Ok. I wasn't really thinking about plfreetype, but it is good to know that I don't have to :). Even though no one objected to adding 4 new functions to the dispatch table, I'm thinking that is probably not the best way after all. Instead I think the best way to do this is to add some new PLESC cases, something like: PLESC_BEGIN_TEXT PLESC_TEXT_CHAR PLESC_CONTROL_CHAR PLESC_END_TEXT Drivers can then chose whether they want to get all the text at once via PLESC_HAS_TEXT, or broken out character by character by PLplot core via the above. best, -Hazen ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
