public class NotDescriptor

extends OperationDescriptorImpl

An OperationDescriptor describing the "Not" operation.

The Not operation takes one rendered or renderable image, and performs bit-wise logical "not" on every pixel from every band of the source image. No additional parameters are required.

The source image must have an integral data type. By default, the destination image bound, data type, and number of bands are the same as the source image.

The following matrix defines the logical "not" operation.

Logical "not"

src	Result
1	0
0	1

The destination pixel values are defined by the pseudocode:

 dst[x][y][b] = ~src[x][y][b];

Method Detail

validateSources

protected boolean validateSources(String modeName,
                                  ParameterBlock args,
                                  StringBuffer msg)

Validates the input source.

In addition to the standard checks performed by the superclass method, this method checks that the source image is of integral data type.

Overrides:

validateSources in class OperationDescriptorImpl

Tags copied from class: OperationDescriptorImpl

Parameters:

modeName - the operation mode name

args - a ParameterBlock that has the sources

msg - A string that may contain error messages.

Throws:

IllegalArgumentException - if any of the input parameters are null.
