matplotlib-devel Mailing List for matplotlib (Page 2)

Very nice addition Michael.

I note that the plt.colormap() line must have gotten lost. It's referred 
to but not there.
I'll add some ideas to John's list:

* Demonstrate the imsave() command.
* Rather than show 50 lines or so of array data, just show a few lines, 
but demonstrate what img.shape is before and after slicing out the B 
channel with img[:,:,0]
* It may be worth mentioning explicitly that img[:,:,0] will give you 
the blue channel for an RGB and an RGBA image.
* Demonstrate the "upper" and "lower" keywords where relevant.
* Add a pointer to the scipy.ndimage module
* Extend the examples with RGB and RGBA images.
* You might like to show how to recarrays and views on the individual 
colour channels. There are examples in the mailing list archives or 
maybe on the scipy website - I can't remember where.
* If you want to get more advanced, talk about higher bit depth images 
than 8 bits per channel.
* If you want to get even more advanced, show how to change the UI to 
probe the pixel value (I wish matplotlib did this by default).
