exposureFromImage

lsst.obs.base.exposureFromImage(image, dataId=None, mapper=None, logger=None, setVisitInfo=True, setFilter=False, setExposureId=False)

Generate an Exposure from an image-like object

If the image is a DecoratedImage then also set its metadata (Image and MaskedImage are missing the necessary metadata and Exposure already has those set)

Parameters:

image : Image-like object

Can be one of lsst.afw.image.DecoratedImage, Image, MaskedImage or Exposure.

dataId : dict, optional

The data ID identifying the visit of the image.

mapper : lsst.obs.base.CameraMapper, optional

The mapper with which to convert the image.

logger : lsst.log.Log, optional

An existing logger to which to send output.

setVisitInfo : bool, optional

If True, create and attach a lsst.afw.image.VisitInfo to the result. Ignored if image is an Exposure with an existing VisitInfo.

setFilter : bool, optional

If True, create and attach a lsst.afw.image.FilterLabel to the result. Converts non-FilterLabel information provided in image. Ignored if image is an Exposure with existing filter information.

setExposureId : bool, optional

If True, create and set an exposure ID from dataID. Ignored if image is an Exposure with an existing ID.

Returns:

lsst.afw.image.Exposure

Exposure containing input image.
