Follow up summary. So far it seems to me, from my recent experience, that .. cr.device_to_user(x,y); //where cr is a Cairo.Context .. actually works, and that there is no equivalent way to do this in situations where you have no context. I have tried the suggested manual formulas, as well as the "invert then transform_point" approach. (Thx, btw.) Neither have done what the cr.device_to_user does. (And I'm likely the reason for any bugs.) "How can I take a pair of coordinates in device space into user space (by way of a pre-saved matrix) in some handler that has no access to the Cairo Context?" Is my wording of the problem clear? I'm not sure because math. :) \d -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
