javax.media.jai.operator .BinarizeDescriptor

BinarizeDescriptor

public class BinarizeDescriptor extends OperationDescriptorImpl (Code)

An OperationDescriptor describing the "Binarize" operation.

The "Binarize" operation takes one rendered or renderable single-banded source image and a threshold value and applies a thresholding operation to the produce a bilevel image.

By default the destination image bounds are equal to those of the source image. The SampleModel of the destination image is an instance of MultiPixelPackedSampleModel.

The pseudocode for "Binarize" is as follows:

 
 dst(x, y) = src(x, y) >= threshold ? 1 : 0;

Resource List
Name Value

GlobalName Binarize

LocalName Binarize

Vendor com.sun.media.jai

Description Thresholds an image into a bilevel image.

Method Detail

create
public static RenderedOp create(RenderedImage source0, Double threshold, RenderingHints hints)(Code)
	Binarize an image from a threshold value. Creates a `ParameterBlockJAI` from all supplied arguments except `hints` and invokes JAI.create(StringParameterBlockRenderingHints) . See Also: JAI See Also: ParameterBlockJAI See Also: RenderedOp Parameters: source0 - `RenderedImage` source 0. Parameters: threshold - Argment must be of type java.lang.Double. Parameters: hints - The `RenderingHints` to use.May be `null`. The `RenderedOp` destination. throws: IllegalArgumentException - if `source0` is `null`. throws: IllegalArgumentException - if `threshold` is `null`.

createRenderable
public static RenderableOp createRenderable(RenderableImage source0, Double threshold, RenderingHints hints)(Code)
	Binarize an image from a threshold value. Creates a `ParameterBlockJAI` from all supplied arguments except `hints` and invokes JAI.createRenderable(StringParameterBlockRenderingHints) . See Also: JAI See Also: ParameterBlockJAI See Also: RenderableOp Parameters: source0 - `RenderableImage` source 0. Parameters: threshold - Argment must be of type java.lang.Double. Parameters: hints - The `RenderingHints` to use.May be `null`. The `RenderableOp` destination. throws: IllegalArgumentException - if `source0` is `null`. throws: IllegalArgumentException - if `threshold` is `null`.

validateSources
protected boolean validateSources(String modeName, ParameterBlock args, StringBuffer msg)(Code)
	Validates the input source. In addition to the standard checks performed by the superclass method, this method checks that the source image is single-banded.
