Bonsoir,

La question est dans le titre (je n'ai pas pu faire plus court...) : dans Fichier>Ouvrir, est-il possible d'avoir des grandes étiquettes images ? Car apparemment, par défaut, on a à gauche la liste des photos et pour les visualiser à droite il faut cliquer dessus une par une :

   

Y-a-t-il moyen d'avoir directement une sorte de "planche contact" de toutes les photos du dossier ?

Merci d'avance !

PS : lorsque j'édite ce post, l'orthographe devient aléatoire, désolé...

I have the latest 3.0.4 vs of gimp. What happened to the scroll bars, horizontal? They were there in the other vs 3's. I haven't had to do anything to make them appear usually. Do I have to this time?
I also do not have the status menu bar at the bottom - where I can change the view size etc. Even the layers icons in the dialog are missing - could be my whole bottom is missing. I cannot check now.

EDIT:
oops, now I have no menu bars at all. I did click on merge menu bars earlier. Only way I can shut gimp down is do it from the icon that shows up in my task bar. If that is the case how can I undo it as I cannot get to edit > preferences now.
Closed everything down and reopened and its all there now

A quick try (on the right the original) :

   

I've just started using GIMP (2.10.14) after using an old copy of Photoshop for years (decades). So, my general knowledge of image editing is OK, but my knowledge of GIMP - zero.

So, very dumb question, want to scale the pixels/inch of an image. I've got a scanned image (B/W, TIF) that is very long and thin - one of those old school pictures taken with a panning camera. It was scanned and stitched together at 1600ppi, which is really way too big for my needs. So, want to down convert it to 600ppi. Should be simple ... .

So, started GIMP, dragged the image in, and it loads OK. Go to scale image and it shows the image as roughly 58000x8000 pixels at 1600ppi X and Y. X and Y are linked, so change X to 600ppi, and, yes, Y changes to 600ppi. , Click scale, so far so good.

Export as TIF, writes OK. But, load it up again, and it still says 58000x8000, 1600ppi. Same size file, too.

So, tried again, but this time just saved it as its native format, and reloaded it. This time it said 600ppi - good, but still listed the overall resolution as 58000x8000 - which it clearly wasn't or there would have been a lot of blank space.

Confused, should be very simple, what am I doing wrong?

Hello everyone,
I'm new to the forum. 

I'm having some problems with GIMP 3.0.4 (Flatpak) installed today on my PC with Linux Mint 22.1 Cinnamon.
Until two days ago, I had version 2.10.36-3ubuntu0.24.04. However, since yesterday I have been unable to use it: when creating or opening an image, the various mouse cursors (brush, selection, etc.) remain confined to the left side immediately after the toolbar and there is no way to do anything. After searching in vain, I purged GIMP (sudo apt-get purge --auto-remove gimp) and installed the Flatpak version.

Now, these are the problems I have: 

1. When I went to Edit>Preferences>Folders>Brushes, I saw that there are 2 folders, but when I try to open them, it tells me that the folder cannot be found. The folders indicated are these:
   /home/franz/.var/app/org.gimp.GIMP/config/GIMP/3.0/brushes
   /app/share/gimp/3.0/brushes
   I went to check and, indeed, under the folder /home/franz/.var/app/org.gimp.GIMP/config/GIMP there was nothing, all the various folders were missing, i.e. there was no /3.0 folder and all the subfolders /brushes /filters /fonts /plug-ins etc.! So all the other various preference folders do NOT actually exist (!?); 
   
2. When I try to put a new brush in the brushes folder indicated by the programme (see above), it does not exist when I reopen Gimp. It should be noted that, since the folder did not exist (see point 3 above), I created the /3.0/brushes folder myself, but, as mentioned, even if I put new brushes in it, they are not recognised.
   
3. When I right-click on a layer, all the icons are missing from the list that appears. Have they perhaps been removed in the current version?
   

When working with Gimp's histograms, you always have the choice of whether you want to display the x-axis linearly or non-linearly. 

When working with python the function to get the histogram values has no paramter for the x-axis e.g.
t, mean, std_dev, median, pixels, counter, percentile = layer.histogram(Gimp.HistogramChannel.VALUE, 0.5, 0.6)
returns the values using the non-linear x-axis. 
In contrast the function to change the histogram e.g.
t = layer1.curves_spline(Gimp.HistogramChannel.VALUE, curve)
calculates the spline on the linear x-axis.
I found this out by comparing the values with the manually created values in Gimp.

I need a possibility to gett the correction by spline on the non-linear x-axis.

Is there a way to achieve this?
