The AffineTransform class

class nipy.labs.datasets.transforms.affine_transform.AffineTransform(input_space, output_space, affine)¶

A transformation from an input 3D space to an output 3D space defined by an affine matrix.

It is defined by the affine matrix , and the name of the input and output spaces.

__init__(input_space, output_space, affine)¶

Create a new affine transform object.

Parameters:

input_space: string: Name of the input space
output_space: string: Name of the output space
affine: 4x4 ndarray: Affine matrix giving the coordinate mapping between the input and output space.

composed_with(transform)¶

Returns a new transform obtained by composing this transform with the one provided.

Parameters:

transform: nipy.core.transforms.transform object: The transform to compose with.

inverse_mapping(x, y, z)¶

Transform the given coordinate from output space to input space.

Parameters:

mapping(x, y, z)¶

Transform the given coordinate from input space to output space.

Parameters:
