javax.media.jai.operator.BandSelectDescriptor
| BandSelectDescriptor | | public class BandSelectDescriptor extends OperationDescriptorImpl (Code) | | An OperationDescriptor describing the "BandSelect" operation.
The BandSelect operation chooses N bands from a
rendered or renderable source image and copies the pixel data of
these bands to the destination image in the order specified. The
bandIndices parameter specifies the source band
indices, and its size (bandIndices.length) determines
the number of bands of the destination image. The destination
image may have ay number of bands, and a particular band of the
source image may be repeated in the destination image by specifying
it multiple times in the bandIndices parameter.
Each of the bandIndices value should be a valid
band index number of the source image. For example, if the source
only has two bands, then 1 is a valid band index, but 3 is not. The
first band is numbered 0.
The destination pixel values are defined by the pseudocode:
dst[x][y][b] = src[x][y][bandIndices[b]];

| BandSelectDescriptor | | public BandSelectDescriptor()(Code) | | Constructor.
|
| validateArguments | | public boolean validateArguments(String modeName, ParameterBlock args, StringBuffer message)(Code) | | Validates the input source and parameters.
In addition to the standard checks performed by the
superclass method, this method checks that "bandIndices" has a
length of at least 1 and does not contain any values less than
0 or greater than the number of source bands minus 1.
