Comment #75 on issue 2658 by [email protected]: wrong stem rendering
(inconsistent thickness)
http://code.google.com/p/lilypond/issues/detail?id=2658
Sigh. File size increase: the path for a rounded rectangle has
quartercircles at its corners. PDF can only represent Bezier splines in
paths. So converting PostScript to PDF will produce lots of splines in
order to have "correct" quartercircles.
The previous representation was one of stroking a rectangle with a circular
pen (which is representable in PDF) and filling it afterwards. But this
does not work well with the imaging model of Cairo, and it does not
rasterize fabulously well, either. I am slowly coming to the conviction
that we should produce different output for PostScript and PDF, that
neither should be converted into the other, and that we are likely best off
junking the use of Ghostscript for pretty much everything. Its imaging
models don't match the output devices we want to be working with. Possibly
excepting black&white printers _without_ an intermediate PDF stage. But
who works with actual PostScript files for print?
