Quartz's internal imaging model correlates well with the PDF object graph, making it easy to output PDF to multiple devices. Compositor research project at the University of Birmingham. It is widely stated that Quartz "uses PDF" internally (notably by Apple in Quartz's early developer documentation ), often by people making comparisons with the Display PostScript technology used in NeXTSTEP (of which Mac OS X is a descendant) and OPENSTEP. In theory it should be possible for different widgets to use the same compositor. It must be told everything about each composited quad - contents, location, transform, opacity, etc. Compositor knows nothing about the layer tree. This technology is known as Quartz Extreme, and is enabled automatically on systems with supported graphics cards. Compositor provides a cross-platform interface to a set of operations for compositing quads. In Mac OS X 10.2 and later, Quartz Compositor uses the processors (GPUs) on supported graphics cards to vastly improve composition performance. Quartz Compositor is the compositing engine used by Quartz 2D and other renderers, such as OpenGL, Core Image, and QuickTime. However, it still remains disabled by default, as there are some situations where it can degrade performance, or experience visual glitches it is a per-application setting which can be turned on if the developer wishes. As of Mac OS X v10.5 Quartz 2D Extreme has been renamed to QuartzGL. ![]() In Mac OS X 10.4, Quartz 2D Extreme is not enabled by default, because it may lead to video redraw issues or kernel panics. In Mac OS X v10.4, Apple introduced Quartz 2D Extreme, which allows Quartz 2D to use supported GPUs for rendering. 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. ![]() Quartz 2D is the primary two-dimensional (2D) text and graphics rendering library: It directly supports Aqua by displaying two-dimensional graphics to create the user interface, including on-the-fly rendering and anti-aliasing. ![]() In this use, the term covers Core Image and Core Video as well because the term is applied to a wide range of graphics technologies provided by Apple: In a more general sense, the term Quartz or Quartz technologies can refer to almost every part of the Mac OS X graphics model from the rendering layer down to the compositor. Because of this vertical nature, Quartz is often interchanged synonymously with Core Graphics. It includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card. Quartz specifically refers to a pair of OS X technologies, each part of the Core Graphics framework: Quartz 2D and Quartz Compositor. ![]()
