Help with images

[Chad]

I have installed a TWAIN module(from
http://twainmodule.sourceforge.net) today and figured out how to
acquire an image. The only problem is that the image is way too large
in terms of filesize. It is over 1MB.

I can do either one of two things. Try to figure out how to manupilate
the image with this module(which I am been doing all day) or just use a
module that can compress jpegs. Can anybody help?

Check out PIL:

but also be sure to read the "Setting Capababilities" section of this
document:

Max,

I have read the document about setting the capabilities. I have also tried
the twexplore.exe to see the capabilities of my scanner. The twexplore.exe
will give you the option to save the file or "retrieve it natively." On the
window where it gives you this option, it also allows you to set attributes
like bit size, or compression. No matter how many times I change these
options, it still gives an image with the same filesize. The reason, I
mentioned that was because those attributes that you can change correlate to
the ICAP values. If changing those attributes in twexplore.exe does not do
anything, then I am thinking that it probably won't do anything when I write
a script either.

PIL does that.
