Curious -- I have no trouble compiling that file. It's not finished, though. I want
the three buttons to provide a way to show Krita full-screen, full-screen with a
menu bar and normal, and I got kind of side-tracked with other issues. So if you
feel this is something to wet your feet with...

No, it's just me not paying attention. The problem is that qt designer 3.3 is already
part of SuSE 9.1, so it's what I'm using. I should hand-edit the .ui file to change 3.3
to 3.2, because that's all there's too, really.

The big issue at the moment is selections -- I'm working on that, though. Something
that will show you around in the code would be a bicubic scale method for kis_paint_device.
The scale routine now simply calls a generic transform, but that doesn't give very nice
results. If you're interested in print, you might feel like debugging the cmyk color strategy.
Alternatively, there's the option of working on the composite ops in composite.h. Something
that's quite separate and would be very nice is to implement the three pointer modes we need:
cross-hair, tool iconic and brush shape. That needs a bit of work on the config dialog,
some options in the tools, and finally the code to xor the brush shape in the view. We need a
way to define kernel ops on image data, too. To start with this you could create a convolution
tool.

And if all this doesn't appeal -- there's the TODO in the Krita root. It's quite up to date,
so feel free to pick an item.

Also -- make use of the archives for this mailing list. Between September 2003 and February I
asked Patrick Julien, who was the previous maintainer and architect of most of Krita's core,
a lot of questions which he patiently answered. And at http://koffice.kde.org/krita there's a
link to a short overview of Krita's architecture with reference to the actual source files.

Have fun hacking!
