 | | Quartz 2D running in software using the CPU has to write to the backing store in RAM, then that backing store has to be moved to the video card where the Quartz Compositor can put it into the final scene. | | | Quartz 2D was notoriously slow at drawing lines in Panther and earlier versions of Mac OS X, so much so that developers often chose to use (or in most cases, "stick with") QuickDraw for such tasks. | | | To the operating system, VRAM looks a lot larger than it actually is. Quartz handles the details of swapping data in and out of VRAM as needed, using a replacement algorithm tuned to keep the most frequently used pieces of data in VRAM as much as possible. |

| | Since the Quartz Compositor only works with rasterized data (i.e., bitmaps), the result of every drawing command must be stored as a bitmap in a memory buffer somewhere. | | | The Quartz software was further optimized in Mac OS X 10.1, and the hardware got marginally faster. | | | In order to comply with the conceptual model of Quartz, the area under transparent window had to be re-composited every time either the window moved or another frame of video was displayed. |

| | Graphics & Imaging Overview |
| | Quartz is the powerful graphics technology family that forms the foundation of the 2D imaging model for Mac OS X. Quartz offers two integral parts, the sophisticated Quartz 2D drawing engine and the Quartz Compositor advanced windowing environment. | | | Quartz 2D is also extensively used by Mac OS X's printing system where its device-independent and resolution-independent nature creates professional quality printed output. | | | The Quartz Compositor is an advanced windowing system that manages the onscreen presentation of Quartz 2D, OpenGL, and QuickTime content. |

| | Quartz composer works with the graphical interface in which objects are boxes; their properties at any given moment are the outlets of these boxes and any parameter the object accepts as input is represented through an inlet. | | | Quartz itsself indeed is most probably in no way depending on composer. | | | Quartz has viewpoints and a reasonably conventional programming API. |

| | OS X Odyssey 231 - The Quartz Extreme Conundrum |
| | The window compositor has been moved from the CPU to the graphics processing unit for improved system performance. | | | In earlier versions of Mac OS X, the Quartz Compositor operated entirely in software and used the central processing unit (CPU) to position window content on individual layers. | | | Quartz delivers crisp graphics, anti-aliased fonts, and blends 2D, 3D and QuickTime content together with transparency and drop shadows. |

| | ONDotnet.com -- Graphical Composition in Avalon |
| | You do not have to invoke the Quartz compositor to do this, the Quartz compositor is used for different tasks. | | | For someone that claims to have developed with Quartz, I find it odd that you were so displeased with Quartz you came to the conclusion that a six-year wait for a technology to do your work is not that big of a deal. | | | Whatever the reason, the Quartz compositor is (essentially) just for handling what you would refer to as "top level" windows and how they interact. |

| | creativepro.com - Under the Desktop: Prospecting for Quartz in Mac OS X |
| | Quartz distinguishes itself from Windows computers and even graphics workstations through its handling of layered color information and the internal use of an independent imaging model, in this case, PDF. | | | Quartz has two main parts: a Core Graphics Services component that keeps track of each window and its contents, and a Core Graphics Rendering component that decides what goes inside each window. | | | A software controller, called a "service" in Unix lingo, tracks the contents of each window on the screen, pixel by pixel, retaining any information about translucency (the good old alpha channel) and anti-aliasing data for text. |

| | The way the Quartz Compositor is designed, any drawing engine could be added to hand it graphics to display. | | | Apple removed all drawing, including the PostScript language, from the core window engine, and introduced a "lightweight window server," called the Quartz Compositor. | | | If Apple has any plans to exploit the latent possibility of remote display functionality in Mac OS X's Core Graphics, they are keeping it a tight secret. |

| | This is only an issue if you have a transparent window on top of your application’s window that is flushing it’s content and the Quartz Compositor needs the content of your application’s window (even though it has not flushed yet) for the composition. | | | Control returns to the application while the the Quartz Compositor (window server) uploads the affected regions to video memory. | | | The Quartz Compositor just needs a read lock for the compositing operation. |
