That's 30 MB for *a single image*. It happens multiple times and adds up. Who notices? Me, but also my customers (really). The recently released rewrite of my app QuickPick uses Core Animation and Core Image. It's a document and application launcher. Should it be using 150 MB? No. That's clearly excessive. Why is it using 150 MB? A little bit is my slight misuse of CA thinking it's smarter than it is, but almost 100 MB is just from using Core Image instead of Core Graphics. If I remove just the blur filter, the memory usage isn't any lower. I can achieve the same effect (without the blur) using CG/NS and memory usage doesn't increase at all, as I would expect. > I expect Core Image is caching stuff for future use... I have the same thought, but if I kill off the filter and every other CI-related object, I'd expect that to go away. Creating new filters and executing it again isn't significantly faster. -- Seth Willits _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
