Libre Graphics Meeting 2007 : Day 2

At LGM, even if it’s a not a big conference, at some point, you always need to split yourself in two or three.

Designer using Open Source software

The second day started by a talk by two designers coming from Belgium who made the choice to start a design agency which would only free software. Those guys seems to live on a different planet (well maybe there is three planets, one for designer, one for geeks and one for normal people), they show us some of their creation, I was a bit sleepy (and considering the number of people in the room, I guess nearly everybody else was sleeping elsewhere 😉 ), but what stroke me most is that apparently, they have some “creative” session where they try various things, even reverse engineering coca.

Then I meet up with Boudewijn to make the final preparation for our talk.

Inkscape + blender + inkscape + gimp + scribus

Then I went to a talk where CĂ©dric Gemy did a presentation where he shows how to use various open source software, he first used inkscape to prepare a spline that he imported in blender to create a 3D Greek temple, then he used inskape to create a mask for the gimp, and he finished in scribus for creating a leaflet.

Hour of fame of Krita

Then after lunch, it was the presentation of Krita. I am grateful that Boudewijn did most of the talking :) I am not used to do presentation in front of that many people especially in English. But I do think that it want very well, people seemed interested and we got interesting questions.


Right after the Krita talk, I did a presentation about what is OpenRaster (a file format for exchanging multi-layer raster images, I would be delighted to paste the link to the create wiki where the project live, but most of freedesktop is dead currently). My talk got a little bit hijacked by a discussion of whether OpenRaster should or should not support CMYK and full color management.

But I got interesting ideas, notably one from Pablo d’Angelo (of hugin fame) who wondered if OpenRaster could be use as an output from hugin, where hugin would save layers and their transformation, and then you can load the file in Krita or the Gimp to fine tune. And the answer is of course yes.

The last question was an offer by Liam Quin (XML activity leader at w3c) to help me improve the XML schema of OpenRaster, and it is really the kind of contribution I expected to get from this conference.

Then I missed two talks I wanted to assist, but obviously I had to miss one as they were happening at the same time. But, in fact, I missed two to have a private presentation of the node editor in blender which is very interesting because it is something I want to experiment with in Krita.

The work flow for creating panorama by a photograph

Yuval Levy, a photograph who do a lot of panorama creation, still a photoshop user but we talk a little bit how he works and how Krita could help him in his work, especially on retouching High-Dynamic Range images.

Then I went to diner with a bunch of people, including Pablo d’Angelo with who I talk a little bit about panorama creation tools, and what Krita could use from Hugin. And one of the most interesting things will be the interest point and matching, and he cleared my worries about it, as I was concerned that they would use something patent encumbered (like SIFT), but apparently they wont, so for my panorama tool I will wait a little bit and see what they can and will deliver during the Google Summer of Code.
