NAME

       Font::TTF::Hdmx - Horizontal device metrics

DESCRIPTION

       The table consists of an hash of device metric tables indexed by the ppem for that subtable. Each subtable consists of an array of advance
       widths in pixels for each glyph at that ppem (horizontally).

INSTANCE VARIABLES

       Individual metrics are accessed using the following referencing:

	   $f->{'hdmx'}{$ppem}[$glyph_num]

       In addition there is one instance variable:

       Num Number of device tables.

   METHODS
   $t->read
       Reads the table into data structures

   $t->out($fh)
       Outputs the device metrics for this font

   $t->tables_do(&func)
       For each subtable it calls &sub($ref, $ppem)

   $t->XML_element($context, $depth, $key, $value)
       Outputs device metrics a little more tidily

BUGS

       None known

NAME

       Font::TTF::OldCmap - Character map table

       This module is deprecated

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.

       Due to the complexity of working with segmented arrays, most of the handling of such arrays is via methods rather than via instance
       variables.

       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).

INSTANCE VARIABLES

       The instance variables listed here are not preceeded by a space due to their emulating structural information in the font.

       Num Number of subtables in this table

       Tables
	   An array of subtables ([0..Num-1])

       Each subtables also has its own instance variables which are, again, not preceeded by a space.

       Platform
	   The platform number for this subtable

       Encoding
	   The encoding number for this subtable

       Format
	   Gives the stored format of this subtable

       Ver Gives the version (or language) information for this subtable

       val This points to a Font::TTF::Segarr which contains the content of the particular subtable.

METHODS

   $t->read
       Reads the cmap into memory. Format 4 subtables read the whole subtable and fill in the segmented array accordingly.

       Format 2 subtables are not read at all.

   $t->ms_lookup($uni)
       Given a Unicode value in the MS table (Platform 3, Encoding 1) locates that table and looks up the appropriate glyph number from it.

   $t->find_ms
       Finds the Microsoft Unicode table and sets the "mstable" instance variable to it if found. Returns the table it finds.

   $t->out($fh)
       Writes out a cmap table to a filehandle. If it has not been read, then just copies from input file to output

   @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.

BUGS

       o   No support for format 2 tables (MBCS)
