An integer that specifies the graphics text font system to use.
Set FONT equal to -1 to select the Hershey character fonts, which are drawn using vectors.
Set FONT equal to 0 (zero) to select the device font of the output device.
Set FONT equal to 1 (one) to select the TrueType font system. See Fonts for a complete description of IDL's font systems.
Using PostScript Fonts
To use a PostScript font in your Direct Graphics output, you must first specify that IDL use the device font system, then switch to the
PS device, then choose a font using the SET_FONT keyword to the DEVICE procedure.
The following IDL commands choose the correct font system (0 designates the device font system), set the graphics device, select the font Palatino Roman, open a PostScript file to print to, plot a simple data set, and close the PostScript file:
!P.FONT = 0
SET_PLOT, 'PS'
DEVICE, SET_FONT='Palatino-Roman', FILE='testfile.ps'
PLOT, INDGEN(10), TITLE = 'My Palatino Title'
DEVICE, /CLOSE
