Use the OFFSITE statement in the LAYER block for that image, as
described in the documentation.  If the pixels are true black, then
OFFSITE 0 0 0 will make them transparent.

Hi all

I am trying to display a bunch of RGB geotif. but the null padding
appears black. is there any way to make it transparent

To see the example go to:

http://letang.omg.unb.ca:8080/omg-map/omap.phtml

and in the "Quick View" drop-down menu please select "Passamaquoddy
Bay".

Thanks heaps

shoaib
