Detailed Description

A class to retrieve synthetic images for display by the show* methods

Parameters
----------
isTrimmed : `bool`
    Should amps be trimmed?
verbose : `bool`
    Be chatty?
background : `float`
    The value of any pixels that lie outside the CCDs.
showAmpGain : `bool`
    Color the amp segments with the gain of the amp?
markSize : `float`
    Size of the side of the box used to mark the read corner.
markValue : `float`
    Value to assign the read corner mark.
ampImValue : `float` or `None`
    Value to assign to amps; scaleGain(gain) is used if `None`.
scaleGain : callable
    Function to scale the gain by.
