Method Details

create

public RenderedImage create(ParameterBlock paramBlock,
 RenderingHints renderHints)

Creates a new instance of ScaleOpImage in the rendered layer. This method satisfies the implementation of RIF.

Specified by:

create in interface RenderedImageFactory

Specified by:

create in class CRIFImpl

Parameters:

paramBlock - The source image, the X and Y scale factor, and the interpolation method for resampling.

create

public RenderedImage create(RenderContext renderContext,
 ParameterBlock paramBlock)

Creates a new instance of AffineOpImage in the renderable layer. This method satisfies the implementation of CRIF.

Specified by:

create in interface ContextualRenderedImageFactory

Overrides:

create in class CRIFImpl

Parameters:

renderContext - The rendering information associated with this rendering.

paramBlock - The parameters used to create the image.

Returns:

A RenderedImage.

mapRenderContext

public RenderContext mapRenderContext(int i,
 RenderContext renderContext,
 ParameterBlock paramBlock,
 RenderableImage image)

Maps the output RenderContext into the RenderContext for the ith source. This method satisfies the implementation of CRIF.

Specified by:

mapRenderContext in interface ContextualRenderedImageFactory

Overrides:

mapRenderContext in class CRIFImpl

Parameters:

i - The index of the source image.

renderContext - The renderContext being applied to the operation.

paramBlock - The ParameterBlock containing the sources and the translation factors.

image - The RenderableImageOp from which this method was called.

Returns:

The RenderContext to be used to render the given source.

getBounds2D

public Rectangle2D getBounds2D(ParameterBlock paramBlock)

Gets the bounding box for the output of ScaleOpImage. This method satisfies the implementation of CRIF.

Specified by:

getBounds2D in interface ContextualRenderedImageFactory

Overrides:

getBounds2D in class CRIFImpl

Parameters:

paramBlock - A ParameterBlock containing the sources and parameters of the operation.

Returns:

A Rectangle2D specifying the bounding box.
