Re: "Artistic" extensions to Gimp with (Wacom) drawing pad

[Markus Koskimies <mkoskim@xxxxxxxxx>]

I examined a little that "jamming" with mypaint, and it seems that in some circumstances, the mouse and tablet events are somehow discarded or something (they are not received to dialog message handler). Keyboard events are still received in msg handler, and e.g. X works correctly, and both xev and xidump receive events normally.

Since I have a feeling that it is somehow related to GTK, I think that my findings holds for gimp (and other gtk apps), too. I use tablet only for gimp and mypaint, and I haven't examined other gtk apps.

Oh, sorry, I didn't mean that you should not develop GIMP dynamics, just that you probably don't need to develop artistic brushes. But check out that MyPaint brush dynamics variables, that may give ideas for GIMP, too. Certainly, it would be just excellent, if GIMP and mypaint brushes would be interchangeable, maybe even a separate full featured brush editor for tuning them?

And yes, my aim is to (1) sketch pictures, then (2) paint, and then (3) make some finetunings, scaling and such. MyPaint fits for 2, GIMP for 3. GIMP is better for setting up the composition and sketching, but a little bit overweighted for that :) MyPaint lacks abilities for "scissoring" images, using grids/perspetive aids and such, which I find useful for sketching a drawing.

Maybe some point in future, there would be a bunch of programs, operating with same basic settings and file formats, so that I could easily use suitable drawing program for different purposes :)

Sliders and such tend to jam for me too. there seem to be some serious
issues in GTK with pointer handling since the clinet side windows were
put in.

MyPaint is  a painting application. Its meant for painting so it does
it well. MyPaint/GIMP have the same relation as Painter/Photoshop.

Image processing needs dynamics as much or even more than painting
approach. Theres a lot of brushwork in touching up a photo or creating
an image from other images. So in a way, without providing "artistic"
brushes, dynamics are very important to an image processor and very
much in scope.

If your aim is to paint then MyPaint suits your aims better.
