That is possible, it depends on Nathan...I will be uploading the source
code, as soon as I finish a couple final touches.
Here is the current list of working post_process filters I have created:
clip_colors {COLOR}
Clips the colors in the image so none of the components exceed the
components in the given color.
invert
Inverts the image.
find_edges (syntax still in development)
The "cartoon-like" filter, finds the edges in the image and marks
them a specified color.
blur_matrix (syntax still in development)
Takes a matrix of values and applies it to each pixel in the image.
Hard to explain, but useful for blurring in specific ways.
color_matrix < AA, AB, AC,
BA, BB, BC,
CA, CB, CC>
Transforms the colors of the image with a 3*3 matrix.

This is looking pretty good. It might also pay to render the file with
a low color depth that used dithering to imitate a printing press's
halftoning? (This assumes you want a comic *book* appearance.)
Then again, how hard would it be to create an actual half-tone pattern
for an image?

Hey Chris,
This feature looks like it's got possibilities. If I gave you the code,
could you try doing this fella with your edging patch? I'd be interested to
see how it compares to the cumbersome process I used in Photoshop to make
the second image.

I would have to agree with Bob here, that I don't like lines around the
shadows. Leave it in, but allow us to control whether or not they have them.

Go ahead and e-mail me the code(or upload it to one of the groups here),
and I will try it out.

Still too cool. I can see all kinds of stuff
I would want to try this on. Can't wait for
the release.
