[comp.sys.mac.programmer] Hi Res! How's your greyscale?

pes@cs.nott.ac.uk (Peter Sutton) (07/20/89)

Writing a printer driver (old system 6!).

How do I print greyscales and high resolution images (>72dpi).
The typesetting markup language that I use can cope with high res and
greyscale.
What I want to know is how to 'con' the mac into giving me the data from
the original scanned in bitmap (which is grey levelled and / or resolution
greater than 72dpi).

Do I set resolution in my printing grafport (at present set to 72dpi so that
I can set the pen position in the markup language using points - units of 72
dots per inch) or some other dodge?

(Ignoring for present those applications that use PDEF7)

Thanks
Peter Sutton
