Abstract

This document describes the registration of the Multipurpose Internet Mail Extensions (MIME) sub-type application/font-tdpfr. The encoding is defined by the PFR Specification.

A Portable Font Resource (PFR) contains a set of glyph shapes. Each glyph shape is associated with a character code. The PFR format is designed to be both compact and platform-independent. It is intended to facilitate accurate rendering of fonts in all environments whether or not they have the required fonts already installed.

3.1 PFR Scope

A PFR contains a set of glyph shapes. Each glyph shape is associated with a character code. The PFR format is designed to be both compact and platform-independent. It is intended to facilitate accurate rendering of fonts in environments whether or not they have the required fonts already installed.

The glyph shape definitions in a PFR are resolution-independent. This allows glyph definitions to be displayed or printed on devices with a wide variety of resolutions. It also allows glyphs to be rendered at any size.

3.2 PFR Features

Some of the features of the PFR format are:

Compact representation of glyph shapes

Independent of byte order and operating system

Independent of output device resolution

Fully scalable to any glyph size

Optional inclusion of bitmap glyph images

Adopted as the font standard by DAVIC, DVB, and DTG
