On my Windows 7 machine (all updates), with IDL 8.2.3, I run this
command:
IDL> cgplot, cgdemodata(1), Title='This is a Long Title', $
XTitle='This is Another LONG Title', $
YTitle='And Still Another Tiitle', $
Font=0, Output='test_hardware.ps'
I'm viewing the PostScript files in GSView 5.0 at a very high
magnification (at least 300 percent).
If I set FONT=0, I see no evidence of lines. If I set FONT=1 (with a
Times True-Type font selected), I see evidence of lines in the Plot
titles, including the X and Y titles, but not on the number annotations
for the axes.
If I set FONT=0, and turn anti-aliasing on in the viewer, the text is
smooth. If I turn it off, the text is jagged about the boundaries, as I
expect.
If I set FONT=1, then the output (although it has lines from the
polygons that made up the title fonts), shows no effect with anti-
aliasing on or off. Also, exactly what I would expect.
The lines (or not) from the PostScript file is carried over to the PDF
file when I create that from the PostScript file.
If I set FONT=1 and render in 24-bit color in the PostScript device,
there is no difference from doing this in 8-bit color.
If I set FONT=1, LANGUAGE_LEVEL=2, DECOMPOSED=[0 or 1], there is no
difference in output.
Any clues there? :-)
Cheers,
David
