I'd like to suggest a different approach if things cannot be tuned to have far fewer draw calls. Font caching etc. is very fast, but not as fast as it could be given the choices it has to support. I think you said you had one font, one size. I'm guessing you also have no more than 256 different characters you might show (but consider where in the world your customers are...)
If so, perhaps you could simply have a table of 256 images, and paint them to screen in the fastest possible way. Now, that's a lot of code to write speculatively, but you can see if it will save time by replacing every paint text call with a call to paint a single fixed image. If it goes fast enough it may be worth this approach. (I'm sure there are fast and slow ways to paint images too: grid aligned, unscaled, colour model matching - maybe some of these can be optimized. Monochrome mask painting might be faster, or slower). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
