PostScript fonts

To be able to view or print a PostScript font in a TEX document, needs to know certain information about the font, especially the name of its corresponding TFM file. This information is specified in a configuration file on lines between begin_fonts and end_fonts; see the Default file. For dvips however, information about PostScript fonts is obtained from the psfonts.map file in :DVIPS:Inputs:. The PostScript TFMs stored in the PS subfolder in TeX-fonts are meant to be used in conjunction with virtual font files stored in the VF-files folder (section [*] has more information about virtual fonts). These TFMs and VFs were created for the psnfss package by Sebastian Rahtz using Alan Jeffrey's fontinst macros. The fonts are supplied in both OT1 and T1 encodings. The default encoding is OT1; this is the old TEX text font encoding described in The TEXbook. The OT1 TFM/VF files have names ending in 7t. The T1 (or Cork) encoding is the new TEX text font encoding for 256-character fonts. The T1 TFM/VF files have names ending in 8t. See test0.tex in the PSNFSS subfolder in TeX-inputs for how to select either encoding. Note that virtual font names should not appear in a configuration file's list of fonts, nor in psfonts.map. Only the corresponding ``raw'' fonts should be listed; these are indicated by TFM names ending in 8r. For example, when is processing virtual fonts in a DVI file created with the LATEX times package, it will use the commands in ptmr7t.vf to replace virtual characters from ptmr7t.tfm with actual characters from ptmr8r.tfm.
