Hello all,
Thanks for your responses,

You were right, the "perspective tool" I think about is more a "distortion tool".
Concerning the 2geom lib, I think this is the way to do it. It may be quite hard for students like us to start with such a project but I think it's feasible. Why don't give it a try?

Johan, if you want it and if the dev team accept it, you could be our "tutor" for this project.
Indeed the only things we need to get the project official in our school is a person in charge and a good requirements document.
For this one, the wiki is well done, updating it will be sufficient.

We would be very proud to contribute to such a tool.

By the way, when I talk about "Inkscape / GIMP raster graphics Editing Integration from GSoC 07" I mean a scenario like this one :
- right click on a graphic
- select "Edit in external editor"
- Gimp opens automatically itself on the graphic file
- Press the save button in Gimp
- Back to inkscape : the graphic is refreshed
The command line for opening a file could be customizable in user preferences (People might like to open Photoshop instead for example)
This project seams to be feasible too.

Thanks for your support.
