This is a possibility, although to some degree this is likely due to differences in the GPU (that is, I would expect that Core Animation is still setting the proper flags, but the mobile GPU doesn't do as nice a job as the one on your desktop machine). It may make more sense to take this from a different angle, for example why do you need a bitmap context in the first place and why does it need to be larger? There may be better ways of handling this case. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
