Hello everybody and happy new year

I am asking here: Cyan is integrated with Gimp.
I need to convert RGB to CMYK for printing.
I wanted to use Cyan or Krita, they seem equivalent.
I found something very odd to me, so after a lot of tests, imho the issue is that  
whatever the optional settings, with the exact same conversion to CMYK, tif and jpg :
a difference of about 95% exists between the jpg and tiff versions 
(using a very consistent application)

The two CMYK versions, tif or jpg, are not even similar obviously. Even visually.

Many other tests suggest that this cannot be caused just by jpg loss of quality.
I would use the tif format, but this strange total difference seems worrying to me.

No idea if somebody way more knowledgeable, can suggest something.
I emailed the developer of Littlecms, but I don't know if they will clarify.
Maybe somebody can just confirm that the tiff version should be correct enough?
Btw, the only format producing an output equivalent to tif, is Photoshop, psd format. 
Also, the result is the same with Krita or Cyan. I think they use Littlecms. 

Thanks for any help or suggestion and best
enri

I've been writing a python plugin for gimp, using RC2 installed with flatpak.  It's been a steep learning curve but i have it working.
I now want to take some of that code and put it in a standalone python app, since it doesn't actually need the gimp interface

My idea was to simply use the system python and import the necessary gi repository files - but they are already installed inside the flatpak

Is there a way to use the python version installed with gimp and flatpak from outside the flatpak sandbox?
Or should I copy the gi repository files into the system python directories, and if so where?

Many thanks

mijn laptop draait op MS Windows 11. hier heb ik GIMP 3 RC2 geïnstaleerd.
vorige versie was GIMP 2.10. daar had ik g'mic geïnstaleerd.
nu heb ik de nieuwe versie van G'mic (3.5.0) maar wanneer ik deze uitvoer komt deze niet zoals vorige versie te voorschijn onder filters in GIMP 3 RC2.

Hoe is dit probleem ontstaan?

So you can determine which assembly vote changed what.

(yes, some changes appear to be 200 years in the future, due to a typo, fix is in progress)

Hi All,

Is there an old photo restore plugin for Gimp 3.0?

I asked this guy for it:
     https://github.com/stongey/PhotoRestore/issues/2

But  I am not sure he has written it yet or ever will.

I have notice recently that these can be opened on Gimp. I have only tried it with 3RC1 so do not know if this was always a thing.
I assume once this file is worked on it will change into a bitmap/rastor image? Please set me straight.

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.
