lsst.afw.display.rgb._rgbContinued.computeIntensity | ( | imageR, | |
imageG = None, | |||

Return a naive total intensity from the red, blue, and green intensities Parameters ---------- imageR : `lsst.afw.image.MaskedImage`, `lsst.afw.image.Image`, or `numpy.ndarray`, (Nx, Ny) intensity of image that'll be mapped to red; or intensity if imageG and imageB are None imageG : `lsst.afw.image.MaskedImage`, `lsst.afw.image.Image`, or `numpy.ndarray`, (Nx, Ny) intensity of image that'll be mapped to green; or None imageB : `lsst.afw.image.MaskedImage`, `lsst.afw.image.Image`, or `numpy.ndarray`, (Nx, Ny) intensity of image that'll be mapped to blue; or None Returns ------- image : type of ``imageR``, ``imageG``, and `imageB``

lsst.afw.display.rgb._rgbContinued.displayRGB | ( | rgb, | |
show = True ) |
Display an rgb image using matplotlib Parameters ---------- rgb The RGB image in question show : `bool` If `True`, call `matplotlib.pyplot.show()`

Make a set of three images into an RGB image using an asinh stretch and optionally write it to disk Parameters ---------- imageR imageG imageB minimum : `float` or sequence of `float` dataRange Q : `int` fileName : `str` The output file. The suffix defines the format, and must be supported by matplotlib saturatedBorderWidth If saturatedBorderWidth is non-zero, replace saturated pixels with ``saturatedPixelValue``. Note that replacing saturated pixels requires that the input images be `lsst.afw.image.MaskedImage`. saturatedPixelValue xSize ySize rescaleFactor

lsst.afw.display.rgb._rgbContinued.writeRGB | ( | fileName, | |
rgbImage ) |
Write an RGB image to disk Parameters ---------- fileName : `str` The output file. The suffix defines the format, and must be supported by matplotlib Most versions of matplotlib support png and pdf (although the eps/pdf/svg writers may be buggy, possibly due an interaction with useTeX=True in the matplotlib settings). If your matplotlib bundles pil/pillow you should also be able to write jpeg and tiff files. rgbImage The image, as made by e.g. makeRGB
