NAME¶
mkeot - generate Embedded OpenType
SYNOPSIS¶
mkeot font-file [
URL [
URL ... ] ] >
EOT-file
DESCRIPTION¶
The
mkeot command writes an EOT (Embedded OpenType) file on standard
output that contains the given font file (OpenType or TrueType) and the given
URLs.
mkeot handles TrueType files, OpenType files with TrueType outlines, and
OpenType files with Postscript outlines. (Technically: all files with the
"sfnt" format.) However, Microsoft's Web browser
Internet
Explorer (version 8) cannot handle Postscript outlines. To use EOT files
with that browser, OpenType files with Postscript outlines must be converted
to TrueType files first. Several prgrams are able to do that, including the
free
fontforge.
The URLs that are added to the EOT file list the Web pages on which the EOT font
may be used. They act as prefixes, which means that, e.g., a URL such as
http://example.org/foo enables a font not only for that precise page, but also
for
http://example.org/foo2 or
http://example.org/foo/bar or any other pages
whose URL starts with the prefix.
The EOT specification allows EOT files without any URLs, but is not clear on the
meaning of such a file. In practice, at least in Microsoft's Internet Explorer
(version 8), an empty list of URLs means the font applies to no Web page at
all.
EOT font are typically used for Web pages. To that end, a link (URL) to the EOT
file must appear in the Web page's style sheet. A typical rule in CSS looks
like this:
@font-face {
font-family: My Fancy Font;
font-style: normal;
font-weight: normal;
src: url(http://example.org/fonts/fancy-roman.eot);
}
body {
font-family: My Fancy Font, serif;
}
This downloads the EOT file from the given URL and declares it to be a font of
normal weight and roman style with the family name "My Fancy Font."
That font can then be used in style rules, such as, in this example, to set
the font of body text. See the "CSS Fonts Module level 3" for
details on CSS.
TrueType files typically have the extension
.ttf, OpenType files
typically have the extension
.otf and EOT files typically end in
.eot.

BUGS¶
mkeot does not apply the optional MicroType Express compression.
mkeot may fail with fonts that have non-ASCII characters in their names.
mkeot cannot handle fonts that use (only) language tags instead of
traditional Microsoft/Apple language numbers in their names table. (Luckily,
this feature of OpenType version 1.6 appears to be little used.)
mkeot does not subset the font, unlike Microsoft's graphical WEFT tool.
To make a EOT file with a reduced set of glyphs, you must first create a
subsetted TrueType font with a font editor.
