Core PS/PDF Fonts

You can get really small output using the core fonts, which I'm sure
some users appreciate. They are also problematic, since not everyone has
a copy of the exact right fonts, and the viewer program substitutes
something else that has (or should have) the same metrics. Thus a figure
that you like on screen might look very different when printed (possibly
via a professional printer that does have a copy the real Helvetica
etc). To avoid such problems, some publishers require all fonts to be
embedded, and the latest version of the PDF spec deprecated the use of
the core fonts without embedding them.

If experience is any guide, you won't hear from the people who depend
on it until you remove support (plaintive pleas to the mailing list
notwithstanding). The old timers love their small PS files, and we
support this because many people have asked for it. I hesitate to
remove support lacking compelling justification, though I prefer the
embedded solution myself.

Hi,

If experience is any guide, you won't hear from the people who depend
on it until you remove support (plaintive pleas to the mailing list
notwithstanding). The old timers love their small PS files, and we

I am just pondering if it is a compelling enough reason to add support for it to mathtex -- as the only use for AFM support would be specifically for embedded PS/PDF fonts.

Would this be a valid alternative: bundling fonts with similar metrics as the PS fonts (we already have some unicode fonts in mathtex) and then on the matplotlib side choose not to embed such fonts. So mathtex works in terms of .ttf fonts, but at the matplotlib end of things it can opt not to embed them.

This way we retain support for the feature with no additional demands on mathtex.

Regards, Freddie.
