The CID Menu
</H1>
<P>
The CID Menu provides a few commands for manipulating CID keyed fonts. If
the current font is a CID keyed font the menu also includes a list of all
subfonts that make up this one. This menu is only available in the font view.
<P>

<A HREF="#Convert">Convert to CID</A>

<A HREF="#Flatten">Flatten</A>
<LI>
<A HREF="#Insert">Insert Font</A>

<H2>
Er... What is a <A NAME="CID">CID</A> keyed Font?
</H2>
<P>
A CID keyed font is a postscript (or opentype) font designed to hold Chinese,
Japanese and Korean characters efficiently. More accurately a CID font is
a collection of several sub-fonts each with certain common features (one
might hold all the latin letters, another all the kana, a third all the kanji).
This allows font-wide hinting to be crafted for subsets of characters to
which have something in common.
<P>
CID keyed fonts do not have an encoding built into the font, and the characters
do not have names. Instead the font is associated with a character set and
on each character set there are several character mappings defined. These
mappings are similar to encodings but allow for a wider range of behaviors.
<P>
A CID is a character index and is used to look up glyph descriptions instead
of character names in other types of fonts. Using a character set PfaEdit
will often be able to map a CID to a unicode character name (but not always),
so PfaEdit will give characters names when it can.
<P>
For more information see the <A HREF="fontview.html#CID">section on CID keyed
fonts on the font view page</A>.
<P>
<DL>
<DT>
<A NAME="Convert">Convert to CID</A>
<DD>
If the current font is not a CID font then this command will convert it into
one containing one subfont (with the characters in this font). You will be
prompted for a character set.
<DT>
<A NAME="Flatten">Flatten</A>
<DD>
If the current font is a CID font then this command will convert it into
a normal font by taking all the characters from all the sub-fonts and merging
them into one normal font.
<DT>
<A NAME="Insert">Insert Font</A>
<DD>
Will allow you to browse for a normal font which will be added as another
sub font to the current CID font.
<DT>
<A NAME="Blank">Insert Blank</A>
<DD>
Inserts a blank sub-font into the current CID font.
<DT>
<A NAME="Remove">Remove</A> Font
<DD>
Removes the current font from the CID font. Anything in it will be lost.
(If you want to save it first then use Generate Font and save it as a pfb
file (or any other simple format).
<DT>
CID <A NAME="FontInfo">Font</A> Info
<DD>
This allows you to provide information on the entire collection of subfonts
rather than just the current subfont. It provides access to the standard
<A HREF="fontinfo.html">font info dialog</A>.
<HR>
<DT>
<sub font name>
<DD>
Clicking on a different sub font name in the menu will cause that sub-font
to be displayed instead of the current one.
