Presently, the name Quartz 2D more precisely defines the 2D rendering capabilities of Core Graphics (Quartz). With the release of Mac OS X 10.2, marketing attention focused on Quartz Extreme , the composition layer, leaving the term "Quartz" to refer to the Core Graphics framework or just its 2D renderer.
The bitmap output from Quartz 2D, OpenGL, Core Image, QuickTime, or other process is written to a specific memory location, or backing store.The Compositor then reads the data from the backing stores and assembles each into one image for the display, writing that image to the frame buffer memory of the graphics card.
Quartz can render text with sub-pixel precision; graphics are limited to more traditional anti-aliasing, which is the default mode of operation but can be turned off. [3] In Mac OS X 10.4 Tiger, Apple introduced Quartz 2D Extreme, enabling Quartz 2D to offload rendering to compatible GPUs.
The Quartz Composer 3.0 interface. Also new in Version 3.0 was the possibility to write custom patch plugins using an Xcode template, and the notion of a "safe mode" where plugins and other unsafe patches fail to load.
Core Image is a pixel-accurate, near-realtime, non-destructive image processing technology in Mac OS X. Implemented as part of the QuartzCore framework of Mac OS X 10.4 and later, Core Image provides a plugin-based architecture for applying filters and effects within the Quartz graphics rendering layer.

Cairo supports output (including rasterisation) to a number of different back-ends, known as "surfaces" in its code.Back-ends support includes output to the X Window System, via both Xlib and XCB, Win32 GDI, OS X Quartz Compositor, the BeOS API, OS/2, OpenGL contexts (directly [7] and via glitz), local image buffers, PNG files, PDF, PostScript, DirectFB and SVG files.
Rendering APIs typically provide just enough functionality to abstract a graphics accelerator, focussing on rendering primitives, state management, command lists/command buffers; and as such differ from fully fledged 3D graphics libraries, 3D engines (which handle scene graphs, lights, animation, materials etc.), and GUI frameworks; Some provide fallback software rasterisers, which were ...
The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++. Skia abstracts away platform-specific graphics APIs (which differ from one to another). [ 1 ] Skia Inc. originally developed the library; Google acquired it in 2005, [ 2 ] and then released the software as open source licensed under the New BSD free software ...
