Mixed Content in PDF Files
Although PDF files can contain a mix of PostScript-based art, PostScript text, and
bitmapped graphics, each format has different scaling properties. PostScript-based art
and text scale smoothly, but bitmapped graphics embedded in a PDF file are subject to
the same scaling issues as other bitmapped graphics formats. As a result, bitmapped
graphics can soften if scaled larger than their original size.
