PDF::API2::Basic::TTF::Loca

PDF::API2::Basic::TTF::Loca - the Locations table, which is intimately tied to the glyf table


NAME

PDF::API2::Basic::TTF::Loca - the Locations table, which is intimately tied to the glyf table


DESCRIPTION

The location table holds the directory of locations of each glyph within the glyf table. Due to this relationship and the unimportance of the actual locations when it comes to holding glyphs in memory, reading the location table results in the creation of glyph objects for each glyph and stores them here. So if you are looking for glyphs, don't look in the glyf table, look here instead.

Things get complicated if you try to change the glyph list within the one table. The recommendation is to create another clean location object to replace this table in the font, ensuring that the old table is read first and to transfer or copy glyphs across from the read table to the new table.


INSTANCE VARIABLES

The instance variables do not start with a space

glyphs
An array of glyph objects for each glyph.

glyphtype
A string containing the class name to create for each new glyph. If empty, defaults to the PDF::API2::Basic::TTF::Glyph manpage.


METHODS

$t->read

Reads the location table creating glyph objects (the PDF::API2::Basic::TTF::Glyph manpage) for each glyph allowing their later reading.


BUGS

None known
