Sounds (and looks!) interesting, Hez! Is this global transform applied before, after, or instead of the "pltr" type transformations?
It looks like the global transform function has the same signature as the "pltr" transform functions so that the predefined pltr1, pltr2, etc. functions can be used as global transformation functions. Do you envision this global transform capability supplanting the individual pltr parameter in the functions that currently support it? Thanks, Dave On Apr 11, 2010, at 22:56 , Hezekiah M.
