.SH "NAME"
Font::TTF::OldCmap \- Character map table
.PP
This module is deprecated
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Looks after the character map. The primary structure used for handling a cmap
is the Font::TTF::Segarr which handles the segmented arrays of format 4 tables,
and in a simpler form for format 0 tables.
.PP
Due to the complexity of working with segmented arrays, most of the handling of
such arrays is via methods rather than via instance variables.
.PP
One important feature of a format 4 table is that it always contains a segment
with a final address of 0xFFFF. If you are creating a table from scratch this is
important (although Font::TTF::Segarr can work quite happily without it).
.SH "INSTANCE VARIABLES"
.IX Header "INSTANCE VARIABLES"
The instance variables listed here are not preceded by a space due to their
emulating structural information in the font.
.IP "Num" 4
.IX Item "Num"
Number of subtables in this table
.IP "Tables" 4
.IX Item "Tables"
An array of subtables ([0..Num\-1])
.PP
Each subtables also has its own instance variables which are, again, not
preceded by a space.
.IP "Platform" 4
.IX Item "Platform"
The platform number for this subtable
.IP "Encoding" 4
.IX Item "Encoding"
The encoding number for this subtable
.IP "Format" 4
.IX Item "Format"
Gives the stored format of this subtable
.IP "Ver" 4
.IX Item "Ver"
Gives the version (or language) information for this subtable
.IP "val" 4
.IX Item "val"
This points to a Font::TTF::Segarr which contains the content of the particular
subtable.
.SH "METHODS"
.IX Header "METHODS"
.ie n .SS "$t\->read"
.el .SS "\f(CW$t\fP\->read"
.IX Subsection "$t->read"
Reads the cmap into memory. Format 4 subtables read the whole subtable and
fill in the segmented array accordingly.
.PP
Format 2 subtables are not read at all.
.ie n .SS "$t\->ms_lookup($uni)"
.el .SS "\f(CW$t\fP\->ms_lookup($uni)"
.IX Subsection "$t->ms_lookup($uni)"
Given a Unicode value in the \s-1MS\s0 table (Platform 3, Encoding 1) locates that
table and looks up the appropriate glyph number from it.
.ie n .SS "$t\->find_ms"
.el .SS "\f(CW$t\fP\->find_ms"
.IX Subsection "$t->find_ms"
Finds the Microsoft Unicode table and sets the \f(CW\*(C`mstable\*(C'\fR instance variable
to it if found. Returns the table it finds.
.ie n .SS "$t\->out($fh)"
.el .SS "\f(CW$t\fP\->out($fh)"
.IX Subsection "$t->out($fh)"
Writes out a cmap table to a filehandle. If it has not been read, then
just copies from input file to output
.ie n .SS "@map = $t\->reverse([$num])"
.el .SS "\f(CW@map\fP = \f(CW$t\fP\->reverse([$num])"
.IX Subsection "@map = $t->reverse([$num])"
Returns a reverse map of the table of given number or the Microsoft
cmap. I.e. given a glyph gives the Unicode value for it.
.SH "BUGS"
.IX Header "BUGS"
