Seems almost too obvious to mention, but you could do something like:

Is such a thing possible with the PIL?

You didn't delete the periods that I put in to simulate indentations.

My understanding is that show() is mainly for debugging and tests, and that
it doesn't offer very much control or efficiency. That's not to say that
what you're after can't be done, maybe someone else can help you with that,
I just don't know.

When no filter is specified, does it use the Bilinear filter?

I'm wondering if there's some general rule as to when to use the Antialias
filter when resizing an image?
It seems that logo type images benefit greatly from it, but regular pictures
get less of a benefit?
I recently discovered that Atom-processor netbooks have a very hard time
with antialiasing,

Agreed, but the problem is I'm making a collage of pictures where the new
pictures are placed above previous pictures, so there's no one consistent
background color.

I'm wondering if anyone has any idea how to get better results from PIL's
rotate() function? No matter what filter I use I'm getting very jagged edges
after rotating an image.

pic = pic.rotate
I'm trying to take a group of pictures and give them rounded edges. I have a
source image (a rectangle with rounded edges, transparent PNG) and I'd like
to use this as a template. All the target images would become transparent
wherever this source image is transparent.

I have some "raw" images shot from a Canon DSLR that I'd like to manipulate
using the PIL. I know I can convert them using another program, but if
possible I'd like to do so directly using PIL.
Is this possible with the PIL?
Currently I get something like:
f = "IMG_0025.CR2"
im = Image.open(f)
Does anyone know if its possible to use Filter Factory (aka 8bf) files
in PIL, or any other way from Python or commandline? Apparently
there's a plugin for Gimp:

Python, of course! Just kidding, I don't know enough about Matlab to answer
that question well. Python's great for image processing though.
As far as your code, my guess is the output of split() when fed a gif isn't
in r g b format? Try running your code on a JPEG, works just fine. But with
a GIF
im = Image.open("whatever.jpg").convert('RGBA')

I don't know if the PIL has a way to preserve it, but if not you could
of course read the data before resizing then write the data to the new
image.
