[Image-SIG] ImageEnhance

[Jason C. Leach]

hi,

Ok. I got that working ok.  How can I do multiple enhancments?
Right now I:

enh = ImageEnhance.Contrast(im)
enh.enhance(1.15)

To increase the contrast by 15%, but I also need to modify the brightnes
and saturation.  In the code above I pass the obj to a Contrast
constructor; I'm not sure how to pass enh to a Brightnes() constructor or
get enh back into my 'im' (original image obj).

Thanks,
j.
