 org.geotools.coverage.processing.operation.SelectSampleDimension
| SelectSampleDimension | | public class SelectSampleDimension extends Operation2D (Code) | | Chooses N
from a grid coverage and copies their sample data to the destination grid coverage in the order
specified. The
"SampleDimensions" parameter specifies the source
org.geotools.coverage.GridSampleDimension indices, and its size
(
SampleDimensions.length ) determines the number of sample dimensions of the destination
grid coverage. The destination coverage may have any number of sample dimensions, and a particular
sample dimension of the source coverage may be repeated in the destination coverage by specifying
it multiple times in the
"SampleDimensions" parameter.
Geotools extension:
This operation can also be used for selecting a different "visible sample dimension". Some
images may contain useful data in more than one sample dimension, but renderer the content
using only 1 sample dimension at time. The
"VisibleSampleDimension" parameter can be
used for selecting this sample dimension. If ommited, then the new grid coverage will inherit
its source's visible sample dimension.

"SelectSampleDimension" operation. |
| Method Summary | |
| public Coverage | doOperation(ParameterValueGroup parameters, Hints hints)
Applies the band select operation to a grid coverage. |
| SAMPLE_DIMENSIONS | | final public static ParameterDescriptor SAMPLE_DIMENSIONS(Code) | | The parameter descriptor for the sample dimension indices.
|
| VISIBLE_SAMPLE_DIMENSION | | final public static ParameterDescriptor VISIBLE_SAMPLE_DIMENSION(Code) | | The parameter descriptor for the visible dimension indice.

|
| SelectSampleDimension | | public SelectSampleDimension()(Code) | | Constructs a default
"SelectSampleDimension" operation.
|
| doOperation | | public Coverage doOperation(ParameterValueGroup parameters, Hints hints)(Code) | | Applies the band select operation to a grid coverage. This method is
invoked by
org.geotools.coverage.processing.DefaultProcessor for the
"SelectSampleDimension" operation.
Parameters:
parameters - List of name value pairs for the parameters.
Parameters:
hints - A set of rendering hints, or null if none. The result as a grid coverage. |
