◆ assembleAmplifierImage()

def lsst.afw.cameraGeom.assembleImage.assembleAmplifierImage (   destImage,
  rawImage,
  amplifier 
)
Assemble the amplifier region of an image from a raw image.

Parameters
----------
destImage : `lsst.afw.image.Image` or `lsst.afw.image.MaskedImage`
    Assembled image; the region amplifier.getBBox() is overwritten with
    the assembled amplifier image.
rawImage : `lsst.afw.image.Image` or `lsst.afw.image.MaskedImage`
    Raw image (same type as destImage).
amplifier : `lsst.afw.cameraGeom.Amplifier`
    Amplifier geometry, with raw amplifier info.

Raises
------
RuntimeError
    Raised if image types do not match or amplifier has no raw amplifier info.

◆ assembleAmplifierRawImage()

def lsst.afw.cameraGeom.assembleImage.assembleAmplifierRawImage (   destImage,
  rawImage,
  amplifier 
)
Assemble the amplifier region of a raw CCD image.

For most cameras this is a no-op: the raw image already is an assembled
CCD image.
However, it is useful for camera such as LSST for which each amplifier
image is a separate image.

Parameters
----------
destImage : `lsst.afw.image.Image` or `lsst.afw.image.MaskedImage`
    CCD Image; the region amplifier.getRawAmplifier().getBBox()
    is overwritten with the raw amplifier image.
rawImage : `lsst.afw.image.Image` or `lsst.afw.image.MaskedImage`
    Raw image (same type as destImage).
amplifier : `lsst.afw.cameraGeom.Amplifier`
    Amplifier geometry with raw amplifier info

Raises
------
RuntimeError
    Raised if image types do not match or amplifier has no raw amplifier info.
