napari.utils.transforms.ScaleTranslate#

class napari.utils.transforms.ScaleTranslate(scale=(1.0,), translate=(0.0,), *, name=None)[source]#

n-dimensional scale and translation (shift) class.

Scaling is always applied before translation.

Parameters:

scale (1-D array) – A 1-D array of factors to scale each axis by. Scale is broadcast to 1 in leading dimensions, so that, for example, a scale of [4, 18, 34] in 3D can be used as a scale of [1, 4, 18, 34] in 4D without modification. An empty translation vector implies no scaling.
translate (1-D array) – A 1-D array of factors to shift each axis by. Translation is broadcast to 0 in leading dimensions, so that, for example, a translation of [4, 18, 34] in 3D can be used as a translation of [0, 4, 18, 34] in 4D without modification. An empty translation vector implies no translation.
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`	Return the inverse transform.

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
