good reason for this but it escapes me.

I will probably need to revert to 2.10.

Hi,
just an hour ago I was using a Gimp 2.x version. I updated to gimp 3.0.2 and no image extensions were recognized apart for 4 o5 basic ones.

When I also try to export an image to a specific format file no extensions are provided.
I unistalled g3.0.2 and reinstalled a previous version 3.0 but the same behaviour is shown
I am on Windows 10

What's going on?

Hi 
I just installed gimp 3.0.2 and when tryng to open a PNG image I find that I receive the following message: "File type unknown"

Can somebody please help?

OS: windows 10

Installed GIMP 3.02 on Sequoia 15.4.1 on Mac mini M4, Dell U2724DE at 2560 x 1440 over TB4.
I have a black screen with menus that pull down and operate, but I have only a black screen with a vertical divider bar about 2" from left edge of screen. Opening know good .jpg(s) changes the filename under the menubar, but that is all. Same with File>New, I get a new filename but no image.

I searched the web for similar problems but am not finding anything.

I am new to GIMP and the computer as well (finally upgraded from a 2014 mini running Mojave and ... CS5   ). The Sequoia install is fresh/clean and I have manually moved all my data over. All the apps are also installed fresh. I tried and tried to use Migration Assistant but it brought over 10's of thousands of old detritus, e.g orphaned kexts/plists/etc. from long-gone apps dating back to a 2003 PowerMac G4! :cheapskate:

Bonjour,

[Pour commencer je pose ma question en Français, mais peut-être qu'il aurait fallu que j'utilise l'Anglais ?]

Ma question : je voudrais simplement retrouver la fonction "Photocopie" de Photoshop, j'ai essayé avec "Filtres" / "Détection de bord" / "Bord" , mais ça me crée une image à fond noir et lignes blanches, alors que je recherche une image à fond blanc et lignes noires, comme une photocopie noir et blanc...
Merci d'avance !

Yes, you should post in English, there are good web translation sites around. - rich

Quote:Hello,

[To begin with, I'm asking my question in French, but perhaps I should have used English].

My question: I'd just like to get back to Photoshop's “Photocopy” function, I've tried with “Filters” / “Edge detection” / “Edge” , but it creates an image with a black background and white lines, whereas I'm looking for an image with a white background and black lines, like a black and white photocopy...
Thanks in advance!

I am looking for ideas and suggestions on how to use Gimp to modify photos for marquetry. I have turned photos into marquetry by hand. I draw outlines around different colars, transfer those outlines to veneer, cut them out on a scroll saw and assemble into a "painting in wood". An example is included below.
I am now trying to transition from hand cut to laser cut as the laser can deliver much more detail than I can do by hand. The laser requires a vector graphic of the lines to be cut. I am using LightBurn software to produce this vector graphic from a bitmap graphic. LightBurn has a great ability to outline different colors or shades of black & white. The outlines are delivered in a new layer and can be used to drive my laser.
The problem I am having is the shades of color or gray scale are too complex and convoluted in my photo. So I am looking for a way to simplify the photo so the different shades have smoother borders and there are fewer shades, no more than 20, as each shade needs to represented by a different veneer.
I am hoping that a few of Gimp's filters might work for me, but have found them complex and confusing to use. 

I would appreciate any suggestions on how to use Gimp for this photo processing. This problem has probably been solved before and am happy to be pointed in the right direction. Thanks for any ideas you want to share. 

Yellow tones in second photo are artifacts of the conversion from jpg to a small png, as I have no yellow veneers.

As soon as I open the Hue-Saturation box... I see colors change in my image?! This is new.  Every level is at 0 in the window, yet it is doing some weird changes and seems to be desaturating all 'Magenta' right off the bat.

Gimp 3.02 is not stable and I just need to go back to an earlier version.

A Gimp newbie here. I searched for previous threads on how to install GMIC for Gimp 3.0 on a Mac, but found none.

I made the following attempt to install GMIC this afternoon. I successfully used MacPorts to install the latest GMIC package on my new Apple silicon MacBook Pro running Sequoia 15.4.1. Gimp did not show GMIC in Filters menu.

I found the gmic_gimp_qt file and moved it to the User/Library/Application Support/Gimp/3.0/Plug-ins folder. Gimp still did not recognize that GMIC was available.

Has anyone installed this plug-in successfully for Gimp 3.0 on a Mac running Sequoia?

Appreciate any and all comments, thanks.

On the second layer, first screenshot, after rotating the element with my mac pad, I clicked "rotate" in the tool window, just to see what happened. That created a floating layer, I don't know if I am really supposed to click on "rotate", after doing it manually.
Basically, what I need to do is removing the excess mask from my element, but the mask on the second layer is no longer active after creating the floating layer.  Is Gimp trying to tell me that I should create a new mask on the floating layer?
The screenshots order is inverted.
Do I necessarily need the floating layer after rotating? thank you
