PadRable8Bit

public PadRable8Bit(Filter src,
 Rectangle2D padRect,
 PadMode padMode)

Method Details

getSource

public Filter getSource()

Returns the source to be affine.

Specified by:

getSource in interface PadRable

setSource

public void setSource(Filter src)

Sets the source to be affine.

Specified by:

setSource in interface PadRable

Parameters:

src - image to affine.

getBounds2D

public Rectangle2D getBounds2D()

Description copied from interface: Filter

Returns the bounds of the current image. This should be 'in sync' with getMinX, getMinY, getWidth, getHeight

Specified by:

getBounds2D in interface Filter

Overrides:

getBounds2D in class AbstractRable

setPadRect

public void setPadRect(Rectangle2D rect)

Set the current rectangle for padding.

Specified by:

setPadRect in interface PadRable

Parameters:

rect - the new rectangle to use for pad.

getPadRect

public Rectangle2D getPadRect()

Get the current rectangle for padding

Specified by:

getPadRect in interface PadRable

Returns:

Rectangle currently in use for pad.

setPadMode

public void setPadMode(PadMode padMode)

Set the current extension mode for pad

Specified by:

setPadMode in interface PadRable

Parameters:

padMode - the new pad mode

getPadMode

public PadMode getPadMode()

Get the current extension mode for pad

Specified by:

getPadMode in interface PadRable

Returns:

Mode currently in use for pad

paintRable

public boolean paintRable(Graphics2D g2d)

Should perform the equivilent action as createRendering followed by drawing the RenderedImage to Graphics2D, or return false.

Specified by:

paintRable in interface PaintRable

Parameters:

g2d - The Graphics2D to draw to.

Returns:

true if the paint call succeeded, false if for some reason the paint failed (in which case a createRendering should be used).

createRendering

public RenderedImage createRendering(RenderContext rc)

Specified by:

createRendering in interface RenderableImage

getDependencyRegion

public Shape getDependencyRegion(int srcIndex,
 Rectangle2D outputRgn)

Description copied from interface: Filter

Returns the region of input data is is required to generate outputRgn.

Specified by:

getDependencyRegion in interface Filter

Overrides:

getDependencyRegion in class AbstractRable

Parameters:

srcIndex - The source to do the dependency calculation for.

outputRgn - The region of output you are interested in generating dependencies for. The is given in the user coordiate system for this node.

Returns:

The region of input required. This is in the user coordinate system for the source indicated by srcIndex.

getDirtyRegion

public Shape getDirtyRegion(int srcIndex,
 Rectangle2D inputRgn)

Description copied from interface: Filter

This calculates the region of output that is affected by a change in a region of input.

Specified by:

getDirtyRegion in interface Filter

Overrides:

getDirtyRegion in class AbstractRable

Parameters:

srcIndex - The input that inputRgn reflects changes in.

inputRgn - the region of input that has changed, used to calculate the returned shape. This is given in the user coordinate system of the source indicated by srcIndex.

Returns:

The region of output that would be invalid given a change to inputRgn of the source selected by srcIndex. this is in the user coordinate system of this node.
