Class DefineShape2

java.lang.Object
  com.flagstone.transform.shape.DefineShape2

All Implemented Interfaces:

Copyable<MovieTag>, SWFEncodeable, DefineTag, MovieTag, ShapeTag

public final class DefineShape2
extends Object
implements ShapeTag

DefineShape2 defines a shape to be displayed with an extended set of fill styles. It extends the functionality of the DefineShape class by allowing more than 255 fill or line styles to be specified.

The shape defines a path containing a mix of straight and curved edges and pen move actions. A path need not be contiguous. When the shape is drawn the ShapeStyle object selects the line and fill styles, from the respective list, to be used. ShapeStyle objects can be defined in the shape at any time to change the styles being used. The fill style used can either be a solid colour, a bitmap image or a gradient. The line style specifies the colour and thickness of the line drawn around the shape outline. For both line and fill styles the selected style may be undefined, allowing the shape to be drawn without an outline or left unfilled.

Constructor Detail

DefineShape2

public DefineShape2(SWFDecoder coder,
                    Context context)
             throws IOException

Creates and initialises a DefineShape2 object using values encoded in the Flash binary format.

Parameters:

coder - an SWFDecoder object that contains the encoded Flash data.

context - a Context object used to manage the decoders for different type of object and to pass information on how objects are decoded.

Throws:

IOException - if an error occurs while decoding the data.

DefineShape2

public DefineShape2(int uid,

                    Shape aShape)

Creates a DefineShape2 object.

Parameters:

uid - the unique identifier for the shape in the range 1..65535.

rect - the bounding rectangle for the shape. Must not be null.

fills - the list of fill styles used in the shape. Must not be null.

lines - the list of line styles used in the shape. Must not be null.

aShape - the shape to be drawn. Must not be null.

DefineShape2

public DefineShape2(DefineShape2 object)

Creates and initialises a DefineShape2 object using the values copied from another DefineShape2 object.

Parameters:

object - a DefineShape2 object from which the values will be copied.

add

public DefineShape2 add(LineStyle style)

Add a LineStyle to the list of line styles.

Specified by:

Returns:

this object.

add

public DefineShape2 add(FillStyle style)

Add the fill style to the list of fill styles.

Specified by:

add in interface ShapeTag

Parameters:

style - and FillStyle object. Must not be null.

Returns:

this object.

getBounds

public Bounds getBounds()

prepareToEncode

public int prepareToEncode(Context context)

Prepare an object for encoding, returning the expected size of an object when it is encoded. This method also used to initialise variables, such as offsets and flags that will be used when the object is encoded. Generally the method returns the size in bytes, however when called on objects that use bit fields such as shapes the methods will return the size in bits.

Specified by:

prepareToEncode in interface SWFEncodeable

Parameters:

context - an Context that allows information to be passed between objects to control how they are initialised for encoding.

Returns:

the size of the object when it is encoded.

encode

public void encode(SWFEncoder coder,
                   Context context)
            throws IOException

Encode an object to the Flash binary format.

Specified by:

encode in interface SWFEncodeable

Parameters:

coder - an SWFEncoder object.

context - an Context that allows information to be passed between objects to control how they are initialised for encoding.

Throws:

IOException - if an error occurs while encoding the object.
