I don't know anything about how thickness keywords
translate into points, but I do know that doing things
by hand is a bit passe in the computer world. :-)

A little bit of foresight goes a long way when writing
IDL programs. For example, if you know you have a graphics
display program that you are going to want to make a
PostScript file of (and aren't *all* of them this way?),
then something like this works well:

PRO NicePlot, data

IF !D.Name EQ 'PS' OR !D.Name EQ 'PRINTER' THEN BEGIN
psthick = 3
thick = !P.Thick
xthick = !X.Thick
ythick = !Y.Thick
zthick = !Z.Thick
font = !P.Font
!P.Thick = psthick
!X.Thick = psthick
!Y.Thick = psthick
!Z.Thick = psthick
!P.Font = 0 ; or 1, your choice
ENDIF

; Your normal graphics here. For example,
Plot, data

IF !D.Name EQ 'PS' OR !D.Name EQ 'PRINTER' THEN BEGIN
!P.Thick = thick
!X.Thick = xthick
!Y.Thick = ythick
!Z.Thick = zthick
!P.Font = font
ENDIF
END

If 3 is not the right value, then--at worst--you only
have to make a single change in your file. And you
could even put the value in as a keyword! :-)

Cheers,

David
