AffineRable8Bit

public AffineRable8Bit(Filter src,
 AffineTransform affine)

Method Details

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

getSource

public Filter getSource()

Returns the source to be affine.

Specified by:

getSource in interface AffineRable

setSource

public void setSource(Filter src)

Sets the source to be affine.

Specified by:

setSource in interface AffineRable

Parameters:

src - image to affine.

setAffine

public void setAffine(AffineTransform affine)

Set the affine transform.

Specified by:

setAffine in interface AffineRable

Parameters:

affine - the new Affine transform to apply.

getAffine

public AffineTransform getAffine()

Get the Affine.

Specified by:

getAffine in interface AffineRable

Returns:

the Affine transform currently in effect.

paintRable

public boolean paintRable(Graphics2D g2d)

Should perform the equivilent action as createRendering followed by drawing the RenderedImage.

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.
