I want to change the exposure on like 20 layers all at once. I thought the "layer group" feature should be the thing to use, but when I group all these layers together, all "color" options are greyed out when I select the group. I'm still only able to affect one layer at a time.

Is there any other GIMP feature that will help me do this instead?

Problem: try to fill a selected rectangle with bucket, but selecting the bucket tool cancels the selection.

How to reproduce:
1. Create a new layer, fill it with white
2. Select a rectangular on it
3. Click on the bucket tool  ... Oops! Bang! 

The selection goes away. Nothing left for the bucket to fill. Would like to understand why this happens and how to make the selection stay long enough for the bucket to fill it?

Hi, 

I'm relatively new to GIMP and have just made my first image (an advert for an eSports match). However, when I go to export it, it adds a grey block into the middle of the image... I've linked a png version of the image exported image. 

There's nothing that shape on the xcf file and I can't work out why it's happening. When i reload that PNG into GIMP it actually shows the block as transparent. 

The xcf file can be found here.

I've got no real idea where to start! Any help would be welcome

Hi everyone, new to this forum and very new to GIMP too! 

I started using it to edit my product photos for my Etsy shop but am having trouble achieving a good, professional looking consistency between the pictures. I use my phone to take photos and use only natural light(I have an inkling this may be part of the problem as the lighting switches so much from moment to moment). I want my product photos lighting and colour balance etc to look consistent but it seems that no matter how much I play around with the controls(Colour- Levels, Colour- Colour Balance and cropping a segment of the target image and layering it over the other to try and get colours the same) but I cant get it close enough.

For example, I want this picture...



to have the same sort of lighting etc as this image...



Any help very much appreciated!

I have just put Ubuntu 20.04 on a new disk and installed version 2.10.24 of GIMP using the "Ubuntu Software" application.

My images are stored on a secondary internal hard drive that is automatically mounted on boot.

When trying to open a file, if I click on any folder on that mounted drive I get the following error:




I've set all of the permissions to "On" from the Ubuntu Software app and have manually set all directories in the path to rwx across the board.

What have I forgotten?

Thanks

PS - I had no issues with the same hardware and Ubuntu 18.04 (alas, I didn't make a note of the GIMP version)

I downloaded the current stable version this morning. I have a line drawing of a star.  The checkerboard pattern is outside  and inside of the star line drawing.  Is there a way to get rid of all the checkerboard both inside and outside the black line drawing?  Thanks in advance to all who answer.

I have a folder containing JPGs of page scans. Each page is "4-up," that is, has an image in each of the four quarters of the page. I'd like to automate a process of GIMP reading in each file in the folder, centering the image on an 8-1/2" x 11" canvas (in case the original scan wasn't exactly this size), then parting out each of the four quarters into separate files (ideally named as the original file, but with -1, -2, -3 and -4 as suffixes).

Given that I've never used scripting or other automation in GIMP, can anyone suggest the simplest route, that requires the least amount of education on my part?

Ok, it is a lot better then when i tried it years ago. But still missing in areas.

1 - File\open dialog box is bad. It should be like a file explorer so you can see your files both in list form and\or thumbnails (small,med.large). Just having a list is terrible if you have hundreds of pics in each folder. You should have thumbs so you can quickly scan for the picture you want to open. Who can remember what name or number goes with ea pict.

2 - Also File\Open, i want to have it always open to my picture dir\folder NOT recent. I can find no option to change this. Recent is nice to have but not as a default file open.

3  Toolbox is very limited. It should list ALL items in the drop down menus so to customize your toolbox how ever you want. Not just the few that are listed.

4 - Toolbox2, a second horz or vert toolbox for more customizing. More tools visible 1 click away. My preference is horzontal.
For some reason the menu\tools\toolbox sometimes list create new toolbox but nothing happens and nothing in the help about it.

5 - Fix mouse over on toolbox. If you have all group it works fine but it you have groups and single items mouse over locks up on the single item. You then have to click on a group item to get mouse over to work again. Mouse should not lockup just by scrolling over a single tool.

6 - Pet peeve - Default install should be to the program files directory not app\data folder. Just a nice extra feature when install is complete it should ask if you want to run\start gimp.

I know i am forgetting something but will find it more i get into gimp, maybe even more LOL.

Hi everyone, newbie here (old paint shop pro user from the jasc shareware days)

I installed gimp about 4-6 weeks ago to test it again (tired it many yrs ago)
Trying to set it up a way i like the look and feel and found 4 different black themes.
Found 1 i liked thought things were looking good. Then yesterday i tried adding some gimp and psp plugins and everytime it would crash. Even deleting the plugins i could not get gimp to restart start.
So early today i downloaded and installed ver. 20.10.24. Now none of the black themes work, all 4 are all white.
Anybody have any clue???  

Thanks - rider

HINT, gimp need to add a black theme
