8.3. Type 1 Fonts
The Type 1 font standard was devised by Adobe, and Type 1 fonts are supported by Adobe's PostScript standard. Because of this, they are also well supported under linux. They are supported by X and ghostscript. Postscript fonts have traditionally been the choice of font for anything on UNIX that involves printing.
Typically, a UNIX Type 1 font is distributed as an afm (adobe font metric) file, and an outline file, which is usually a pfb ( printer font binary ) or pfa (printer font ascii) file. The outline file contains all the glyphs, while the metric file contains the metrics.
Type 1 fonts for other platforms may be distributed in different formats. For example, PostScript fonts for windows often use a different format ( pfm ) for the metric file.
