The drawing model utilized by Quartz 2D is based on PDF specification 1.4. [2] Drawing takes place using a Cartesian coordinate system, where text, vectors, or bitmap images are placed on a grid. [3] However, drawing output is not sent directly to the output device. Quartz 2D uses graphics contexts, environments in which drawing takes place.
In a general sense, Quartz or Quartz technologies can refer to almost every part of the macOS graphics model from the rendering layer down to the compositor including Core Image and Core Video. [2] Other Apple graphics technologies that use the "Quartz" prefix include these: Quartz Extreme; QuartzGL (originally Quartz 2D Extreme) QuartzCore

A video source provides a decompressed data stream to be rendered as images within a visual context in Quartz 2D. Core Video can be thought of as the link between this video source and its display context. Rendered images can be further processed by Core Image before being composed into a final scene with Quartz Compositor.
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.
