Re: FOP embed truetype font into postscript file

Could you tell me why Fop doesn't do embeding font into ps output,
what's the difficult thing in doing do so or dev-team is just being busy
with other tasks ?

If the API doesn't provide the necessary informations, then it will have
to be extended but we'll see that in a second step.

So I suggest you to start by having a look at the aXSL API, the code of
the PS renderer and the specifications of TrueType and Postscript. If
you have further questions then, just ask.

Actually, Type 1 embedding works for PostScript. It's just that so far
nobody needed TrueType support badly enough to do something about it.
