… and gimp_brush_get_mask(). gimp_brush_get_pixels() was a bit crappy, returning raw data with only dimensions and bpp to go with (no color model/space, no bit depth…). So the assumption is that we work with 8-bit per channel data, possibly with alpha depending of number of channels as deduced from bpp, and very likely in sRGB color space. It might be globally ok with many of the brush formats (and historical brushes) but won't fare well as we improve brush capabilities. - gimp_brush_get_pixels() is in fact made private. - The 2 new functions are using this old PDB call _gimp_brush_get_pixels() to construct buffers. This has some limitations, in particular that it returns only 8-bit per channel sRGB data, but at least the signature won't change when we will improve things in the future (so if some day, we pass fancy brushes in high-bit depth, the method will stay the same). - This new implementation also allows scaling down the brush (keeping aspect ratio) which is useful when you need to fit a brush preview into a drawing widget. - Current implementation stores the buffers at native size in the libgimp's GimpBrush object, hence save re-querying the core every time you need an update. This can be improved as current implementation also means that you don't get updates if the brush changed. This should handle most common use cases for now, though. - Also with this change, I move GimpBrush class implementation into its own dedicated file. |

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 3.0. 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.
The latest version of GIMP can be found at:
https://www.gimp.org/downloads/
2. Contributing
===============
GIMP source code can be found at:
https://gitlab.gnome.org/GNOME/gimp/
Resources for contributors:
https://developer.gimp.org/
In particular, you may want to look in the "Core Development" section. Some
articles of particular interest for newcomers could be:
* Setting up your developer environment: https://developer.gimp.org/core/setup/
* GIMP Coding Style: https://developer.gimp.org/core/coding_style/
* Submit your first patch: https://developer.gimp.org/core/submit-patch/
3. Discussion Channels
======================
We have several discussion channels dedicated to GIMP user and
development discussion. There is more info at:
https://www.gimp.org/discuss.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.
Other discussion channels can be listed on this page when they are
moderated by a team member, such as forums.
Finally, for the real junkies, there are IRC channels 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/shortcutsrc`.
Have fun,
