Page "Vector graphics" Paragraph 55

If we regard typographic characters as images, then the same considerations that we have made for graphics apply even to composition of written text for printing ( typesetting ).

Older character sets were stored as bitmaps, therefore to achieve maximum print quality they had to be used at a given resolution only ; these font formats are said to be non-scalable.

High quality typography is nowadays based on character drawings ( fonts ) which are typically stored as vector graphics, and as such are scalable to any size.

Examples of these vector formats for characters are Postscript fonts and TrueType fonts.
