I am looking for similar information. I would like to conver Ink to
either a BMP/GIF/PICT image. Is there any PD/shareware converter which
does this already. What about the Newtons built in Print command which
can print individual strokes to Postscript printer. Can I redirect the
postscript to a file and convert it to EPS, then load it in xv and do
the conversion.

: Essentially, Apple has not released the format of Digital Ink. Perhaps if
: you e-mail them they'll do it under non-disclosure. Otherwise, you are
: correct (this has been discussed here a few months ago), you must capture
: with a viewClickScript a points array (PIE has a good example sample of
: this).
A representative from Paragraph stated this info is not available. Since
they're the folks that created the ink mechanisms for Apple I'd go with
this info. The ink format is a form of compressed splines. 6 bit I
believe. You'd go banannas figuring it out. (trust me on this)
You cannot, at this time, get any decent info from an ink object. The
data is in there, but no Newtonscript tools exist to access it. It's
likely this would improve in OS upgrades.
Meanwhile your only alternative is to grab the points on the fly and
store them on your own. This is slow and tedious. Compiling helps.
Better OS calls help more. Ah well.
