Upon further thought: traditional engraving is made by a combination of real engraving/cutting and stamping in a metal plate. One would think that whether a point on a metal plate is depressed in a stamping process, depends on the distance to the the stamp. That would mean that the shape of the depression is the Minkowski sum of a small circle (of radius blot_diameter) and the outline of the stamp. In other words: rounded outside angles, sharp inside angles. For cutting, one could vary the pressure on the cutting tool to produce lines that are thinner than blot_diameter; also it should be possible to produce sharp outside corners for symbols that are cut (bar lines, slurs, staff lines, beams). Anyway, this is all theoretical muttering: I'll take out my magnifying glass tonight to have a look. -- Han-Wen Nienhuys | [EMAIL PROTECTED] | http://www.cs.uu.nl/~hanwen/ _______________________________________________ Lilypond-devel mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-devel
