.SH "NAME"
Font::TTF::Post \- Holds the Postscript names for each glyph
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Holds the postscript names for glyphs. Note that they are not held as an
array, but as indexes into two lists. The first list is the standard Postscript
name list defined by the TrueType standard. The second comes from the font
directly.
.PP
Looking up a glyph from a Postscript name or a name from a glyph number is
achieved through methods rather than variable lookup.
.PP
This class handles PostScript table types of 1, 2, 2.5 & 3, but not version 4.
Support for version 2.5 is as per Apple spec rather than \s-1MS.\s0
.PP
The way to look up Postscript names or glyphs is:
.PP
.Vb 2
\&    $pname = $f\->{\*(Aqpost\*(Aq}{\*(AqVAL\*(Aq}[$gnum];
\&    $gnum = $f\->{\*(Aqpost\*(Aq}{\*(AqSTRINGS\*(Aq}{$pname};
.Ve
.SH "INSTANCE VARIABLES"
.IX Header "INSTANCE VARIABLES"
Due to different systems having different limitations, there are various class
variables available to control what post table types can be written.
.ie n .IP "$Font::TTF::Post::no25" 4
.el .IP "\f(CW$Font::TTF::Post::no25\fR" 4
.IX Item "$Font::TTF::Post::no25"
If set tells Font::TTF::Post::out to use table type 2 instead of 2.5 in case apps
cannot handle version 2.5.
.IP "\s-1VAL\s0" 4
.IX Item "VAL"
Contains an array indexed by glyph number of Postscript names. This is used when
writing out a font.
.IP "\s-1STRINGS\s0" 4
.IX Item "STRINGS"
An associative array of Postscript names mapping to the highest glyph with that
name. These may not be in sync with \s-1VAL.\s0
.PP
In addition there are the standard introductory variables defined in the
standard:
.PP
.Vb 9
\&    FormatType
\&    italicAngle
\&    underlinePosition
\&    underlineThickness
\&    isFixedPitch
\&    minMemType42
\&    maxMemType42
\&    minMemType1
\&    maxMemType1
.Ve
.SH "METHODS"
.IX Header "METHODS"
.ie n .SS "$t\->read"
.el .SS "\f(CW$t\fP\->read"
.IX Subsection "$t->read"
Reads the Postscript table into memory from disk
.ie n .SS "$t\->out($fh)"
.el .SS "\f(CW$t\fP\->out($fh)"
.IX Subsection "$t->out($fh)"
Writes out a new Postscript name table from memory or copies from disk
.ie n .SS "$t\->XML_element($context, $depth, $key, $val)"
.el .SS "\f(CW$t\fP\->XML_element($context, \f(CW$depth\fP, \f(CW$key\fP, \f(CW$val\fP)"
.IX Subsection "$t->XML_element($context, $depth, $key, $val)"
Outputs the names as one block of \s-1XML\s0
.ie n .SS "$t\->\fIminsize()\fP"
.el .SS "\f(CW$t\fP\->\fIminsize()\fP"
.IX Subsection "$t->minsize()"
Returns the minimum size this table can be. If it is smaller than this, then the table
must be bad and should be deleted or whatever.
.SH "BUGS"
