[comp.text.tex] DVI previewers supporting virtual fonts?

ilh@winnie-the-pooh.mit.edu (I. Lee Hetherington) (02/11/91)

I'm learning how to use PostScript fonts with dvips through the use of virtual
fonts (to correct for the different locations of ligatures...I think). Anyways,
dvips works fine.  Unfortunately, xdvi doesn't support virtual fonts.  Anybody
modify xdvi to support virtual fonts?  Any other previewers support virtual
fonts?

I'm trying to preview some PostScript fonts for which I have bitmaps for screen
previewing.

Any help is greatly appreciated.

This method is, unfortunately, inadequate.  The program dvicopy
``converts a DVI file referencing VF fonts into a DVI file which does
not contain such references'' according to the dvicopy.readme file.
At some point, xdvi requires GF or PK files; therefore, to display
PostScript fonts one must convert them to one of these formats.

This issue will resolve itself when someone writes the X-Windows
equivalent of Rokicki's dvips.  None of the existing display programs
can claim equivalence.  xtex displays X11 fonts, but cannot read GF or
PK files (an unnecessary defect and inconvenience, in my opinion), and
xdvi does the latter, but not the former.  The ultimate xdvi/xtex
program should have both these capabilities, plus a dvipage-like low
pass filter for a quality display.

Use the dvicopy program by P Breitenlohner.  It copies a dvi file
``expanding'' characters from virtual fonts to the corresponding
non-virtual font characters, movements and rules.  I have heard that
it is available as part of the web2c package.  Or get it by ftp from
here (tik.vtt.fi:~ftp/pub/tex/dvicopy.{web.Z,ch}.

I know that, but the original question said:

So this isn't a problem in his case.
