I am trying to bring up TeX on our system in cooperation with
a Laserwriter-compatible printer. Along with the UNIX TeX
distribution, I received a tree of files relating to producing PS from
TeX .dvi files using PS fonts (a filter called "psdvi"). The tree
included loads of .tfm (TeX font metric) files with names like
"Helvetica.tfm". Unfortunately, TeX is looking for scaled files with
names like "Helvetica9.tfm" for 9-point. As most of TeX is a black
box to me (TeX in yields dvi out, and hopefully the right filter
yields postscript from that), could some kind soul tell me what I need
to due to create the scaled .tfm files?
The distribution stuff I got includes a version of dvi2ps, but
I would much prefer to use psdvi and PS fonts, for cleaner, faster,
and shorter print jobs. The tape also included Metafont, a bunch of
mf utilities, etc.

From article <8634@cadnetix.COM>, by pem@cadnetix.COM (Paul Meyer): " ... " TeX .dvi files using PS fonts (a filter called "psdvi"). The tree " included loads of .tfm (TeX font metric) files with names like ""Helvetica.tfm". Unfortunately, TeX is looking for scaled files with " names like "Helvetica9.tfm" for 9-point. ... That's odd. I don't have the latest version of TeX, but mine looks for any file <name>.tfm you give it, by issuing a command `\font\myfont=<name>'. If the command was `\font\myfont=Helvetica', then, TeX should look for the file named Helvetica.tfm, and would assume a point size given as the default or design size within that .tfm file, probably 10 points. Since Adobe fonts are scalable, the natural way to specify a different point size is with the `at' argument, as in `\font\myfont=Helvetica at 9pt', in which case TeX will scale the dimensions given in the Helvetica.tfm file down (in this case) appropriately, and it's up to your PS driver program to pick up the information TeX leaves in the .dvi file and issue corresponding PS commands that ask for 9 point Helvetica (or whatever size gives that in effect). At least, this is how my version of dvi2ps works -- I haven't used psdvi. Greg, lee@uhccux.uhcc.hawaii.edu

TeX is looking for Helvetica9 because somebody wrote the macros as \font\sf9=Helvetica9 (or something like that) Instead, rewrite them as \font\sf9=Helvetica scaled 900 and you'll only need one tfm file per face. Naturally, the dvi backend has to know the right thing to do. | The distribution stuff I got includes a version of dvi2ps, but |I would much prefer to use psdvi and PS fonts, for cleaner, faster, |and shorter print jobs.

The .tfm files for psdvi are set up for a 1-point design size, so for 9 point Helvetica, you'd say \font\foo=Helvetica at 9pt The version of dvi2ps that handles Adobe fonts uses similar .tfm files set up for a 10 point design size. This has the advantage of making font scaling look the same for Adobe and CMR fonts. -- Amanda Walker <amanda@intercon.UUCP> InterCon Systems Corporation -- "Those preachers are right--there's more in these songs than meets the eye..." --Arlo Guthrie

TeX only accepts letters in symbols, not digits, so trying to use "sf9" as the TeX symbol that refers to the font will result in TeX using the symbol "sf", and screwing up trying to find the font "9=Helvetica". 2. Some implementations use a 10pt default size for PostScript fonts, but most of those that I have seen use a 1pt (the PostScript default size). On the latter, asking for "scaled 900" will of course give you a 0.9pt size font, which is som small that it is hardly visible. The following, syntactically correct, definition should give you a 9pt size Helvetica on both kinds of implementations: \font\ninesf=Helvetica at 9pt Jan Michael Rynning, jmr@nada.kth.se Department of Numerical Analysis If you can't fully handle domains: and Computing Science, ARPA: jmr%nada.kth.se@uunet.uu.net Royal Institute of Technology, UUCP: {uunet,mcvax,...}!nada.kth.se!jmr S-100 44 Stockholm, BITNET: jmr@sekth Sweden.

Correct again. I had forgotten that psdvi uses a base size of 1 pt. Our filter uses a more reasonable default of 10 pt. To avoid problems, state the point size explicitly as recommended.
