In pushing towards ivtools-1.1 (due in the fall, as usual), I'm looking at
wrapping up a full-featured implementation of the alpha-transparent,
anti-aliasing mechanisms people have come to expect in their
drawing editors. You really don't need the anti-aliasing until the
drawing gets rendered via ghostscript, but you want it, don't you.
My plans have been informally documented here:
http://advogato.org/person/sej/diary.html?start=139
But these are the goals:
- alpha-transparent rasters with EPS export/import
- user-selectable global anti-aliasing mechanism by
rendering to pixmap at 2x, and reducing on the fly
- polygon-clipped rasters with EPS export/import
This postpones things like PorterDuff alpha-compositing
(with an 8-bit key or mask) and Sketch-like blend-groups
(however you do those), but it augments the easy-to-use,
easy-to-understand GUI of idraw with modern-day tools.
