Constructor Detail

MouldArrayImpl

public MouldArrayImpl(NDArray nda,
                      NDShape shape)

Creates a new ArrayImpl which which uses the pixels from an underlying NDArray moulded into a different shape (origin/dimensions). The number of pixels must be the same in the base NDArray and the requested new shape.

Parameters:

nda - the base NDArray which will supply the pixels

shape - the shape which this NDArray is to have

Throws:

IllegalArgumentException - if shape is does not have the same number of pixels as the shape of nda
