Field Detail

mask

protected GraphicsNode mask

The node who's outline specifies our mask.

filterRegion

protected Rectangle2D filterRegion

Region to which the mask applies

Constructor Detail

MaskRable8Bit

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

Method Detail

setSource

public void setSource(Filter src)

The source to be masked by the mask node.

Specified by:

setSource in interface Mask

Parameters:

src - The Image to be masked.

getSource

public Filter getSource()

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

Specified by:

getSource in interface Mask

Returns:

The image to mask

getFilterRegion

public Rectangle2D getFilterRegion()

The region to which this mask applies

Specified by:

getFilterRegion in interface Mask

setFilterRegion

public void setFilterRegion(Rectangle2D filterRegion)

Returns the filter region to which this mask applies

Specified by:

setFilterRegion in interface Mask

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.

Specified by:

setMaskNode in interface Mask

Parameters:

mask - The graphics node that defines the mask image.

getMaskNode

public GraphicsNode getMaskNode()

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

Specified by:

getMaskNode in interface Mask

Returns:

The graphics node that defines the mask image.

getBounds2D

public Rectangle2D getBounds2D()

Pass-through: returns the source's bounds

Specified by:

getBounds2D in interface Filter

Overrides:

getBounds2D in class AbstractRable

createRendering

public RenderedImage createRendering(RenderContext rc)

Specified by:

createRendering in interface RenderableImage
