| minimum | |
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

| def lsst.afw.display.rgb._rgbContinued.Mapping.mapIntensityToUint8 | ( | self, | |
| intensity | |||
| ) |
Map an intensity into the range of a uint8, [0, 255] (but not converted to uint8)
