PDF::API2::Basic::TTF::Table

PDF::API2::Basic::TTF::Table - Superclass for tables and used for tables we don't have a class for


NAME

PDF::API2::Basic::TTF::Table - Superclass for tables and used for tables we don't have a class for


DESCRIPTION

Looks after the purely table aspects of a TTF table, such as whether the table has been read before, locating the file pointer, etc. Also copies tables from input to output.


INSTANCE VARIABLES

Instance variables start with a space

read
Flag which indicates that the table has already been read from file.

dat
Allows the creation of unspecific tables. Data is simply output to any font file being created.

INFILE
The read file handle

OFFSET
Location of the file in the input file

LENGTH
Length in the input directory

CSUM
Checksum read from the input file's directory

PARENT
The the PDF::API2::Basic::TTF::Font manpage that table is part of


METHODS

PDF::API2::Basic::TTF::Table->new(%parms)

Creates a new table or subclass. Table instance variables are passed in at this point as an associative array.

$t->out($fh)

Writes out the table to the font file. If there is anything in the data instance variable then this is output, otherwise the data is copied from the input file to the output

$t->update

Each table knows how to update itself. This consists of doing whatever work is required to ensure that the memory version of the table is consistent and that other parameters in other tables have been updated accordingly. I.e. by the end of sending update to all the tables, the memory version of the font should be entirely consistent.

Some tables which do no work indicate to themselves the need to update themselves by setting isDirty above 1. This method resets that accordingly.


BUGS

No known bugs
