In fact, I also built glib from git, thus maybe GIO_EXTRA_MODULES was also
needed. Anyway, I used it and everything is OK now.

But you must install babl and gegl from git in order to build
gimp from git.

Just install them from git too, into the same prefix, using the
same environment.

[Gimp-developer] New gimp-gui-list mailing list.

2015-10-08 Thread Jehan Pagès 
Hello everyone,

The GIMP team has opened a new mailing list dedicated to discuss user
interaction in GIMP, in particular graphical interaction.

This is a place to discuss of the future of GIMP interface and any
decision should lead to properly designed specifications for further
implementation.
Anyone interested in participating should be aware of GIMP "product
vision", and works done in the previous years (cf.
http://gui.gimp.org/index.php/GIMP_UI_Redesign) since this is the
continuation of such works, and not a change of vision.

Of course, the same code of conduct (which you can read here:
http://www.gimp.org/mail_lists.html) applies there, as on all other
mailing lists managed by the GIMP project.

To subscribe: https://mail.gnome.org/mailman/listinfo/gimp-gui-list

Have fun!

Jehan

Re: [Gimp-developer] building GIMP from git

2015-10-08 Thread Sam Gleske 
It's likely that you're missing LD_LIBRARY_PATH when you're loading GIMP.
While you're starting GIMP that was compiled from Git it is loading GEGL
libraries from other sources.  You should do the following (assuming GIMP,
GEGL, and BABL were installed under /usr/local prefix by default):

LD_LIBRARY_PATH=/usr/local/lib gimp-2.9

GIMP will then look to /usr/local/lib for its GEGL and BABL libraries
instead of /usr/lib (which is where it is typically installed by a package
manager).

With everyone telling how they build GIMP I would like to add how to avoid 
setting the LD_LIBRARY_PATH: baking the path into the executable.

I am installing everything (babl, gegl and GIMP) to /opt/gimp-GIT/ (which 
belongs to my user so I don't need root to install). These are my calls to 
configure the three, afterwards a simple "make -j5 install" is enough.

babl:
LDFLAGS="-Wl,-rpath -Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" 
CXXFLAGS="$CFLAGS" ./autogen.sh --prefix=/opt/gimp-GIT/

gegl (disabling stuff just because I don't need it):
PKG_CONFIG_PATH="/opt/gimp-GIT/lib/pkgconfig" LDFLAGS="-Wl,-rpath -
Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" CXXFLAGS="$CFLAGS" 
./autogen.sh --prefix=/opt/gimp-GIT/ --disable-docs --without-libavformat --
without-vala

GIMP (with mypaint being installed in /opt/mypaint/):
PKG_CONFIG_PATH="/opt/gimp-GIT/lib/pkgconfig:/opt/mypaint/lib/pkgconfig" 
LDFLAGS="-Wl,-rpath -Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" 
CXXFLAGS="$CFLAGS" ./autogen.sh --prefix=/opt/gimp-GIT --enable-python

Each of them is one line.

Re: [Gimp-developer] Fade length setting for paint dynamics

2015-10-08 Thread Ofnuts 

On 08/10/15 14:05, Jon Tait wrote:
1. The "percent" setting is relative to maximal image dimension (ie. 
image width or height, whichever is larger).
Ref: 
https://git.gnome.org/browse/gimp/tree/app/paint/gimppaintoptions.c?h=gimp-2-8#n591
And as far as I can see it *does* work as intended - eg. Paintbrush 
Tool with Dynamics=Fade Tapering, Fade length=100% will fade in/out 
over a *stroke* length equal to the larger of image width and height. 
And pro rata for other values of "percent". [But note that it is the 
maximal *image* dimension, not *drawable* dimension.]


I tried that and it didn't seem to work.



2. No it cannot currently be set programmatically. The fade parameters 
are *dynamic options* (ie. specific to the fade dynamic), not common 
*paint options* (ie. applicable to all paint tools regardless of 
dynamics). And setting dynamic options is AFAIK not currently 
supported via PDB. IIRC this problem has been noted before but I 
cannot find anything on bugzilla about it now. Note this is a wider 
problem than just fade length, it requires a generalized method of 
getting/setting *all* dynamic options.




Dynamics take their other values from the general context For instance 
the varying "color" in the Dynamics uses the context gradient, the brush 
size is the context brush size, etc... And if I change a 
dynamics-related setting (fo instance, the "repeat") for one tool 
(brush), the value changes for other tools (airbrush, clone...).
