NAME

Font::TTF::Head - The head table for a TTF Font

CONTENTS

DESCRIPTION

This is a very basic table with just instance variables as described in the TTF documentation, using the same names. One of the most commonly used is unitsPerEm.

INSTANCE VARIABLES

The head table has no internal instance variables beyond those common to all tables and those specified in the standard:



    version
    fontRevision
    checkSumAdjustment
    magicNumber
    flags
    unitsPerEm
    created
    modified
    xMin
    yMin
    xMax
    yMax
    macStyle
    lowestRecPPEM
    fontDirectionHint
    indexToLocFormat
    glyphDataFormat



The two dates are held as an array of two unsigned longs (32-bits)

METHODS

CW$t->read

Reads the table into memory thanks to some utility functions

CW$t->out($fh)

Writes the table to a file either from memory or by copying. If in memory (which is usually) the checkSumAdjustment field is set to 0 as per the default if the file checksum is not to be considered.

CW$t->minsize()

Returns the minimum size this table can be. If it is smaller than this, then the table must be bad and should be deleted or whatever.

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

Handles date process for the XML exporter

CW$t->update

Updates the head table based on the glyph data and the hmtx table

CW$t->getdate($is_create)

Converts font modification time (or creation time if $is_create is set) to a 32-bit integer as returned from time(). Returns undef if the value is out of range, either before the epoch or after the maximum storable time.

CW$t->setdate($time, CW$is_create)

Sets the time information for modification (or creation time if $is_create is set) according to the 32-bit time information.

BUGS
