napari.utils.transforms.Transform#

class napari.utils.transforms.Transform(func=<function identity>, inverse=None, name=None)[source]#

Base transform class.

Defaults to the identity transform.

Parameters:

func (callable, Coords -> Coords) – A function converting an NxD array of coordinates to NxD’.
name (string) – A string name for the transform.

Methods

`compose`(transform)	Return the composite of this transform and the provided one.
`expand_dims`(axes)	Return a transform with added axes for non-visible dimensions.
`set_slice`(axes)	Return a transform subset to the visible dimensions.

Attributes

`changed`
`inverse`

Details

compose(transform: Transform) → Transform[source]#: Return the composite of this transform and the provided one.

Return a transform with added axes for non-visible dimensions.

Parameters:: axes (Sequence[int]) – Location of axes to expand the current transform with. Passing a list allows expansion to occur at specific locations and for expand_dims to be like an inverse to the set_slice method.
Returns:: Resulting transform.
Return type:: Transform

Return a transform subset to the visible dimensions.

Parameters:: axes (Sequence[int]) – Axes to subset the current transform with.
Returns:: Resulting transform.
Return type:: Transform
