Hi List,
I'have the same question posted by Ben Brehmer in the late 2008, but
nobody have given a response until now.
I've been trying to get 24 bit PNG symbols to be transparent.
I've tried both GD and AGG output. I've tried --with-experimental-png.
I've tried editing the symbol in photoshop to be transparent.
Basically fooled around with all the different output format options.
I've tried both RGB and RGBA png images.
8 bit PNG symbols work just fine. But the 24 bit symbols always have a
white and non-transparent background (see attached image).
Is there any other mapfile configurations I can try before I convert
all of my 24 bit images to 8 bit?
Or maybe this is a known bug?
Thanks,
Dave
