This actually already exists in trunk with the GimpTagged interface. But
it's probably OK to keep it here as a task.

I would be willing to mentor this project.

 == On-canvas text editing ==

I would also mentor this one, but I can definitely not mentor two
projects.

  Properly map Gimp Widgets and objects to Python 

Instead of mapping GIMP widgets to Python directly, it would probably
make more sense to make sure that GIMP widgets are GtkBuildable. The
GtkBuildableIface interface contains method that are necessary to allow
GtkBuilder to construct an object from a GtkBuilder UI definition. This
would make it a lot easier to write GIMP plug-ins as developers would
have less hassle with UI code.

 == SVG brushes ==
 
  VBR brushes in GIMP - basic shapes like ellipses, rectangles and 
 rhombuses; with additional spikes - are scalable. In SVN trunk, all 
 brushes including the pixmap-based ones can at least be scaled down. 
 We do not yet have means for more advanced brushes (think about a 
 brush consisting of two disjoint circles) that can be scaled up in a 
 lossless way.
 
  Using SVG files as brushes could help to solve this.

I don't think that SVG brushes is enough for a GSoC project. Adding a
loader for SVG brushes can easily be done over a weeekend. What would
make this a lot more interesting is to add the infrastructure in the
paint core to actually make use of transformable brushes.

== Integration of GHNS for GIMP ==

 Though you can add more brushes, patterns, gradients can be added,
Most users, not even pros usually add them off the internet. This is
so as there is no architecture to quicky share/add from a centralized
repository. This seriously limits sharing of resources among the
users.

 GetHotNewStuff (GHNS) could probably help out here.

 Hi -

 here are the ideas listed again. I had trimmed down the previous list,
 as there are things that simply do not sound attractive enough for
 anyone to pick.

 Ideas for Gimp-python and the UF-Raw plug-in have been added.
 And we are still lacking mentors for pretty much everything else.  :-)

 Also, there is still a little time for adding some more ideas, or try
 to focus some more.

 == Tagging of GIMP resources ==

 Currently resources such as brushes, gradients etc are shown to the
 user in an unstructured way, only sorted alphabetically. This greatly
 limits the number of items a user can deal with.

 People love to make collections of things and think of them by names
 for these collections, like sprinf flower brushes or fancy fonts.
 However, one resource can belong to more than one set, and there can
 be sets which are determined by other means than the content, maybe
 even without the user having to do anything manually -
 think Favorites, Most recently used and Most frequently used.
 It has been suggested that this should not be a finite set of
 categories, bug rather done by assigning tags.

 The tasks in this project include:

  * adding a way for gimp resources to be tagged
  * decide which types of resources (i.e. which types of gimp objects)
 should be tagged
  * find a nice way for users to manage tags (add them, remove them)
  * present tags in the UI (i.e. how do you show them in the brush
 list, font list, ...?)
  * think about how tags can assigned to resources (or resources to
 tags)


 == On-canvas text editing ==

  Right now, the text tool opens a dialog window where the text has to
 be put, thereby creating a new text layer. Nearly every other option
 of the text tool - font, font size, color, line height, ... - is
 available in the text tool options dialog, so it would be nice to get
 rid of this dialog as well. There have been feature requests about
 being able to edit text directly on the image, like for example
 Inkscape does it.

 It may be that getting to the point where editing text on the image
 canvas is possible isn't that much of work, actually. But this is
 where the interesting challenges do begin: eventually, we do also
 want multiple styles in one text layer. This is not so straight
 forward anymore if your enter text in the image. Not present right
 now, so not having it isn't exactly a showstopper, but making it hard
 to ever get there is.

 And you will have to consider support for GTK+ input methods. They may
 be used to enter characters from languages (or, more precisely,
 scripts) beyond the simple Western scripts which define how our
 common keyboards are layed out. This is supported right now in any
 GTK+ text entry, not having it for on-canvas editing would be a
 regression.

 Tasks for this project include:

  * port the text core to PangoCairo
  * get on-convas text editing implemented
  * figure out if we do still need a text entry dialog (even Inkscape
 still has it in the properties of the text object)
  * make sure that GTK+ input methods work this this new approach
  * think about making it possible or not making it impossible to style
 the text while editing it this way


 == GIMP Python ==

 mentors: Yosh or João

 With version 2.4, python becomes the preferred method
 of scripting plug-ins for GIMP. Python is an universal multipurpose
 cross-platform
 language, adopted as scripting language by several applicatives, easy
 to understand,
 with a feature rich set of standard libraries.

 GIMP python scripting is possible since 1999, before version 1.2 and
 it allows
 access either to GIMP's procedural database and to internal image
 pixel data, just like
 plug-ins written in C.

 However there are points that can be greatly improved. Things that can
 be done for a
 Google Summer of Code project:

  Properly map Gimp

 I am posting the full set of ideas bellow and asking for commetns on

Sorry, the text you posted is so badly formatted that I am not willing
to read it. But nevertheless I would like to say that IMO we should try
to focus on GEGL and babl tasks for this year's SoC. That should bring
us closer to our goal of full GEGL integration in GIMP.
