Hello,
Looking though the Sketch example, I notice that they are saving and
restoring the graphics context. My understanding is the GC describes the
way in which drawing operation are to be performed.(ie transforms.) But
does this some how give double buffering as well?
Also I what to render bezier paths to an image, for copying into other
apps. Is this as simple as locking focus to an image, perform the
drawing operations and unlock. Or am I missing the point with how
quartz works...
thanks,
Ruben
