Quartz technologies are at the heart of the Mac OS X graphics and windowing environment. Quartz 2D is a two-dimensional drawing API that leverages the Portable Document Format (PDF) drawing model and allows developers to to achieve many of the visual effects used in the Mac OS X user interface, including translucency and drop shadows. Quartz Composer is a development tool for processing and rendering graphical data. PDF Kit allows applications to display and manipulate PDF documents. Core Image and Core Video support, respectively, image processing and video image manipulation. Quartz also provides low-level system services such as window buffering and composition, event handling and dispatch, display management, and text rendering.
