Yes, and no.
There is no driver to do direct drawing in PDF, as with the PostScript
backend. But there is a support-driver bundle:
that handles color-changes.

Yes. The dots + lines + arrowheads works very well, with the hinted
Type1 fonts providing the building blocks.
Together with the available color support, this is enough for most purposes.
If anyone wishes to provide full object-oriented drawing capabilities
in PDF --- that is, a true PDF back-end for Xy-pic --- then I'd be glad

(The difficulties in this task stem from the lack, in PDF, of the
programmable structures available with PostScript.)
Hope this helps,
