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.
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 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.
Apple - Quartz Composer (User Guide) Quartz Composer is a node graph system provided as part of the Xcode development environment in macOS for processing and rendering graphical data. It is capable of making sophisticated animations for keynote or presentations and creating animated screensavers.
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.
Compiz introduced a cube effect, which allows the user to see up to 6 virtual desktops at once. Each desktop is converted into a surface texture of the cube, which can be rotated at will. Compiz displays a wide array of 2D and 3D effects and has relatively low hardware requirements. [18]
User's guide for a Dulcitone keyboard. A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images.
