Some of my photographs have a chromatic aboration problem where some colours are out of sync with others. The problem colour appears to be green but it might be more tricky than that. Assuming it is green..

I thought it might be possible to decompose the problem image into colour layers in GIMP, move the pixels of one layer over slightly, and recombine the layers. I don't know exactly which colour is out of sync or how much to move them so it is an experiment.

For the first attempt I decompiled the original image into RGB layers, which produces three greyscale layers. 

Unfortunately the greys do not help me to see how much one colour is out of sync with the others, so I converted each layer to RGB and colourised them as the colour they are supposed to represent (red = hue 0, green = hue 120, blue = hue 240). I now have three distinct coloured layers that I can combine in various ways. I also created a solid white background layer.

However, I cannot find how to merge these layers to reproduce the original pre-decomposed image. Which transparency and layer modes should merge the red/green/blue layers to re-create the original image?

Hi there,

I'm a new user of GIMP, I want to import a bunch of SVG files (made with Inkscape) and convert them to jpeg files but when I open them any text that I have put on a path is missing for some reason!

Does anyone know how to fix this?

Cheers,
MEGA.

I installed GIMP 2.10.22 on Windows 10, choosing Swedish as language. After searching for tutorials I realised there was very little in Swedish. I had also changed things around and wanted a new fresh standard installation that would look like in the tutorials.

I uninstalled GIMP and installed it again, this time choosing English. To my surprise I got a Swedish version again, and the changes I had made were still there. I uninstalled again and this time searched for and removed all files containing "GIMP". Again, the new installation was in Swedish and my changes were still there.

How do I uninstall GIMP completely so that I can have a fresh new installation in English with the default layout?

Hi,
I need to scan a massive load of textbooks, and am trying to figure out the best way to do it.

I have made some test scans to JPEG, 300dpi, Colour. Which look kind of OK, pixilated obviously when zoomed in.

But I imported those same JPEGs to GIMP, and exported as a PDF, and it made them look a load better, smoother.

The 4 JPEGS are 1.95 MB together

But the PDF from GIMP is 13.2 MB

I gather this might have something to do with GIMP converting the JPEGs into Bitmap (is it?).

I just tried scanning one of the pages at 300 dpi BMP and it looks all pixilated like the JPEG's do.

I want the nice smooth PDF but without the much bigger file size. Is that possible?...

Cheers

Hi, Im new to gimp and have been learning it. I was cropping out a plane for a photo and i used the path tool. After I pressed enter and inverted the image and removed the background, I noticed this line and it never disappears. How can i remove it?

I'm using Gimp 2.8.22. I just brought it up, and the pattern box has vanished from the layer box where it has always previously existed. I haven't done any updates to my computer or any part thereof. I tried looking this up, and found descriptions of drag bars and drag handles that don't seem to exist no matter how much I hover and click and try to drag. Could someone please tell me how to get the pattern box back where it belongs? And maybe how to keep it there? Thanks! :-)

A maze, amazing I would say. Need one for a game? Generate one with a circular, rectangular, triangular or hexagonal shape. Also one have a choice out of different cells depending on the shape of the maze. Export as svg, png or pdf is possible. Import in gimp as paths and let your imagination go.. :

Hi all, 

I use GIMP to create YouTube thumbnails and have recently noticed a problem with the UI - it seems like it's mis-aligned with the mouse on my Mac? 

I use the software on MacOS 11.2.1 and it's only been like this for the last couple of weeks, although it was around a month since I last used it. 

Not only am I unable to align buttons on the interface with my mouse, when I open an image file, the application locks-up and although the menu bar responds, I cannot do anything with it. 

Has anyone else experienced this behaviour? I can't decide if it's been caused by a software update for MacOS or something else.. I have uninstalled, re-installed and updated to v 2.10.22 (rev 3) - nothing has resolved the problem. 

Can anyone help? The application is currently totally unusable and I can't publish anymore content until I can get around this!

Hi !
New on this forum and came for this trouble, I didn't found any relative threat. But ! I have this probleme on every machines, and with another same tablet.

the problem :

when using the pen, gimp switch randomly to corepen (normal mouse) tool.
sometime it keeps it until I go left, upon tools selection icons, sometimes it switches very quickly between pen/mouse tools.

tried :

• I already tryed to disconnect mouse, suspecting slow moves could have caused switching the tool for a correct reason.
  
• finger touch off
  

• Wacom pen&touch (2 differents)
  
• problem occurs on multiple computers
  
• W10
  
• The Gimp 2.10.22
  
• logitech mouse (if any know driver problem with)
  

Windows 10 Pro 20H2 build 19042.804 64 bit, 8 core Xeon, 32 GB RAM.  GIMP 2.10.22   GIMP has been working flawlessly for weeks - the only thing I did yesterday was to use the portable version of MOUSECONTROLLER to make repetitive editing easier.  But MC has to be manually started and I'm not doing that.  Unable to open a file - just crashes out with  dump file.

1) over install - N/C
2) uninstall thru control panel, reboot, reinstall as administrator so all users work - N/C
3) uninstall thru control panel, no GIMP folder in program files,  if search with hidden files on find lots in C:\Users\Me\AppData\Roaming\GIMP\2.10 - so I'm posting before I just start mass deletes - has 66 files totaling about 475K.  Haven't had to resort to this for a long time.  Dump file available.

Next - this?  Just delete every piece of GIMP I can find on the "C" drive.  Note that I keep all my files on other logical/physical drives so my "C" is only about 70GB of data.
