Subject: [metafont] dc fonts for the MacIntosh

Hello,

I work more or less as resource person for LaTeX.

I am personally using MiKTeX under windows; but somebody
asked me about a problem with TeXtures on a Mac.

That person receives files created with ScientificWorkplace.
Very often dc fonts are used and they are automatically replaced 
by other. On the Mac one uses PostScript fonts.

Bluesky (creator of Textures) doesn't have a solution.

Any help?

Thanks

Alain Delmotte

Subject: [metafont] MetaPost bug fix in the graph.mp macros

I have fixed a bug the setrange command whereby nonzero lower bounds
and upper bounds greater than about 10000 caused the lower bounds to
get messed up.  For example, a command like this can often cause the problem:
  setrange(110,110,"22000","22000");

I have updated the master copy of graph.mp in
    http://netlib.bell-labs.com/netlib/research/metapost.tar.Z
and this should show up automatically in CTAN and various other places
as metapost.tar.gz (or something like that).
Since this is just a change in the macros, it does not really count as a new
version of MetaPost.

I do *not* recommend that casual users go to these master distributions.
They are hard to install and serve mainly as a place for maintainers of
TeX/LaTeX/METAFONT/MetaPost distrubtions to get their raw material.
If you want to try it right away, just give the following macro
redefinition after   input graph

Subject: [metafont] MetaPost Graph Tick Label Font Size

I cannot figure out how to change the font size used for the tick mark 
labels (e.g. 0.1,0.2,...) with the Graph package for MetaPost.  I would 
like to make the tick mark labels larger, but saying 
"defaultscale:=1.8" doesn't seem to work.  I am using "MetaPost (Web2C 
7.3.1) 0.641" as part of the Fink port of teTeX on MacOS X 10.2.2. Any 
ideas on how to do this or why it might not be working?

Thanks!

The _d_c fonts are ancient and obsolete; CTAN holds a replacement
of them with virtual fonts. The newer implementation are the _e_c
fonts.

Really? Use the cm-super package (also on CTAN) and educate BSR. :-)

Hello,

The problem is not to create new documents with dc
but showing on screen and printing .dvi files in which
the dc fonts has been used.

Your only hope is the dc-replacement with virtual fonts based on
the cm fonts (which are available as Type 1) which once existed
on CTAN (I can't find them anymore).

Subject: [metafont] dc fonts on the MacIntosh



Salut Alain Delmotte, Martin, and others

 > The problem is not to create new documents with dc
 > but showing on screen and printing .dvi files in which
 > the dc fonts has been used.

To have a well defined problem we should know with which
OS and implements the viewing and printing are desired.

Not knowing better, I will focus on the font requisites for 
deriving type1 based ".pdf" files, as the latter are *widely* 
useful for printing and viewing. 

     The old dc fonts are nearly compatible with the new ec
fonts. Free type 1 ec fonts are found on CTAN in

         tex-archive/fonts/ps-type1/cm-super

and also (for example) in the Bakoma TeX distribution

        tex-archive/systems/win32/bakoma/

In exploiting the dc ".dvi" files, the dc -> ec correspondence
should be established via a font substitution table, which I
hope you submit to CTAN once it is debugged. It is not so easy
to construct because there is a wild nomenclature shift in
going dc -> ec.  I believe the metric differences at the ".dvi"
level are negligible.

     To my knowlege, there is no virtual dc font set. 

     Unfortunately, to process the dc DVIs, one will have to
leave the Mac platform. Indeed cm-super fonts are not
available on Mac.  Why?  Because Mac font metrics (i.e. FOND
resources and a bit more) are needed, and these are are poorly
understood, except perhaps by Y&Y. Berthold?

Cheers,

Laurent S.

PS. Perhaps (tetex for MacOSX) and/or (CMacTeX) now uses ".pfb"
files directly for PS and PDF production? That seems a
development much to be encouraged; Textures for Mac OSX will
surely support it ;=).  Also, maybe the Mac FOND
hassle will be resolved by an afm->FOND converter.

PPS. Impeccable Textures solutions are available for French 
(and more) by using the virtual "ae" fonts on CTAN; they are 
CM based and T1 encoded.  BUT TeX recompilation is needed here 
since I believe they are *not* sufficiently metrically 
compatible with "dc".
