[Mapserver-users] Image (PNG) not transparent in Netscape 6

[Bjoern Platzen]

Hi Steve,

now we made some tests on the images.
It seems as if the MapServer-image has two entries in the palette that 
are set to be transparent (Entries 0 and 1, both #ffffff). Maybe 
Netscape 6 isn't able to handle this.
Is this something that I could change in the mapfile or is this 
something that could only be changed in the MapServer-Sources?

I hope, that it is in the mapfile as I am not a C-Programmer...8~(

BTW: (I don't know if I mentioned) I'm working with MS 3.6.5 on a 
Linux-Box.

Bye, Bjoern.
