A class to handle mosaics of one or more identically-sized images
(or `~lsst.afw.image.Mask` or `~lsst.afw.image.MaskedImage`)
Notes
-----
Note that this mosaic is a patchwork of the input images; if you want to
make a mosaic of a set images of the sky, you probably want to use the coadd code
Examples
--------
.. code-block:: py
m = Mosaic()
m.setGutter(5)
m.setBackground(10)
m.setMode("square") # the default; other options are "x" or "y"
mosaic = m.makeMosaic(im1, im2, im3) # build the mosaic
display = afwDisplay.getDisplay()
display.mtv(mosaic) # display it
m.drawLabels(["Label 1", "Label 2", "Label 3"], display) # label the panels
# alternative way to build a mosaic
images = [im1, im2, im3]
labels = ["Label 1", "Label 2", "Label 3"]
mosaic = m.makeMosaic(images)
display.mtv(mosaic)
m.drawLabels(labels, display)
# Yet another way to build a mosaic (no need to build the images/labels lists)
for i in range(len(images)):
m.append(images[i], labels[i])
# You may optionally include a colour, e.g. afwDisplay.YELLOW, as a third argument
mosaic = m.makeMosaic()
display.mtv(mosaic)
m.drawLabels(display=display)
Or simply:
.. code-block:: py
mosaic = m.makeMosaic(display=display)
You can return the (ix, iy)th (or nth) bounding box (in pixels) with `getBBox()`
