You aint suppose get transformation out from RenderingContext... you should
put it in..
Well here is trick how you can do things -
get size in inches, then get resolution of device, then get RC with 1:1
transformation,
measure string with 1:1 transformation (get measurement in device space) and
then just map
one size to another... Use this transformation right before drawString
Trick will not work for X-Windows thou.. Just because size there is broken
and antialiasing can just crack you up, when you apply it with fonts..
Cheers,
Sergei
