Constructor Detail

GradientBevelFilter

public GradientBevelFilter(GradientBevelFilter.Builder builder)

Create a GradientBevelFilter and initialize it wit the values defined in the Builder.

Parameters:

builder - a Builder object.

GradientBevelFilter

public GradientBevelFilter(SWFDecoder coder,
                           Context context)
                    throws IOException

Creates and initialises a GradientBevelFilter 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.

Method Detail

getGradients

public List<Gradient> getGradients()

Get the list of gradients used to create the glow colour.

Returns:

the list of Gradient objects.

getBlurX

public float getBlurX()

Get the blur amount in the x-direction.

Returns:

the horizontal blur amount.

getBlurY

public float getBlurY()

Get the blur amount in the y-direction.

Returns:

the vertical blur amount.

getAngle

public float getAngle()

Get the angle of the glow.

Returns:

the angle of the glow in radians.

getDistance

public float getDistance()

Get the distance of the glow from the object.

Returns:

the width of the glow.

getStrength

public float getStrength()

Get the strength of the glow.

Returns:

the glow strength.

getMode

public FilterMode getMode()

Get the compositing mode.

Returns:

the mode used for compositing, either TOP, INNER or KNOCKOUT.

getPasses

public int getPasses()

Get the number of passes for generating the blur.

Returns:

the number of blur passes.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object object)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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.
