# Glyph Bitmap Distribution Format (BDF) Specification

Read the BDF 2.2 specification for storing bitmap fonts, including global font information, glyph metrics, bitmap rows, and worked examples.

This is an unoffical web version of Adobe's official specification of Adobe™ Glyph Bitmap Distribution Format (BDF), Version 2.2, published on 22 March 1993.

I made the unoffical web version because it could be easier to read, search and link to than the PDF version. The original "Examples" chapiter has some errors, which I fixed.

An older version 2.1 of the BDF specification, and an unofficial BDF property list, are also included.

<Aside type="note">
Adobe holds the copyright of the BDF specification. You can find the original PDF file of the specification v2.2 — including the Copyright Notice and the Appendix — [here](https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5005.BDF_Spec.pdf), and the original PDF file of the specification v2.1 [here](https://www.x.org/docs/BDF/bdf.pdf).

The unoffical web version is not for profit, purely for educational purposes, and used within the scope of the "fair use" doctrine.
