I
find fonts one of the
most miraculous bits of
the way the Mac works
... the greatest part
of the miracle is that
they work so smoothly
without the user needing
to know anything about
what goes on under the
bonnet ... Actually
they work pretty well
under Windows too, partly
thanks to Apple technology
...
Originally,
a computer type-face was
described in a fixed number
of pixels
working
like Photoshop, Fireworks
or a Claris/AppleWorks
painting module
called
a 'bitmap' font: it only
works properly at one
size, you can't scale
it satisfactorily.
So
there has to be
a different font
for each size, the
type-designer creates
separate drawings
for italic, bold
and bold-italic
versions, and they
have their own fonts,
too, again separately
at whatever sizes
are needed.
