[Image-SIG] combining enhancers

[William Baxter]

Is there a way to combine the output of enhancers in PIL? I'd like 2
sliders for brightness and contrast to be used for the same image. But
if I try to use ImageEnhance.Brightness and ImageEnhance.Contrast on the
same image, they keep resetting, as if it's 2 separate images.

Thanks,
Bill B.
