PDF::API2::Basic::TTF::Cmap - Character map table
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.
$code
The instance variables listed here are not preceeded by a space due to their emulating structural information in the font.
Number of subtables in this table
An array of subtables ([0..Num-1])
Each subtables also has its own instance variables which are, again, not preceeded by a space.
The platform number for this subtable
The encoding number for this subtable
Gives the stored format of this subtable
Gives the version (or language) information for this subtable
A hash keyed by the codepoint value (not a string) storing the glyph id
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.
Finds a Unicode table, giving preference to the MS one, and looks up the given Unicode codepoint in it to find the glyph id.
Finds the a Unicode table, giving preference to the Microsoft one, and sets the mstable instance variable to it if found. Returns the table it finds.
mstable
Returns the encoding of the microsoft table (0 => symbol, etc.). Returns undef if there is no Microsoft cmap.
Writes out a cmap table to a filehandle. If it has not been read, then just copies from input file to output
Outputs the elements of the cmap in XML. We only need to process val here
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.
Returns whether the table of a given index is known to be a unicode table (as specified in the specifications)
No support for format 2 tables (MBCS)
