Font::TTF::Head(3pm) User Contributed Perl Documentation Font::TTF::Head(3pm) NAME
Font::TTF::Head - The head table for a TTF Font 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
$t->read Reads the table into memory thanks to some utility functions $t->out($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. $t->XML_element($context, $depth, $key, $value) Handles date process for the XML exporter $t->update Updates the head table based on the glyph data and the hmtx table $t->getdate($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. $t->setdate($time, $is_create) Sets the time information for modification (or creation time if $is_create is set) according to the 32-bit time information.
