As someone new to Context, I am trying to get to grips with font handling.
Reading through a fair amount of documentation it is not always to clear to me
what recommended practice in todays Luatex/MKIV enviroment is.
My setup is "Minimals" updated 26.7.2010 (luatex 0.60.2, MTXrun 2010.07.22)
setup on Mac OS X 10.6.4. I use it to produce documents I need in a language
teaching environment. As I am starting of without legacy documents, there is no
need for MKII or any other type of Tex.
Confusing for me is the use of "\definebodyfont" in typescripts. I read in
"co-fonts.pdf" (no release date, internal creation date 18/11/2009):
"because Latin Modern comes in design sizes, there was a need to associate a
specific font with each bodyfont size. You may find yourself in a similar
situation when you attempt to create a typescript for a ‘professional'
commercial font set."
Looking at the example:
\definebodyfont [10pt,11pt,12pt] [rm] [tfe=Serif at 48pt, ite=SerifItalic at
48pt]
\tfe Big {\it Words}.
What I simply don't understand is the need for multiple font size declarations.
I can (kind of) see that it might be necessary (looking at typescripts), if the
whole typescript resolves to "design sizes" where each point size is a single
font file. But for ttf/otf fonts, ie. where the font is scaled?
This minimal example, including a "special" font (TitleFont) works (almost)
fine for me.
% the only two statements to declare the fonts I want to use
\usetypescriptfile[type-otf] % being default, I could even miss this
declaration
\setupbodyfont[pagella,10pt]
\definefont [WonderFont] [BoldItalic sa 4.8]
\starttext
{\WonderFont The Big Title}
\input aesop-de
\stoptext
I do get one consistant error (the "5pt" can vary depending on the size I give
in "setupbodyfont"):
{/Users/martin/contextMini/tex/texmf-context/fonts/map/pdftex/context/mkiv-px.map}
virtual math > the mapping is incomplete for 'pxmath' at 5pt
Though, the document looks fine. Does the error hint I am missing something?
What is "good practice" in Luatex/MKIV to access the desired fonts?
My questions:
- when do I need to use the multiple point sizes at all in a Luatex/MKIV
environment?
- when would I need to provide that information in typescript files I need to
create? (simplefonts is very slow to load fonts with phonetic symbols)
Any tips to help my understanding would be appreciated!
