The original content of this article was on a page named "Mac OS X/Quartz". However, slashes are not to be used in article names (see Wikipedia:Naming conventions). As for the new name, I thought "Quartz (Macintosh)" was better than "Quartz (Mac OS X)" as Quartz is the technology while OS X is just one possible delivery mechanism. There is also System 7 (Macintosh) as another disambiguation page so using Macintosh here standardizes on the convention. RedWolf 03:55, Apr 12, 2004 (UTC)

Can people provide any sources for the claims in this article? It is my understanding that the imaging model is implemented in the higher layers (Cocoa), while Quartz only provides raw access to bitmaps and compositing primitives. Unless an authoritative source can be provided, this article needs a full rewrite.--Jec 03:07, 9 February 2006 (UTC)[reply]

Depends what you mean by 'imaging model'. Quartz is actually implemented in Core Foundation, which is a library accessible to all APIs, including Carbon (API). CF provides all the really low level imaging stuff such as handling rasterisation of vectors, compositing and so forth. However, there is enough there to draw pretty much anything - bezier curves, lines, text... Some of these are wrapped up by higher level Cocoa classes such as NSBezierPath, which makes Quartz easier to use, but you aren't required to use these. Carbon for example, uses CF directly, and QuickDraw maps down onto it at a very low level as well. Graham 03:14, 9 February 2006 (UTC)[reply]

I've updated this article and focused the discussion on Quartz 2D. I've documented sources. There was a lot of information missing, especially with regard to its relation to the compositor. Hope this is better! --Gerritdewitt 06:01, 28 January 2007 (UTC)[reply]

Remove "See Also"?

The "See Also" section seems redundant considering the current layout. I think it should be removed.--69.61.168.129 17:54, 4 June 2006 (UTC)[reply]

Use of PDF

I'd like to see someone with some technical knowledge of Quartz expand "Use of PDF". A lot of Apple documentation makes references to Quartz using or being based on PostScript and PDF.[1] It would be nice to see this section expanded a bit, since it's not clear how Quartz uses PDF, and how they are connected (or not connected, as the case may be).

(Also, incidentally, is there a reason why the "Quartz (graphics layer)" talk page redirects to the "Quartz 2D" talk page?) – Mipadi 18:25, 2 January 2007 (UTC)[reply]

Reason for disabling of Quartz 2D Extreme

Article stated "Quartz 2D Extreme is presently disabled because it currently offers only small practical performance improvements.[7]" - the citation given did not back up this statement in any way, it only "speculated" that it was disabled due to bugs, not lack of performance. I have seen no other reference to it being disabled due to lack of performance improvements. I changed it to reflect the reason stated by Apple in the release of OS X 10.4.3. 85.179.65.139 13:27, 19 August 2007 (UTC)[reply]
