The GNU Image Manipulation Program

Our main issue is that GIMP does not accept indexed images with linear backend. MR !460 was an attempt to fix this, but some weird pixel data conversions were happening so the result was very wrong. We could try to investigate this and add support for linear RGB palette colors, but it's unclear how necessary it is (i.e. is there any indexed image format for which we'd want this? PNG is not one such format as will be explained below), especially that palette are u8 only right now and linear RGB u8 is not the best idea anyway. In cases reported in #6886 though, our code would say the input is linear mostly because it had a 1.0 gAMA chunk (or we could have a case with a linear profile too). But then we don't need to set such data as being in linear RGB. Just set it as non-linear RGB (R'G'B') with the associated linear profile and that's it. Setting a linear backend to an imported PNG would only be useful if PNG had some flag explicitly asking for this, bypassing any profile TRC. But as far as I can see in its spec, there is no such thing. |

GNU Image Manipulation Program
2.99 Development Branch
------------------------------
This is an unstable development release, an intermediate state on the
way to the next stable release: GIMP 3. GIMP 2.99 may or may not do what
you expect. Save your work early and often. If you want a stable
version, please use GIMP 2.10 instead.
If you think you found a bug in this version, please make sure that it
hasn't been reported earlier and that it is not just new stuff that is
still being worked on and obviously not quite finished yet.
If you want to hack on GIMP, please read the file devel-docs/README.md.
For detailed installation instructions, see the file INSTALL.
1. Web Resources
================
GIMP's home page is at:
https://www.gimp.org/
Please be sure to visit this site for information, documentation,
tutorials, news, etc. All things GIMP-ish are available from there.
There you can get the latest versions of plug-ins, using a convenient
forms-based interface.
The latest version of GIMP can be found at:
https://www.gimp.org/downloads/
2. Mailing Lists
================
We have several mailing lists dedicated to GIMP user and development
discussion. There is more info at
https://www.gimp.org/mail_lists.html
Links to several archives of the mailing lists are included in that page.
Gimp-user-list is a mailing list dedicated to user problems, hints and
tips, discussion of cool effects, etc. Gimp-developer-list is oriented
to GIMP core and plug-in developers. Gimp-gui-list is for discussing
about GIMP interface to improve user experience. Most people will only
want to be subscribed to gimp-user-list. If you want to help develop
GIMP, the gimp-developer mailing list is a good starting point; if you
want to help with GUI design, the gimp-gui list is where you want to
subscribe.
3. IRC
======
And finally, for the real junkies, there is an IRC channel devoted to
GIMP. On GIMPNet (a private free software oriented network) there is
#gimp. Many of the developers hang out there. Some of the GIMPNet
servers are:
irc.gimp.org:6667
irc.us.gimp.org:6667
irc.eu.gimp.org:6667
4. Customizing
==============
The look of GIMP's interface can be customized like any other GTK+ app
by editing files in `${XDG_CONFIG_HOME}/gtk-3.0/` (settings.ini and
gtk.css in particular) or by using "themes" (ready-made customizations).
Additionally, GIMP reads `${XDG_CONFIG_HOME}/GIMP/2.99/gimp.css` so you
can have settings that only apply to GIMP.
You can also manually change the keybindings to any of your choice by
editing: `${XDG_CONFIG_HOME}/GIMP/2.99/menurc`.
Have fun,
