I've downloaded GIMP 2.10.30 and there are three tone-mapping algorithms, the latest is of year 2006 by Mantiuk. Which are some modern and better algorithms and how to add them? I have a jpg image that needs tone mapping.

Please, reply in simple words, because I don't even know what tone mapping is. I just click on tools until picture is pretty.

Mantiuk gives a nice result, but the picture looks dirty, and some red, yellow and blue pixels show up. Any newer free online algorithms?

I'm using Gimp 2.10.30 on a Windows 10 system and having trouble opening images.  They open at seemingly random scales, sometimes tiny on screen and sometimes massively zoomed in.  I can immediately resize them to fill the screen with ctrl+shift+j but still it's a bit annoying and a problem I never had with any previous Gimp version.

Thanks in advance if anyone has a solution.

I am working on scanning some historical texts, in Chinese - unfortunately the pages are somewhat yellowed and blotched, like the one attached. Is there a easy way to make the background paler - or even completely white - while preserving or darkening the ? I'm preparing the photo for OCR; so far I have only managed to digitalize a minor part of the text.

   

The last gimp build I had 2.10.22 had a Raw editing Program already in it. (I don't remember installing one)
I am now using 2.10.30 and it doesn't have any but is telling me I can install RawTherapee or Darktable to open Raws
I have downloaded them...where do I put them?

Hi

[I am using GIMP 2.10 on Windows 10]

I have used Warp successfully on many occasions but right now all I am getting is a warning message 
'GIMP warning no stroke events selected'

what does it mean. how do I use warp again ?

thanks,
Pete

Windows users often seem to re-install Gimp for whatever-reasons  often with no result because the user profile remains.
However, sometimes it is necessary, for example, installing Gimp in a different location.
This a pdf walk-through of the stages using the Gimp installer with the Customize option

The pdf , "on the drawing board" a while, but finally got it down to a reasonable size.
Edit: Spot the mistake, fixed now, duplicated graphic, hate these pdfs, sometimes have mind of their own.

I want to make a PDF with pages of different sizes and I add them as layers to the first page but Gimp crops the ones which are bigger than the first page. How can I do it then?

You know when you open Gimp and it has a default canvas? This:

How do you get it to open that default canvas when you click File>new? Because it asks me to define all these properties when I click new, like this:

But I just want that canvas that you get by default when you open the program. How do I do that? Thanks.

Hello,

I found there is a module for GIMP to read .djvu files on https://github.com/cosmiclattes/gimpDjvu

That is from 8 years ago, so I assume it must  be incorporated into the main program by now. Actually, when installing GIMP on my Windows machine, it declares itself as the default reader for djvu-files. And yet, it doesn't work. I assume because the proper open library, referenced in the above github page, is not installed for GIMP. How do I do that?

I'm running  GIMP 2.10.8 on Windows 10 Pro.

The error message is:

If I use the eyedropper in Levels to set the gray balance, is there a way to apply this settings to other photos?
