A mapping for an asinh stretch (preserving colours independent of brightness) x = asinh(Q (I - minimum)/range)/Q Notes ----- This reduces to a linear stretch if Q == 0 See http://adsabs.harvard.edu/abs/2004PASP..116..133L

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

def lsst.afw.display.rgb._rgbContinued.AsinhMapping.mapIntensityToUint8 | ( | self, | |
intensity | |||
) |
Return an array which, when multiplied by an image, returns that image mapped to the range of a uint8, [0, 255] (but not converted to uint8) The intensity is assumed to have had minimum subtracted (as that can be done per-band)
Reimplemented from lsst.afw.display.rgb._rgbContinued.Mapping.
