Quartz 2D Reference Collection

Quartz 2D is an API that makes the Quartz advanced drawing engine accessible from all OS X application environments outside of the kernel. It provides low-level, lightweight 2D rendering with unmatched output fidelity regardless of the display or printing device. The Quartz 2D API supports transparency layers, path-based drawing, transformations, offscreen rendering, advanced color management, anti-aliased rendering, patterns, shadings, image data management, image creation, masking, and PDF document creation, display, and parsing.
