XeTeX: faked bold & slanted + request for ppc users

XeTeX: faked bold & slanted + request for ppc users

[Mojca Miklavec]

Hello,

I just wanted to let you know that XeTeX now supports both faking bold
and slanted (and the binaries on the garden minimals have that feature
already). It's generally a bad idea to use it, but in case that you
need it only for small portions of text (if you really have no other
way out), it could be handy. (Slanted is less evil to use than
"bold".)

The plain syntax is:

\font\a="Gentium"
\font\b="Gentium:slant=0.2" % better: \font\b="Gentium/I"
\font\c="Gentium:embolden=2"
\font\d="Gentium:embolden=2;slant=0.2"

Some time ago I have posted an example of the (current?) ConTeXt way to use it:

\definefontfeature
  [slantedandextended]
   % cloned from the rest of XeTeX, not really needed
  [method=node,script=latn,language=dflt,liga=yes,onum=yes,kern=yes,
   slant=0.25,extend=1.5]
\definefontsynonym
  [myfont]
  [file:texgyrepagella-regular][features=slantedandextended]

\starttext
\definedfont[myfont] This is slanted and extended
\stoptext

Also, I would be greatful if any mac ppc user could provide feedback
whether the cross-compiled xetex binaries on
http://minimals.contextgarden.net/current/bin/xetex/osx-ppc/bin/ work
ok.

Thanks,
    Mojca

hm, so it's embolden? in that case we need a remap to extend

i remember that taco and i discussed it with regards to luatex (i think 
that we even had a key in the tfm table at some point); i need to look 
into it

If I understand your question, extending the kerning for line
thickness is missing, yes (but maybe not desired in monospace fonts or
in Chinese, which is where the feature request came from, but in most
cases extended should be applied indeed). I wanted to ask that, but
I'm not sure about what is the most right thing to do.

I'm only guessing, but I also have a feeling that ConTeXt could
already support that feature per-se (with minor modifications).
Doesn't "outline fonts" in ConTeXt use exactly the same kind of
trickery as this "embolden" in XeTeX? (Only that outline only draws
outlines, while embolden draws the inner part (normal glyphs) +
outline.)

If you want to loosen the letter spacing slightly, just use something  
like

   \font\a="Gentium:embolden=2;letterspace=2"

Right, which is why it's not automatically applied.

no, i meant: slant and extend are the keywords .. similar to what 
happens in map files

ah, no idea ... extend normally scales the font horizontally (and 
therefore needs to widen the metrics); using outline trickery for faking 
bold sounds like a bad idea to me; anyhow, in mkiv that's not a font 
feature but a rendering option
