NAME

SWF::Element - Classes of SWF tags and elements.

SYNOPSIS

use SWF::Element;
use SWF::BinStream;

$swf_stream=SWF::BinStream::Write;
....
$rect=SWF::Element::RECT->new;
$rect->configure(Xmin=>0, Ymin=>0, Xmax=>100, Ymax=>100);
$rect->pack($swf_stream);
....

DESCRIPTION

SWF::Element module handles SWF tags and any other sub elements to create, configure, clone, pack to bit strings, and unpack from bit strings.

SWF::Element::*

SWF::Element class is a base class of SWF element, such as Tag, RECT, SHAPE, etc. Each SWF::Element object has one or more fields.

METHODS

$element=SWF::Element::* ->new([parameters]);

creates a new element. The new element is configured with parameters.

$element->clone;

duplicates the element.

$element->configure( [name[=>value, ...]] );

gets and sets fields of the element.

When calling without any parameter, the method returns all field names and values of the element as hash.

When calling with a field name, the method returns the field value of the element.

When calling with one or more pair of name and value, the method sets the field of the element and returns the element itself. If value is an array reference, recursively configure the field element.

$element->defined;

returns whether $element is defined or not. The $element is NOT defined if all of its field are not defined.

$element->dumper([\&outputsub, $indent]);

dumps the element as a perl script which can re-create the element. It can take the subroutine reference and initial indent width for output. The subroutine is called with the script string and the indent width. In default, prints the script to the selected filehandle (usually STDOUT).

$element->pack($stream);

writes the element to $stream as bit string SWF format. $stream should be SWF::BinStream::Write object.

$element->unpack($stream);

reads the bit string data from $stream and unpack the element. $stream should be SWF::BinStream::Read object.

$element->FieldName([configure parameters...]);

Each field of $element can access by field name. When calling without parameter, it returns the field object or value. when calling with parameters, it calls configure method to set the field with the parameters and returns the field object or value.

$element->FlagName([value]);

Some fields are sets of flags. A flag is not an object but a simple scalar value, and is accessed by flag accessor method. When calling without value, it returns the flag value. When calilng with the value, it sets proper bit(s) of the Flags field with the value and returns the flag value.

SWF::Element::Scalar derivatives

SWF::Element::Scalar derivatives represent a scalar field which have their own pack/unpack method.

SWF::Element::STRING    - null-terminated string.
SWF::Element::PSTRING   - pascal type string (string with its length).
SWF::Element::ID        - 16bit ID of SWF characters (shapes, bitmaps, sounds, etc.)
SWF::Element::BinData   - Binary Data (described later).

METHODS

SWF::Element::Scalar inherits all methods of SWF::Element except any field/flag accessors. Here described the difference.

$scalar->configure([value]): When calling without any parameter, the method returns the value of the object. When calling with a value, the method sets the value to the object and returns the value.
$scalar->value: returns the value of the object.

SWF::Element::BinData

represents a binary data.

METHODS

It has the same methods as SWF::Element::Scalar. The other methods are described here.

$bindata->Length: returns the length of the data.
$bindata->add( string ): adds a string to the data.
$bindata->substr( offset [, length , [replace]] ): Extracts a substring out of the data. It behaves similar to CORE::substr.
$bindata->save( file ): saves the data to the file. It takes a file name or a file handle.
$bindata->load( file ): loads the data from the file. It takes a file name or a file handle.

SWF::Element::Array::*

SWF::Element::Array is a base class which represents an array of the SWF element. The SWF::Element::Array object is an array reference.

METHODS

SWF::Element::Array has all methods of SWF::Element except any field/flag accessors. Here described the difference.

$array->configure( list... ): adds list to the array. Each element of the list must be a proper element object or an array reference.
$array->new_element: creates a proper new element for the array. The new element is not add the array automatically. You should do 'push @$array, $new' if you want to add the new element.

SUBCLASSES

Here is the list of all subclasses representing the SWF element. 'SWF::Element::' is omitted from each class name. ex. RECT means SWF::Element::RECT class. '$' represents a simple scalar. See 'Macromedia Flash (SWF) File Format Specifications' for further information about SWF elements and fields. You can get the document from http://www.macromedia.com/software/flash/open/licensing/fileformat/ .
