NAME ^

Font::TTF::Post - Holds the Postscript names for each glyph

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.

Looking up a glyph from a Postscript name or a name from a glyph number is achieved through methods rather than variable lookup.

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 MS.

The way to look up Postscript names or glyphs is:

    $pname = $f->{'post'}{'VAL'}[$gnum];
    $gnum = $f->{'post'}{'STRINGS'}{$pname};

INSTANCE VARIABLES ^

Due to different systems having different limitations, there are various class variables available to control what post table types can be written.

$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.

VAL

Contains an array indexed by glyph number of Postscript names. This is used when writing out a font.

STRINGS

An associative array of Postscript names mapping to the highest glyph with that name. These may not be in sync with VAL.

In addition there are the standard introductory variables defined in the standard:

    FormatType
    italicAngle
    underlinePosition
    underlineThickness
    isFixedPitch
    minMemType42
    maxMemType42
    minMemType1
    maxMemType1

METHODS ^

$t->read

Reads the Postscript table into memory from disk

$t->out($fh)

Writes out a new Postscript name table from memory or copies from disk

$t->XML_element($context, $depth, $key, $val)

Outputs the names as one block of XML

$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.
