java.awt.image.renderable
interface RenderedImageFactory
- All Known Subinterfaces:
- ContextualRenderedImageFactory
public interface RenderedImageFactory
The RenderedImageFactory interface (often abbreviated RIF) is
intended to be implemented by classes that wish to act as factories
to produce different renderings, for example by executing a series
of BufferedImageOps on a set of sources, depending on a specific
set of parameters, properties, and rendering hints.
Method Summary |
RenderedImage |
Creates a RenderedImage representing the results of an imaging
operation (or chain of operations) for a given ParameterBlock and
RenderingHints.
|
create
public RenderedImage create(ParameterBlock paramBlock,
RenderingHints hints)
-
Creates a RenderedImage representing the results of an imaging
operation (or chain of operations) for a given ParameterBlock and
RenderingHints. The RIF may also query any source images
referenced by the ParameterBlock for their dimensions,
SampleModels, properties, etc., as necessary.
The create() method can return null if the
RenderedImageFactory is not capable of producing output for the
given set of source images and parameters. For example, if a
RenderedImageFactory is only capable of performing a 3x3
convolution on single-banded image data, and the source image has
multiple bands or the convolution Kernel is 5x5, null should be
returned.
Hints should be taken into account, but can be ignored.
The created RenderedImage may have a property identified
by the String HINTS_OBSERVED to indicate which RenderingHints
were used to create the image. In addition any RenderedImages
that are obtained via the getSources() method on the created
RenderedImage may have such a property.
- Parameters:
paramBlock
- a ParameterBlock containing sources and parameters
for the RenderedImage to be created.
hints
- a RenderingHints object containing hints.
- Returns:
- A RenderedImage containing the desired output.
