- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class ConjugateDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "Conjugate" operation.
The Conjugate operation negates the imaginary components of
pixel values of a rendered or renderable source image containing
complex data. The source image must contain an even number of
bands with the even-indexed bands (0, 2, ...) representing the
real and the odd-indexed bands (1, 3, ...) the imaginary parts of
each pixel. The destination image similarly contains an even
number of bands with the same interpretation and with contents
defined by:
dst[x][y][2*k] = src[x][y][2*k];
dst[x][y][2*k+1] = -src[x][y][2*k+1];
where the index k varies from zero to one less than the number
of complex components in the destination image.
"Conjugate" defines a PropertyGenerator that sets the "COMPLEX"
property of the image to java.lang.Boolean.TRUE, which may
be retrieved by calling the getProperty() method with
"COMPLEX" as the property name.

ConjugateDescriptor
public ConjugateDescriptor()
- Constructor.
getPropertyGenerators
public PropertyGenerator[] getPropertyGenerators(String modeName)
- Returns an array of
PropertyGenerators implementing
property inheritance for the "Conjugate" operation.
- Overrides:
- getPropertyGenerators in class OperationDescriptorImpl
- Returns:
- An array of property generators.
validateSources
protected boolean validateSources(String modeName,
ParameterBlock args,
StringBuffer msg)
- Validates the input sources.
In addition to the standard checks performed by the
superclass method, this method checks that the source image
has an even number of bands.
- Overrides:
- validateSources in class OperationDescriptorImpl
- Tags copied from class: OperationDescriptorImpl
- Parameters:
modeName - the operation mode nameargs - a ParameterBlock that has the sourcesmsg - A string that may contain error messages.- Throws:
- IllegalArgumentException - if any of the input parameters are
null. - See Also:
OperationDescriptorImpl.validateArguments(java.lang.String, java.awt.image.renderable.ParameterBlock, java.lang.StringBuffer)
