Base class to map red, blue, green intensities into uint8 values Parameters ---------- minimum : `float` or sequence of `float` Intensity that should be mapped to black. If an array, has three elements for R, G, B. image The image to be used to calculate the mapping. If provided, also the default for makeRgbImage()

Convert 3 arrays, imageR, imageG, and imageB into a numpy RGB image imageR : `lsst.afw.image.Image` or `numpy.ndarray`, (Nx, Ny) Image to map to red (if `None`, use the image passed to the ctor) imageG : `lsst.afw.image.Image` or `numpy.ndarray`, (Nx, Ny), optional Image to map to green (if `None`, use imageR) imageB : `lsst.afw.image.Image` or `numpy.ndarray`, (Nx, Ny), optional Image to map to blue (if `None`, use imageR) xSize : `int`, optional Desired width of RGB image. If ``ySize`` is `None`, preserve aspect ratio ySize : `int`, optional Desired height of RGB image rescaleFactor : `float`, optional Make size of output image ``rescaleFactor*size`` of the input image
