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()`

lsst.afw.display.utils.Mosaic.append | ( | self, | |
image, | |||

Add an image to the list of images to be mosaiced Returns ------- index the index of this image (may be passed to `getBBox()`) Notes ----- Set may be cleared with ``Mosaic.reset()``

frame = None ) |
Draw the list labels at the corners of each panel. Notes ----- If labels is None, use the ones specified by ``Mosaic.append()``

lsst.afw.display.utils.Mosaic.getBBox | ( | self, | |
ix, | |||
iy = None ) |
Get the BBox for a panel Parameters ---------- ix : `int` If ``iy`` is not `None`, this is the x coordinate of the panel. If ``iy`` is `None`, this is the number of the panel. iy : `int`, optional The y coordinate of the panel.

Return a mosaic of all the images provided. If none are specified, use the list accumulated with `Mosaic.append()`. If display is specified, display the mosaic
