affine

public static <T extends net.imglib2.type.NativeType<T>> Function<BlockSupplier<T>,UnaryBlockOperator<T,T>> affine(net.imglib2.realtransform.AffineGet transformFromSource,
                                                                                                                   Transform.Interpolation interpolation)

Interpolate and affine-transform blocks of the standard ImgLib2 RealTypes.

Only 2D and 3D are supported currently!

The returned factory function creates an operator matching the type a given input BlockSupplier<T>.

Type Parameters:

T - the input/output type

Parameters:

transformFromSource - a 2D or 3D affine transform

interpolation - which interpolation method to use

Returns:

factory for UnaryBlockOperator to affine-transform blocks of type T

affine

Interpolate and affine-transform blocks of the standard ImgLib2 RealTypes.

Only 2D and 3D are supported currently!

The returned factory function creates an operator matching the type a given input BlockSupplier<T>.

Type Parameters:

T - the input/output type

Parameters:

transformFromSource - a 2D or 3D affine transform

interpolation - which interpolation method to use

computationType - For n-linear interpolation, this specifies in which precision intermediate values should be computed. For AUTO, the type that can represent the input/output type without loss of precision is picked. That is, FLOAT for u8, i8, u16, i16, i32, f32, and otherwise DOUBLE for u32, i64, f64. For nearest-neighbor interpolation, computationType is not used.

Returns:

factory for UnaryBlockOperator to affine-transform blocks of type T
