How do I reduce pixellation in low resolution digital images?

Outline fonts are collections of vector images of glyphs. Early vector fonts were used by vector monitors and vector plotters using their own internal fonts, usually with thin single strokes instead of thick outlined glyphs. The advent of desktop publishing brought the need for a universal standard to integrate the graphical user interface of the first Macintosh and laser printers. The term to describe the integration technology was WYSIWYG. The universal standard was (and still is) Adobe PostScript.
