These are some of the things that are used within both the official PDF specs and Quartz: Quartz uses only some of the features of PDF, it is based on a subset of the full PDF specs. Since Quartz uses PDF, one would assume that everything that is possible within a PDF file is also supported by Quartz. This gives Apple considerably more flexibility with regard to what Quartz and the PDF interpreter can be used for.” Adobe PDF versus Quartz PDF Adobe just publishes a specification for how it’s supposed to function. Here is what an Apple employer had to say about this: “The Quartz renderer and the PDF interpreter that Apple ships with Mac OS X are built with Apple code, with no external licenses, by Apple employees. Some people have been wondering whether Apple pays licenses to Adobe for the technology used in Quartz. Even spool files sent to a printer are PDF data. Because Quartz uses the PDF drawing model for imaging, native applications can create and import PDFs without the need for outside programs. In short: Quartz implements a set of rules for describing how pictures and text are displayed and printed. automatic on-screen preview of graphics.a consistent feature set for all printers.Gone are the days when only the screen preview of EPS-files was printed on non-PostScript printers. The fact that Quartz can rasterize PDF files means that even cheap inkjet printers can output complex files. conversion of PDF data to raster data or PostScript.automatic PDF generation and save-as-PDF (disk and clipboard).Quartz performs a number of tasks that include include: Within QuickDraw, the native file format was PICT. Quartz replaces QuickDraw, which was used within earlier versions of MacOS. Alongside Quartz, OpenGL takes care of handling 3D data (used in games like Quake or Unreal as well as professional 3D applications like Maya) and QuickTime handles multimedia stuff (movies, sound,…). It is responsible for the rendering of all 2D objects. Quartz is a layer of software that runs on top of Darwin, the core (or kernel) of the Mac OS X operating system. OS X is the first operating system on the market that actually uses PDF technology within the operating system itself.
