Automatic selection of font shape depending on size

Automatic selection of font shape depending on size

[Victor Figurnov]

Dear All!

Is there in ConTeXt an equivalent of LaTeX2e automatic
selection of font shape depending on font size?

For example, the following LaTeX statement (from type1ec.sty):

\DeclareFontShape{OT1}{cmr}{m}{n}{
        <-6>    cmr5
        <6-7>   cmr6
        <7-8>   cmr7
        <8-9>   cmr8
        <9-10>  cmr9
        <10-12> cmr10
        <12-17> cmr12
        <17->   cmr17
      }{}

means: for cmr family in OT1 encoding (series=medium,
shape=normal) LaTeX will use:

   for font sizes < 6pt use (scaled) external font cmr5 
   for font sizes >= 6pt and < 7pt,  use (scaled) external font cmr6
   for font sizes >= 7pt and < 8pt,  use (scaled) external font cmr7
   . . .
   for font sizes >= 12pt and < 17pt, use (scaled) external font cmr12
   for font sizes >= 17pt, use (scaled) external font cmr17).

For example, if 5,5 pt font size of cmr font family in OT1 encoding
(series=medium, shape=normal) is needed for typing text or math,
LaTeX will automatically use external font cmr5 (cmr5.tfm), scaled 
to 5,5pt design size. For 24 pt font size -- external font cmr17
scaled to 24pt design size, etc.

Is there in ConTeXt something like this?

In type-siz.tex I see this:

% cmr 

\starttypescript [serif] [computer-modern] [size] 

\definebodyfont [12pt] [rm] 
  [tf=cmr12,
   bf=cmbx12,
   it=cmti12,
   sl=cmsl12,
   bi=cmbxti10 at 12pt, 
   bs=cmbxsl10 at 12pt, 
   sc=cmcsc10 at 12pt]

I guess it does what you want.

And in type-enc.tex I see this:

\definefontsynonym [Times-Roman] [\typefaceencoding-utmr8a]
				   [encoding=\typefaceencoding]

Perhaps it does the same for scalable fonts.
