[Image-SIG] copy pixels from one image to another

[august]

hello,

I'm sort of in a  hurry to do a simple operation, and am just now looking
at PIL to solve it.

Alls I want to do is take a very large image and chop it up into tiles of
smaller images (without having to copy the large image on every
operation - the original image is just large enough to fit in RAM).

However, I can't find any function in PIL that will allow my to copy
pixels.  Can this be?  There is no im.copyTo() function or something like
that.  I can use region = im.crop(bbox), but that actually crops the
original image.

any help on this one.  please respond to me directly as I am not on this
list.

thanks a million - august.
