This article describes the uncompressed bi-level image format that is usually called something like '''Bennet Yee's face format''', and sometimes '''YBM'''. It does not seem to have an official name. It is the format used by [[Netpbm]]'s ybmtopbm/pbmtoybm utilities, and is among the formats supported by the Fuzzy Pixmap library (<code>-B</code> option). It originated with utilities named "face" and "xbm", by Bennet Yee.

== Disambiguation ==
The name "Bennet Yee's face format" has also been used<ref>[http://ftp.andrew.cmu.edu/pub/AUIS/src/atk/image/faces.c faces.c]: Example of FaceSaver being called "Bennet Yee's face format"</ref> when referring to [[FaceSaver]], a completely different format. This may or may not be an error.

== Format ==
Files have a 6-byte header, followed by the image data.

== Identifiers ==
The Fuzzy Pixmap library suggests the file extension '''.bm'''.

== Identification ==
Files begin with <code>0x21 0x21</code> (ASCII "<code>!!</code>").

== Software ==
* [[Netpbm]]: pbmtoybm, ybmtopbm
* [http://www.ibiblio.org/pub/Linux/apps/graphics/convert/fbm-1.2.tgz fbm-1.2.tgz] - Fuzzy Pixmap Manipulation Library (see also [[FBM image]])

== Editors' notes ==
It would be nice to find copies of the "face" and "xbm" utilities. They are referenced in the man pages of old versions of Netpbm<ref>[http://www.manpager.com/linux/man1/pbmtoybm.1.html Old pbmtoybm man page]</ref>, which suggests that they were publicly available.
