# Virtual font

Virtual fonts are imaginary fonts to use various format of fonts in TeX such including PS fonts. Usually a dviware replaces the virtual font by an actual font according to the information in the virtual font file (with the extension vf or ovf in case of Omega).
To use virtual font in dviout, set -virtual: (Property Sheets->[Font2]) ON and indicate in TEXPK: the place of VF files (^s.vf or ^s.ovf) and the fonts referred by the VF file.
(For example, see Q_F14).
The fonts referred by VF file are shown with an indent by Font Information(Help->Font Info).
These fonts can be made by Automatic Font Generation (-gen:).
If PSNFSS(the package to use PS fonts in LaTeX) is used, it is convenient to define a mktexpk command corresponding to gsftopk in -gen:. The location of the generated fonts should be indicated by -TEXPK:.
