alpha-blending (image compositing) of arbitrary number of
monochromatic 2d images. Implements algorithms developed in Porter &
Duff (1984) and Smith
(1995). Image
cubes can be loaded from arrays, or FITS files, etc. Any valid pylab
color specification can be assigned to each image slice. The
individual alphas (values of opaqueness) for all slices will be
computed automatically such that each slice contributes 1/N to the
total image. The alphas can also be assigned manually (per-slice).
See also the extensive docstrings of classes Compositing, Image,
Cube, and in clumpyimage.py the class ClumpyImage, for
documentation.

An Ipython Notebook file is provided to see the classes in action. If you have Ipython notebook installed, launch
ipython notebook
A window in your browser should pop up. There, load the file
compositing.ipynb and play the cells. Alternatively, you can use the
online Ipython notebook viewer to play
the file.
compositing.md is a static Markdown view of the evaluated Ipython notebook.
IMG-AA00-TORUSG-sig15-i60-Y010-N01-q0.0-tv005.0.fits.gz is an
example FITS file used in the notebook. It's a
CLUMPY model, with nine 2d brightness maps
of torus emission at different wavelengths.
