get_transform_type

Context: transform

Synopsis

Return the flavor of the input Transform object.

Syntax

get_transform_type(transform)

The get_transform_type command returns a value indicating the flavor of the input Transform object. Transform types are 'Transform' (generic), 'WCSTAN', and 'LINEAR2D'. If the transform type is unknown, None is returned.

Example

>>> import pytransform
>>> cr = read_file("img.fits")
>>> trans = cr.get_transform("EQPOS")
>>> print(pytransform.get_transform_type(trans))
WCSTANTransform

Changes in CIAO 4.4

The pytransform module is no longer included as part of pycrates, so you either have to import it directly by saying

chips> import pytransform

or, if you have loaded pycrates as a named module, use the instance it provides:

>>> import pycrates as pyc

and then you can use pyc.apply_transform.
