Thanks for the input on the INK format. I have not verified
the print observation, but it matches the first.

Has anyone had any experiences with binary storage of vector
data? I don't even know where to start!

I am almost done hacking the APPT.ADB format (Over and above
what A. Gryc has specified.) I will present my findings when
I am done.

Now back to my real job... <sigh>

I imagine the format INK data would be very interesting. I don't know if
anyone else has noticed this but
1. There can only be a certain amount of 'Ink' on the screen at any one time
(just try colouring in the whole screen)
2. If you draw something on the screen and then change the pen size in
setup, what you have already drawn gets changed.
It seems that it could be a hybrid vector/bitmap monster rather than a
simple GIF(89) file or something.

Anyways, that my two cents worth.

I believe the ink is in a vector format, if you print out a page with
ink on it you'll see that it isn't smooth its a collection of
straight lines. I could be wrong it might just be placed in a raster
format after the data is entered in via vectors so it can be erased.

Well good luck,
