PDF::API2::Basic::TTF::Cmap
Character map table

PDF::API2::Basic::TTF::Cmap - Character map table


NAME

PDF::API2::Basic::TTF::Cmap - Character map table


DESCRIPTION

Looks after the character map. For ease of use, the actual cmap is held in a hash against codepoint. Thus for a given table:


    $gid = $font->{'cmap'}{'Tables'}[0]{'val'}{$code};

Note that $code should be a true value (0x1234) rather than a string representation.


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
A hash keyed by the codepoint value (not a string) storing the glyph id


METHODS

@map = $t->reverse([$num])

Returns a reverse map of the table of given number or the Unicode cmap. I.e. given a glyph gives the Unicode value for it.


BUGS

  • No support for format 2 tables (MBCS)
