17.8 Fonts
The next component of a WordprocessingML document is storing information about the fonts used in the document. WordprocessingML stores two pieces of information about fonts:
-
(optionally) Information about the font to enable font substitution. Font substitution is a process by
-
which an application, when it cannot locate a specific font, attempts to locate the closest possible match
-
to the intended appearance of the font
-
(optionally) One or more embedded forms of the font for use on systems which do not have access to
-
the font. When fonts are embedded, they are obfuscated to ensure that they are only used to view the
-
contents of the document in which they are embedded, and for no other purpose.
[Example: Consider the following information stored in a document’s font table part:
<w:fonts>
<w:font w:name="Times New Roman">
<w:panose1 w:val="02020603050405020304" />
<w:charset w:val="00" />
<w:family w:val="roman" />
<w:pitch w:val="variable" />
<w:sig w:usb0="20002A87" w:usb1="80000000" w:usb2="00000008"
w:usb3="00000000" w:csb0="000001FF" w:csb1="00000000" />
<w:embedRegular r:id="rId10" w:fontKey="{302EE813-EB4A-4642-A93A-
89EF99B2457E}" />
</w:font>
</w:fonts>The font table contains information about the Times New Roman font; specifically, information used to locate a substitute font when it is not available and a relationship to the embedded form of the regular form of the font. end example]
