[time-nuts] DJVU and PDF

[Chris Albertson]

It's worth reading the documentation.

1) PDF is now an ISO standard.  Adobe created it but as of 2008 it is ISO.

2)  Look at the developer documentation for Mac OSX's "quartz graphic system.
Very loosely, what you do is open a contex and then send PDF drawing
comands to it.
This can be directed to the screen of a file.   The same is true of
IOS devices like
the iPad or iPod touch.  If you are a programmer you basically writte PDF to the
glass screen.
