 org.geotools.referencing.operation.transform.PassThroughTransform
| PassThroughTransform | | public class PassThroughTransform extends AbstractMathTransform implements Serializable(Code) | | Transform which passes through a subset of ordinates to another transform.
This allows transforms to operate on a subset of ordinates. For example,
if you have (latitude,longitude,height)
coordinates, then you may wish to convert the height values from feet to
meters without affecting the latitude and longitude values.

Parameters:
firstAffectedOrdinate - Index of the first affected ordinate.

| create | | public static MathTransform create(int firstAffectedOrdinate, MathTransform subTransform, int numTrailingOrdinates)(Code) | | Creates a transform which passes through a subset of ordinates to another transform.
This allows transforms to operate on a subset of ordinates. For example, if you have
(latitidue,longitude,height) coordinates, then you
may wish to convert the height values from feet to meters without affecting the
latitude and longitude values.
Parameters:
firstAffectedOrdinate - Index of the first affected ordinate.
Parameters:
subTransform - The sub transform.
Parameters:
numTrailingOrdinates - Number of trailing ordinates to pass through.Affected ordinates will range from firstAffectedOrdinate inclusive to dimTarget-numTrailingOrdinates exclusive. A pass through transform with the following dimensions:
Source: firstAffectedOrdinate + subTransform.getSourceDimensions() + numTrailingOrdinatesTarget: firstAffectedOrdinate + subTransform.getTargetDimensions() + numTrailingOrdinates |
