image transparency

[Stephen Lime]

Yup, use the OFFSITE parameter. It takes as a value the color (index value) you
wish to be transparent. So, OFFSITE 0 makes color 0 in the image transparent and
so on.

No, there is no way to do any image pre-processing at the moment.

MapServer users,
Is there a way to specify a pixel value for transparency?  I have images 
with null value borders and would like the images to appear seamless so I 
would like to specify 0 0 0 or perhaps 255 255 255 as transparent.  BTW is 
there any way to tweak contrast/brightness?
Thank you.
