PDF::API3::Compat::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. 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

$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)
Finds a Unicode table, giving preference to the MS one, and looks up the given Unicode codepoint in it to find the glyph id.

$t->find_ms
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.

$t->ms_enc
Returns the encoding of the microsoft table (0 => symbol, etc.). Returns undef if there is no Microsoft cmap.

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

$t->XML_element($context, $depth, $name, $val)
Outputs the elements of the cmap in XML. We only need to process val here

@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.

is_unicode($index)
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) Martin Hosken Martin_Hosken@sil.org. See PDF::API3::Compat::API2::Basic::TTF::Font for copyright and licensing.
