History[edit | edit source]
Steve Jobs, the co-founder of Apple who also founded NeXT, was an early adopter of Adobe PostScript, which was adapted into Display PostScript for the imaging technology of the NeXTSTEP operating system. However, Mac OS X (the successor to NeXTSTEP) replaced Display PostScript with PDF for its Quartz 2D framework to avoid licensing costs. Apple has since extended the use of PDF-based imaging to its Core Graphics framework, which is also used in its mobile operating systems, such as iOS and iPadOS.
Implementation[edit | edit source]
Quartz 2D is based on Adobe Systems' implementation of PDF 1.4. Graphics functions which don't require advanced features (such as graphics embedding) will fall back to PDF 1.3 for improved performance.
