getName
Description copied from class:AbstractOperation
Returns the name of the processing operation. The default implementation returns the AbstractOperation.descriptor code name.- Specified by:
getName
in interfaceOperation
- Overrides:
getName
in classAbstractOperation
- Returns:
- The name of the processing operation.
-
deriveRange
protected NumberRange<? extends Number> deriveRange(NumberRange<? extends Number>[] ranges, OperationJAI.Parameters parameters) Returns the expected range of values for the resulting image.- Overrides:
deriveRange
in classOperationJAI
- Parameters:
ranges
- The range of values from every sources. For unary operations this array has a length of 1. For binary operations like"add"
and"multiply"
, this array has a length of 2.parameters
- Parameters, rendering hints and coordinate reference system to use.- Returns:
- The range of values to use in the destination image, or
null
if unknow.
-
handleJAIEXTParams
Description copied from class:OperationJAI
Extension point for adding to the JAIParameterBlockJAI
object the parameters defined in theParameterValueGroup
, which can be read by the JAI-EXT operations.Notice that if you are using JAI, the new parameters will not be accepted by the
ParameterBlockJAI
instance.- Overrides:
handleJAIEXTParams
in classOperationJAI
- Parameters:
parameters
-ParameterBlockJAI
instance used by the current JAI-EXT/JAI operationparameters2
-ParameterValueGroup
instance containing input operation parameters
-
getProperties
protected Map<String,?> getProperties(RenderedImage data, CoordinateReferenceSystem crs, InternationalString name, MathTransform gridToCRS, GridCoverage2D[] sources, OperationJAI.Parameters parameters) Description copied from class:OperationJAI
Prepares the properties to be given to the coverage created by thederiveGridCoverage
method. The default implementation returnsnull
.- Overrides:
getProperties
in classOperationJAI
- Parameters:
data
- TheRenderedImage
created by this operation.crs
- The coordinate reference system assigned to the coverage thisOperationJAI
will produce.name
- The name assigned to the coverage thisOperationJAI
will produce.gridToCRS
- The transform from grid tocrs
to be assigned to the coverage thisOperationJAI
will produce.sources
- The sources to be assigned to the coverage thisOperationJAI
will produce.parameters
- The parameters that were used by thisOperationJAI
.- Returns:
- a
Map
with the properties generated by thisOperationJAI
or null if we haven't any.
