Class MaskRable8Bit

public class MaskRable8Bit extends AbstractRable implements Mask

MaskRable implementation

Field Summary
protected Rectangle2D	filterRegion Region to which the mask applies
protected GraphicsNode	mask The node who's outline specifies our mask.

Constructor Summary
	MaskRable8Bit(Filter src, GraphicsNode mask, Rectangle2D filterRegion)

Method Summary
RenderedImage	createRendering(RenderContext rc)
Rectangle2D	getBounds2D() Pass-through: returns the source's bounds
Rectangle2D	getFilterRegion() The region to which this mask applies
GraphicsNode	getMaskNode() Returns the Graphics node that the mask operation will use to define the masking image.
Filter	getSource() This returns the current image being masked by the mask node.
void	setFilterRegion(Rectangle2D filterRegion) Returns the filter region to which this mask applies
void	setMaskNode(GraphicsNode mask) Set the masking image to that described by gn.
void	setSource(Filter src) The source to be masked by the mask node.

Field Detail

filterRegion

protected Rectangle2D filterRegion

Region to which the mask applies

mask

protected GraphicsNode mask

The node who's outline specifies our mask.

Constructor Detail

MaskRable8Bit

public MaskRable8Bit(Filter src, GraphicsNode mask, Rectangle2D filterRegion)

Method Detail

createRendering

public RenderedImage createRendering(RenderContext rc)

getBounds2D

public Rectangle2D getBounds2D()

Pass-through: returns the source's bounds

getFilterRegion

public Rectangle2D getFilterRegion()

The region to which this mask applies

getMaskNode

public GraphicsNode getMaskNode()

Returns the Graphics node that the mask operation will use to define the masking image.

Returns: The graphics node that defines the mask image.

getSource

public Filter getSource()

This returns the current image being masked by the mask node.

Returns: The image to mask

setFilterRegion

public void setFilterRegion(Rectangle2D filterRegion)

Returns the filter region to which this mask applies

setMaskNode

public void setMaskNode(GraphicsNode mask)

Set the masking image to that described by gn. If gn is an rgba image then the alpha is premultiplied and then the rgb is converted to alpha via the standard feColorMatrix rgb to luminance conversion. In the case of an rgb only image, just the rgb to luminance conversion is performed.

Parameters: mask The graphics node that defines the mask image.

setSource

public void setSource(Filter src)

The source to be masked by the mask node.

Parameters: src The Image to be masked.
