# high_level_objects_to_values

astropy.wcs.wcsapi.high_level_objects_to_values(*world_objects, low_level_wcs)

  Convert the input high level object to low level values.

  This function uses the information in `low_level_wcs.world_axis_object_classes` and `low_level_wcs.world_axis_object_components` to convert the high level objects (such as `SkyCoord`) to low level “values” which should be scalars or Numpy arrays.

  This is used in `HighLevelWCSMixin.world_to_pixel`, but provided as a separate function for use in other places where needed.

  Parameters:
    *world_objects `SkyCoord`, `Quantity`, etc.

      High level coordinate objects.

    low_level_wcs `BaseLowLevelWCS` or `object`

      Source of the world axis metadata to use for the conversion. A full `BaseLowLevelWCS` instance is accepted, but any object exposing `world_axis_object_classes` and `world_axis_object_components` attributes also works (for example a `types.SimpleNamespace` or a namedtuple). The `serialized_classes` attribute is read if present and otherwise treated as `False`. This is useful when the metadata for the intended conversion direction does not match what a WCS exposes by default.
