A common cause of CG assertions on transforms is a 'Nan' or 'inf' value ending up in the transform (these may not be discovered until some funciton is called that uses the transform). This is pretty easy to cause, for example dividing by zero, by setting a scale of 0 in a transform. You really want to avoid this by sanitising parameters used to calculate transforms. Even having something apparently innocuous such as view frame rect of NSZeroRect can eventually cause a bad transform to be computed. That would be the sort of thing I'd be looking for here. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
