ProviderAffine

All Implemented Interfaces:

Serializable, IdentifiedObject, OperationMethod

Enclosing class:

ProjectiveTransform

public static final class ProjectiveTransform.ProviderAffine
extends MathTransformProvider

The provider for the "Affine general parametric transformation" (EPSG 9624). The OGC's name is "Affine". The default matrix size is 3×3.

Note that affine transform is a special case of projective transform.

Constructor Detail

ProviderAffine

public ProviderAffine()

Creates a provider for affine transform with a default matrix size.

Method Detail

getOperationType

public Class<Conversion> getOperationType()

Returns the operation type.

Overrides:

getOperationType in class MathTransformProvider

Returns:

The GeoAPI interface implemented by this operation.

createMathTransform

protected MathTransform createMathTransform(ParameterValueGroup values)
                                     throws ParameterNotFoundException

Creates a projective transform from the specified group of parameter values.

Specified by:

createMathTransform in class MathTransformProvider

Parameters:

values - The group of parameter values.

Returns:

The created math transform.

Throws:

ParameterNotFoundException - if a required parameter was not found.

MathTransformProvider.Delegate

getProvider

public static ProjectiveTransform.ProviderAffine getProvider(int sourceDimensions,
                                                             int targetDimensions)

Returns the operation method for the specified source and target dimensions. This method provides different methods for different matrix sizes.

Parameters:

sourceDimensions - The number of source dimensions.

targetDimensions - The number of target dimensions.

Returns:

The provider for transforms of the given source and target dimensions.
