Hi,

Thanks for your answer Yewondwossen Assefa. I check my mapserv cgi and, yes it 
was built with OGR (INPUT=OGR). If I change/add the TRANSPARENCY parameter to 
60, all is working fine. 

Do you think I don't use the correct parameter ? The mapfile don't use OPACITY 
as valid parameter (except for the 5.0, and I am using the 4.10.1 release).

Y.
