interaction between \tfx and \os (2nd try)

interaction between \tfx and \os (2nd try)

[Bill McClain]

I've found a strange interaction between \tfx and \os: when using both
commands in combination the text is smaller than it should be. I believe
the commands were working correctly earlier in the year.

Tested with ver: 2002.7.26. The example output (75k) is at:

    http://home.salamander.com/~wmcclain/example.pdf

The test shows Computer Modern, Sabon and Jenson examples. It is
particularly instructive to look at the Jenson lines.  My Jenson has no
old-style figures and my typescript simply maps [OldStyle] to the same
font file as [Serif]. So regular and \os text should be the same
characters, but when used in combination with \tfx, the \os text is
smaller.

\tfa works as it should, as does setting the font size explicitly with
\switchtobodyfont.

Here is the source:

* * *

\usetypescriptfile[type-sabon]
\usetypescript[Sabon]

\usetypescriptfile[type-jenson]
\usetypescript[Jenson]

\def\Digits{0123456789}

\starttext 
\startlines

% \tfx \os combination text is very small
Computer Modern
normal \Digits\ {\os \Digits} 
tfx {\tfx \Digits\ {\os \Digits}} 

\switchtobodyfont[Sabon]

% \tfx \os combination text is very small
Sabon
normal \Digits\ {\os \Digits} 
tfx {\tfx \Digits\ {\os \Digits}}

\switchtobodyfont[Jenson]

% \os text should be identical to regular, but when 
% in \tfx it is smaller
Jenson
normal \Digits\ {\os \Digits} 
tfx {\tfx \Digits\ {\os \Digits}} (should be same size!)

% \tfa works as it should
Jenson
normal \Digits\ {\os \Digits} 
tfa {\tfa \Digits\ {\os \Digits}}

% setting explicit point size works as it should
Jenson
normal \Digits\ {\os \Digits} 
8pt {\switchtobodyfont[8pt] \Digits\ {\os \Digits}}

\stoplines
\stoptext

i'll look into it, can you try:

\definefont[os][OldStyle]

That makes a difference. The CM and Sabon \tfx \os text is more
reasonably sized and the Jenson example appears to be the same size with
and without \os, which is correct.

There is a side effect: the Jenson \tfa \os combination reduces the text
just slightly (compared to just \tfa), which shouldn't happen.

I don't use \definefont anywhere in my typescripts or jobs. Should I?

Hi,

In cont-sys.tex, after \unprotect, add:

\def\@fs@sa
   {\scaledfont\normalizedbodyfontsize  % was \fontbody
    \setsamofontspec}

and also:

\def\dodefinefont[#1][#2][#3]% [name][spec][1.6 | line=10pt | setup_id]
   {\doifinstringelse{ }{#2}
      {\ifthirdargument
         \unexpanded\setvalue{#1}{\redodefinefont{#1}{#2}{#3}}%
       \else
         \unexpanded\setvalue{#1}{\dododefinefont{#1}{#2}}%
       \fi}
      {\definefont[#1][#2 sa *][#3]}}

Please test this extensively, works ok with:

{x123 \os x123} {\tfa x123 \os x123} {x123 \tx x123 \os x123}
\definefontsynonym[OldStyle][Serif]
{x123 \os x123} {\tfa x123 \os x123} {x123 \tx x123 \os x123}

well, it can be handy in situations like:

\definefont [MyBigTitleFont][Serif sa 5]

and alike; optionally

\definefont [MyFont] [StrangeFontThatDoesNotFitInScheme at 12pt][line=16pt]

(or even:

\startsetups[oeps]
  whatever kind of settings
\stopsetups

\definefont [...] [...] [oeps]

as experimental feature)

You can then pass such fonts as styel option

OK, then, to go back to my earlier questions that never got answered:

In the above example "MyFont" is the font synonym (in my case "Footnote"),
and the "Strange...." part is the actual file name for the tfm?

If I want to use the font in a document, then, all I should need to do is to
use a fontswitch command (in this case for footnote numbers) and specify
"Footnote" (or MyFont, or whatever)?

Which just makes font switching a little easier?

This is not quite right on my system. The original buggy behavior is
restored. Actually, it may be an interaction with my typescripts. \tfx
shrinks the CM text, but does not shrink the Sabon or Jenson text unless
\os is also applied.

The interaction with \tfa I mentioned previously is fixed.
