assign(self: lsst.afw.detection.Footprint, arg0: lsst.afw.detection.Footprint) → lsst.afw.detection.Footprint¶

clipTo(self: lsst.afw.detection.Footprint, arg0: lsst.geom.Box2I) → None¶

computeFluxFromArray(image: ndarray, xy0: Point2I) → float¶

Calculate the total flux in the region of an image array contained in this Footprint.

Parameters:

image:: Array containing the pixels to extract.
xy0:: The origin of the image array.
Returns
flux:: Flux from the image in pixels contained in the footprint.

computeFluxFromImage(image: Image) → float¶

Calculate the total flux in the region of an Image contained in this Footprint.

Parameters:

image:: Image to extract.

Returns:

flux:: Flux from the image pixels contained in the footprint.

imageTypetype: This should be either a MaskedImage or Image and describes the type of the output image. If imageType is None then Image will be used.

Returns:
