makeImageFromAmp¶
-
lsst.afw.cameraGeom.utils.makeImageFromAmp(amp, imValue=None, imageFactory=<class 'lsst.afw.image.image.image.ImageU'>, markSize=10, markValue=0, scaleGain=<function <lambda>>)¶ Make an image from an amp object.
Since images are integer images by default, the gain needs to be scaled to give enough dynamic range to see variation from amp to amp. The scaling algorithm is assignable.
Parameters: - amp :
lsst.afw.table.AmpInfoRecord Amp record to use for constructing the raw amp image.
- imValue :
floator None Value to assign to the constructed image, or scaleGain(gain) if None.
- imageFactory : callable like
lsst.afw.image.Image Type of image to construct.
- markSize :
float Size of mark at read corner in pixels.
- markValue :
float Value of pixels in the read corner mark.
- scaleGain : callable
The function by which to scale the gain (must take a single argument).
Returns: - ampImage :
lsst.afw.image An untrimmed amp image, of the type produced by
imageFactory.
- amp :
