Greetings,

I was wondering whether there is a way to provide a proj4 string or other method for specifying a projection where the units are in pixels and screen width and height are provided?

Art,

There is no way I'm aware of to do this with the PROJ.4 functions,
nor with closely related mapserver/mapscript functions.  I'm not sure
if there is transformation code available from "further away from the
projections" portion of the code or not.

Best regards,
