Thanks Alastair and Graham for responding, and apologies for the delay in following up.
I think that, at best, the documentation is ambiguous. It would be clearer specifically saying "If no value was set explicitly for the receiver, this method [lineWidth] returns the default line width ->at the time the receiver was created<-" I may file a RADR on that. It is further confusing because the actual effect of the lineWidth property is dependent on the view in which the drawing takes place -- that is, a line width of "1.0" in one view will not necessarily appear the same width in a separate view that has a different dot-pitch, pixel ratio, etc. > From: Graham Cox <graham....@bigpond.com> > Date: Thu, 23 Apr 2009 10:27:25 +1000 > To: Tobias Zimmerman <automa...@gmail.com> > Cc: "cocoa-dev@lists.apple.com" <cocoa-dev@lists.apple.com> > Subject: Re: Removing or ignoring "lineWidth" property of an NSBezierPath > instance > > > On 23/04/2009, at 7:19 AM, Tobias Zimmerman wrote: > >> (By way of further explanation, the project this arises in involves >> a set of >> bezier paths that are generated in one program and archived for use >> in a >> separate program.
