[Gegl-developer] gegl-qt 0.0.7 released - 0.1.0 preview
gegl-qt is an integration library for using GEGL in Qt based applications. gegl-qt provides a NodeView widget, showing the output of a node in a GEGL graph. Variants exist for QWidget, QGraphicsView and QML based user interfaces. The widget supports translation and scaling, along with autoscaling and autocentering. Python bindings for use with PySide are also provided. This release is a preview of the first stable release 0.1.0. Please help test. Tarball: http://www.jonnor.com/files/gegl-qt-0.0.7.tar.bz2 Md5sum: fbb0692af354d404615980a68c8a88f4 Git tag: http://git.gnome.org/browse/gegl-qt/tag/?id=0.0.7 Minor things like default arguments might still change, but unless bugs are found the API is final. What is missing now is mainly documentation (API reference, introduction). For now see the examples found in the examples/ directory for usage. gegl-qt is package for Arch Linux, and can be found here: https://aur.archlinux.org/packages.php?ID=52759 -- Jon Nordby - www.jonnor.com ___ Gegl-developer mailing list Gegl-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer

hello,
I am having trouble to save gegl operations to repeat them later. I
think, that gegl_node_to_xml is the operation I am looking for, but this
can be wrong.
I wrote this small program:
#include stdio.h
#include gegl.h
gint
main (gint argc,
gchar **argv)
{
GeglNode *gegl, *gn_load, *gn_save, *gn_op;
gchar* xmltext;
g_thread_init (NULL);
gegl_init (argc, argv);
gegl = gegl_node_new ();
gn_load = gegl_node_new_child(gegl, operation, gegl:load,
path, bsp-900x600.jpg, NULL);
gn_save = gegl_node_new_child(gegl, operation, gegl:jpg-save,
path, out.jpg, NULL);
gn_op = gegl_node_new_child(gegl, operation,
gegl:unsharp-mask, std-dev, 1.2, scale, 8.0, NULL);
gegl_node_link_many (gn_load, gn_op, gn_save, NULL);
gegl_node_process (gn_save);
gegl_node_to_xml(gegl, xmltext);
printf(xmltext: %s\n, xmltext);
You probably want to do xmltext = gegl_node_to_xml(gegl, pwd); or
similar. Where pwd is the current working directory. See the
documentation at http://gegl.org/api.html#gegl_node_to_xml
when I change it this way:
xmltext = gegl_node_to_xml(gegl, /home/joerg/src/geglex);
printf(xmltext: %s\n, xmltext);
then I get only an empty node as output:
xmltext: ?xml version='1.0' encoding='UTF-8'?
gegl
/gegl
is this the expected output? I thought, that the node named gegl would
contain the other nodes (gn_load, gn_op and gn_save) but I am new to
gegl and may be wrong. I tried to print the complete transformation to xml.
What would give the entire tree of the operations?
I don't think you read the documentation I linked you ;)
To export a gegl graph, connect the internal output node to an output
proxy (see gegl_node_get_output_proxy.) and use the proxy node as the
basis for the serialization.

gegl_exit ();

libpcre.so.3 = /lib/i386-linux-gnu/libpcre.so.3 (0xb738)
And I hoped, that xmltext would be string, containing a xml tree for
this little gegl operation. unfortunally all I got where a handful of
binary bytes - not the xml text (somthing like gegl/gegl) I
hoped for.
Any hints for me?
thanks in advance

The version of Qt installed is 3.3, I need the 4.x series. Should have been more specific about that. It probably has a package name like qt4 or libqt4, a lot of distros have qt meaning 3.x series still (even though 3.x is not being worked on after 4.0 came out in 2005 or so).

[Gegl-developer] GEGL + QT, another proposal
After some hacking this weekend, we now have a minimally useful gegl-qt library: https://github.com/jonnor/gegl-qt Currently it a set of a basic view widgets* showing the output of a GeglNode. A bit more info can be found in the README.txt file, and examples showing the usage can be found in the examples/ directory. Testing, usage and contributions welcomed! Unless there are any objections I propose to do the same as with gegl-gtk: Put on git.gnome.org, create a gegl-qt component in bugzilla and add to Jenkins. Martin, this thing uses qmake. For adding to Jenkins is there anything special I should do? Create a configure script (wrapping qmake), and add a distcheck target? * One for each of the widget paradigms in Qt4 (QWidget, QGraphicsView and Qt Quick). -- Jon Nordby - www.jonnor.com ___ Gegl-developer mailing list Gegl-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer

I think the gnome git repository is the most natural place to stick this convenience library since it is based on GEGL and all the other GEGL pieces, including a gegl-clutter library which I added there today are hosted. So unless there are any other objections I do not see why not. The purpose of the library is to facilitate the use of GNOME technology (GEGL), so I personally do not see why it should be a problem. The relevant stated pre-requisite for things hosted on git.gnome.org is It must use GTK+/GNOME technologies.[1], which it definitely fulfills. 1. https://live.gnome.org/ProjectPrerequisites -- Jon Nordby - www.jonnor.com ___ Gegl-developer mailing list Gegl-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer

Just provide the set of commands used to build gegl-qt after a new git checkout and I'll take care of the rest. qmake -r make If installing is wanted, qmake -r GEGLQT_INSTALL_PREFIX=/custom/prefix (default prefix is /usr) and make install can be used. In the qmake world, INSTALL_ROOT is equivalent to DESTDIR, if there is want for such. The buildsystem uses pkg-config for finding GEGL, of course. Note: On Fedora and similar, qmake might be qmake-qt4. If you want (I encourage you to), create an account on Jenkins so that I can give you admin privileges so you can configure jobs. Done.

The .gir and .typelib will only be built if you have the required libraries for introspection available at build time. Using the .gir file for bindings has very little to do with Gegl.
