I've taken a load of photo's of old photo prints. They are not square on the photo's I have taken and some of the photos were not completely flat.

What I want to be able to do is select the four corners of the photo, square up the corners and crop to that size so end up with a nice square off straight photo.

I've tried searching but have been unable to figure this out. Any help would be appreciated.

Thanks

Hello, I'm having trouble trying to save a "project" (xcf file) on GIMP. I get the following error: "could not seek in xcf file invalid argument". From what I managed to find online it may be because the save file size is over 2GB. I wanted to know if there are any workarounds for this issue and also know why is the XCF so big when my original image is a jpg file of only 130mb and I have barely added any features in it, just about 4 paths. The bottom part of the gimp window is showing "filename.jpg (7.9GB)" and I have no idea where did that 7.9GB came from since, like I said, I've opened a 130mb jpg image. I used to have a ~7.5GB filme with the same name as this one (higher res version) but I've deleted it already and opened gimp by right clicking the new file (130mb) and selecting "open with GIMP".

Thanks in advance.

I need some advice a what drawing tablets are best compatible with the Gimp. Specific to Windows or Linux is fine. I am not looking for anything too fancy. $50 - $100 range.

BTW - 2.10.0-RC1 has got to be the most significant since 2.4 - Still want CMYK 

Is there any plug-in etc. for a virtual drafting compass that can be used in Gimp?
Thanks

So I've been working on this picture, but I've run into a roadblock.

   

I want to make this black bat red. So I use the fuzzy select tool ad highlight the bat. 

   

I select my desired shade of red and click on the bucket tool, all is going according to plan.

   

So I click on the bat with my bucket selected and...

   

What? This isn't just exclusive to red, with green it turns to a lighter grey and with yellow it turns white. What am I missing so that I can make the bat the color I've actually selected?

Hello
       Was hoping to post a Question about Gimp but before any of that I've got the same problem as gnuimpcub cannot see anything where the new avatar should be , oh and it's 90 x 90 at 7 KiB
  
What am I doing wrong that it's not working ?

Thanks in advance , Redraw .

I don't know how awkward of a question this is but here we go. So I am making art for a program called Hyperspin. The program naturally runs at a 4:3 ratio. I would like to upscale my art for it to HD standards. Unfortunately it is not as simple as clicking an option in the program. If you hit full screen it just stretches images to match the new ratio and everything looks stretched out. I would like to resize everything for 1080p and 4k as well but haven't the slightest of how to go about this to ensure that it displays correctly, compensating for the stretch the program is going to do and to make sure my image quality isn't trashed by the resizing. So far all other information I have been able to find info on the web for. This one I can't seem to find a damned thing for without being referred to flash. I wouldn't mind doing so but I would rather not pay a monthly subscription for a program (one time fee and I would be fine). Anyone have any information that could help me out here?

So I 'm a complete beginner. I just went through all the basic tutorials except the assets folder. I tried to go through the Luminosity mask tutorial, but I'm getting stuck at the "Create Even Darker Masks" section. I don't get results similar to what the tutorial has. When I subtract the lights channel (L) from the darks channel (D) I get something that looks less dark. I think I'm missing a few key steps that would probably be obvious to a more experienced user. I could provide my file for comparison if you want.

Thanks all,

Hello folks,

I use the shortcuts ALT GR-[ and ALT GR-] (WIN) for enlarging and reducing brushes of all kinds.

Unfortunately, the whole thing happens in 1 pixel steps. I would like to change this and increase it to 3 to maybe 5 pixels. Can I put this anywhere?

I searched in vain in the preferences.

Thank you

PS: I use Gimp 2.10 RC1 if this is important for the matter.
