Hi Mojca,

...

Also, is there a way to directly get the glyph outlines of, say, $\bigotimes$ in MetaPost code and use it to derive some length unit from it?

Yes, but this only works for Type1 fonts, not for OpenType.

The example below is a literal copy from metapost manual (created by Taco).

This is quite impressive! This will make it much easier for me to obtain the right dimensions… Now if only this worked with OpenType as well (or any other font format ConTeXt understands natively)… and it would be really great if direct access to outlines extended to arbitrary typeset material beyond single glyphs. I know there used to be a TeX -> PS -> pstoedit -> MetaPost workflow. Does this still work with MkIV? Oliver

If you manage to extend dvips to handle OpenType fonts then maybe ...

So does this mean that outline fonts in MetaPost are currently dead with MkIV? Oliver

it's unrelated to tex ... outlines are ther ebecause of the svg output mode of metapost and so providing access made sense; opentype is another matter Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

I just said that pstoedit workflow is not likely to work with OpenType fonts, nothing else.

why not? it uses gs for converting the shapes to outlines ... works ok Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hans I will check it with Symbola http://users.teilar.gr/~g1951d/Symbola.zip Given that I'm lazy

May I bet that Alan is using linux for which I need Hans' build for which it might be polite of me to send him new building scripts since the current ones fail (the old version of svn on debian sarge doesn't recognize some of the options)?

Sorry guys, but it's too late today.

ok, i will do it tomorrow Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

At some point next year I will rewrite the font backend of luatex, and at the same time make it a bit more generic. Once that is done, the new code can be ported to metapost. Don't hold your breath, it will likely take more than a year. Best wishes, Taco
