NAME

PDF::API3::Compat::API2::Basic::TTF::Hdmx - Horizontal device metrics

CONTENTS

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

CW$t->read

Reads the table into data structures

CW$t->out($fh)

Outputs the device metrics for this font

CW$t->tables_do(&func)

For each subtable it calls &sub($ref, $ppem)

CW$t->XML_element($context, CW$depth, CW$key, CW$value)

Outputs device metrics a little more tidily

BUGS

None known
