I rotated an image by mistake a few degrees. Then I did some coloring etc on it that I dont want to undo. Now I want to rotate it back so that it is aligned horizontal again. How? I tried image>transform>rotate but couldnt do it. All I want to do is to bring it back to its original horizontal alignment

I am trying to do 3 simple things, but I cannot figure out how to accomplish this. So, here goes.

1) I want to take a .TGA file, rotate the image 90 degrees, then save it as a .TGA file under a new filename. As far as I know, that is the only format read by the game I am fiddling with.

2) I want to take a .TGA file, change the color(s) of the image, then save it as a .TGA file under a new filename.

3) I want to take a .TGA file and simply add a border to the image, which is square.

Please let me know in simple terms how to accomplish these tasks. I am new to Gimp and have never been good with image manipulation. Scripting/Programming, yes. But I', not what you would say the artistic type.

Thanx to any and all help.

Hi all,

I need some help with a colour matching on a piece of work I am currently doing.

I have attached the first image where no colour matching has been applied to the subject. I have attached a second image where colour matching is applied.

I am experimenting with levels, colour balance, brightness, contrast, saturation etc, but I can't quite get it how I would like. For example the background is reddish, so I am applying red using colour balance to the woman, but she might look too red. However, if she doesn't have a reddish tint, then the subject woman also doesn't match.

Can I get someone's advice on this please?

Thanks in advance.

EDIT: I have also applied a slight linear motion blur to the second image to help blend the woman in more.

I would like to make a image of a US license plate from individual p.n.g letter images I have purchased from Etsy. 

If I make a template the size of a US plate (it needs to have rounded corners) and open all the letter image layers, can i just drag them into the correct order on my template ?

My PC currently runs Windows 11 Home. 

What I would like to know is how do I change the Icon picture in file explorer to show the actual picture contained in the file instead of the GIMP logo ?

New to gimp and working in to it bit by bit and getting dead ends partly I think doing things in the wrong order.
In the attached jpg I need to
1. select the round plate, rotate it slightly, and separate it from the background
2.fill the background with a solid colour
3. select a square around the plate slightly bigger so it sits against the coloured background.
4. set it up to print 8x8” at good resolution.
I suspect I am making a fairly simple task more difficult by doing steps in the wrong sequence.
Appreciate any help.  
eg get crawling ants around both the plate and background and can't do anything with it

Hi all,
I am new to using GIMP, and could use your advice/input. I have several solar eclipse photos from the April 2024 eclipse, and I would like to arrange them in a sequence.  I'd like my total eclipse photo to be in the center of the sequence, with the stages leading up to it, and after it on either side.

I am not very technically savvy with computer software in general, and have limited free time to learn GIMP and all its functions. I found quite a few detailed/complex tutorials that show how to create an eclipse sequence in photoshop, but I couldn't find a good basic one for GIMP, so I would appreciate any assistance. 

I assume I will need to load all my photos in layers, then somehow put all the images on top of a black background. Then I'll need to adjust their size and move them into the correct positions. Can someone suggest a very simple way to create this type of image? As I am not very familiar with the tools in GIMP (or even how to create a black background), if you can be very specific with a step-by-step process that would be greatly appreciated!  Note - I have version 2.10.32 revision 1.

Any assistance will be greatly appreciated!

See the attached image. I am attempting to export an image. I can't find a necessary button to complete the export.

What am I missing?

The conventional copy command obtained by the free select tool makes a copy of the free select tool outline and what it encloses. Is it possible to copy the outline free select tool path only, move it to a new area, have the free select tool enclose some new material, and move the free select tool now with the new material back to sit over the original, exactly matching the original free select outline?

Maybe it already exists, but I don't know it's name!

Thanks in advance.

Is it possible to achieve a long shadow effect in GIMP where the long shadow spreads out, as if coming from a central point?  Here's an approximate example of what I mean, which I did by separating the text into 3 parts and applying separate long shadows to each:

   

It should give the general idea but it's only an approximation; each letter should have a different shadow angle pointing out from the letter towards an imaginary circle behind it.  I can't see any way to do this.

Thinking about it, it'd make sense for the long shadow filter to have a "spread" option, where 0 does the current behaviour, negative would modify the angle so the shadow converged, and positive would modify it so the shadow diverged.
