[comp.windows.news] Adobe PostScript engine bug?

marshall@software.ORG (Eric Marshall) (04/21/88)

        Or is it just my bug? The following program, when
printed on two different PostScript printers incorporating Adobe's
PostScript engine (Apple LaserWriter and DataProducts Laser Printer),
gives me the same funny picture. The program is supposed to just
draw a U at a 60 degree angle, but it comes out with the U, but
also a little spike on the left vertical bar. Changing the rotation
angle from 60 to 61 or 59, does not produce the little spike.
Also, changing the numbers sometimes does not produce spike.
Any ideas? Thanks in advance.
