Font formats

Most computer fonts used today are in bitmap or outline data formats. Bitmap fonts store fixed images for each glyph in each typeface and point size. Outline or vector fonts store glyphs as instructions for drawing each character's lines and curves. Outline fonts scaled smoothly in size over a wide range.

Common font filename extensions include:

Template:Codeline and Template:Codelinebitmap distribution format and gzip compressed Template:Codeline
Template:Codeline and Template:Codeline – bitmap portable compiled font and gzip compressed Template:Codeline
Template:Codeline and Template:Codeline – outline PostScript font ASCII and PostScript font binary. PostScript fonts carry built-in printer instructions.
Template:Codeline – outline TrueType font. Originally designed as a replacement for the PostScript fonts.
Template:Codeline – outline OpenType font. TrueType with PostScript typographic instructions.

Some Template:Codeline fonts are actually OpenType fonts and, for most purposes, the technical differences between TrueType and OpenType can be ignored. The OpenType format is published as the standard ISO/IEC 14496-22.

The typesetting application, TeX, and its companion font software, Metafont, render glyphs using their own methods. Some of the file extensions used for fonts by these two programs are Template:Codeline, Template:Codeline, Template:Codeline and Template:Codeline.
