I was playing with the Foreground Select tool some - but by the time I go through the process, then cleaning up the edges of the result it seems it would as fast or faster just to make careful use of the Free Select tool, with more precise control over fine details that Foreground Select will miss. 

Thoughts, experiences, tips/tricks?

Somehow I still do not understand how colors are processed inside GIMP. Let me explain my question on one example.

I run into 'easy' task to identify color in TIFF file. Each application I used shows different values. To identify what is going on I made simple test scenario. In Corel Draw created simple image with 2 colors (CMYK: 85/30/0/100, Pantone 186C). Exported this image to TIFF and opened it in:

GIMP - 0/0/0/100 and 0/100/88/11 respectively.
CorelPhotoPaint - 85/30/0/100 and 2/100/88/9 respectively.

I have read (here) about checking color profile, and there is set relative colorimetry, CMYK profile: None.

My question is: What colors are inside the TIFF? How should I understand the different values in different programs? For now please ignore different 'render' on the same screen, which initially triggered my curiosity, but I understand this is related to CMYK - RGB conversion where much more elements are included and more or less no standard exists, but was thinking that value inside TIFF is the same regardless of used program. Or not?

GIMP is version 2.10.24

I added pictures to google drive, there are 3 pictures showing eyepicker tool and corresponding colors (visual representation of the above text).

Thank you for explanation

Bonjour,
J'avais un souci avec Gimp 2.10.30 et les outils, c'est dire que quoique je fasse un outil restait constamment en plce, même en faisant "sélection aucune", impossible de m'en débarrasser.
J'ai donc désinstallé Gimp puis vérifier que toutes les traces étaient bien supprimées de l'ordi.
J'ai réinstallé Gimp 2.10.30 et surprise l'outil en question est toujours en place .
Avez-vous une idée et une aide pour m'aider SVP.
Cordialement.

What I want to do is copy images off a page, paste them into the same position onto a transparent layer, make the original page all white, then merge the layers as a quick and easy way to fix the color of the borders around images as part of a book restoration project - i.e. get rid of acid yellowing, etc. 

Here's my envisioned workflow -

- Outline image using rectangle select
- copy image
- move image to transparent layer and align it with original base layer
- convert entire original base layer to absolute white with flood fill
- merge layers

This is simple to do in PaintShop Pro - just change the layer you're working on by clicking on it, but layers apparently don't work the same way in GIMP. 

All assistance appreciated.

I just had to delete GIMP off my computer recently and right now I'm trying to reinstall the program. However, I keep getting an error because the installer is still linked to my old PC profile. I used it to first download GIMP years ago and since then I moved on to a new one and deleted the PC user off my computer. My problem is that even though I am using the current PC profile, the installer's destination is still mapped to a folder in my old one

"C:\Users\Old Username\App Data\Local\Programs\GIMP 2"

The installer is linked to a folder on a profile that doesn't exist anymore and it doesn't let me change it. As a result, I am unable to get GIMP back on my PC. I even tried going into my hidden folders and in Appdata in my current profile and tried reinstalling. The installer still does the same thing. Is there anything I can do to fix this issue.

new here..and am having fun with GIMP

i created a logo for myself and i am trying to figure out how to copy and paste it as a whole

on top of a jpeg i want to use for the background...without doing it layer by layer

is this possible?

Thanks in advance for any help

Hello,
I would like to know if there was an equivalent of "Dynamic object" of Photoshop on GIMP?
Thank you

Sorry if this is not in the right category.

Something's happened and now, whenever I select a layer that is NOT the size of the canvas, GIMP keeps selecting the entire canvas border...thus I can't align anything. What's happened?

Hi all,
i world like to 'cut', i.e. put to 0 some values above a treshold value.

Something like : if pixel value > 130 -> 0


The idea is to make some astronomical masks to remove noise. (erase signa, then substract noise)

How do I do this ? From scripts ?

Hi, I could use some help with dealing with "Expand from center" shortcut. Is there any way to remove this shortcut completely or god-willing completely disable that option? It's making GIMP practically unusable for me.

If you're holding left mouse button clicked, and press ctrl, if will auto enable. This is exceptionally frustrating as I use GIMP to create sprites so a lot of what I do is copy/paste little bits here and here, so I'm constantly selecting parts of an image by dragging the mouse and then clicking ctrl+x/c/v, which mean I auto enable it about 5 times a minute when I'm editing because those actions and the shortcut overlap 100%. It's gotten to the point where I want to downgrade to a much earlier version of GIMP as just about every time I want to select something to copy, I have to toggle "Expand from center" off, which keeps toggling itself on.

Please help. I'm on 2.10.30
