javax.media.jai.operator.XorConstDescriptor
| XorConstDescriptor | | public class XorConstDescriptor extends OperationDescriptorImpl (Code) | | An OperationDescriptor describing the "XorConst" operation.
The XorConst operation takes one rendered or renderable image
and an array of integer constants, and performs a bit-wise logical
"xor" between every pixel in the same band of the source and the
constant from the corresponding array entry. If the number of
constants supplied is less than the number of bands of the
destination, then the constant from entry 0 is applied to all the
bands. Otherwise, a constant from a different entry is applied to
each band.
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 "xor" operation.
Logical "xor"
| src | const | Result |
|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
The destination pixel values are defined by the pseudocode:
if (constants.length < dstNumBands) {
dst[x][y][b] = src[x][y][b] ^ constants[0];
} else {
dst[x][y][b] = src[x][y][b] ^ constants[b];
}

| validateArguments | | public boolean validateArguments(String modeName, ParameterBlock args, StringBuffer message)(Code) | | Validates the input source and parameter.
In addition to the standard checks performed by the
superclass method, this method checks that the source image has
an integral data type and that "constants" has length at least 1.
