Methods Documentation

classmethod from_asdf(asdf_file)[source]

Create Transforms from AsdfFile

Parameters:: asdf_file (Stream-like or asdf.AsdfFile) – The asdf to create from.
Returns:: transforms – The Transforms instance.
Return type:: Transforms

to_asdf()[source]

Serialize to AsdfFile

Returns:: asdf_file – The ASDF serialization.
Return type:: asdf.AsdfFile

Notes

The override transforms are not serialized, since the values of this transform automatically represent what is in the override.

write_to_asdf(path)[source]

Serialize to a file path

Parameters:: path (Stream-like) –
