[Mapserver-users] Just call me a newbie . . . multiple Raster [PNGs] LAYERs question

[Bob Basques]

Ok,

Now I'm trying to do the same with PNG files with little success.

The input tiles are PNG files with transparent alpha channel, like this one:

http://pwultra5.ci.stpaul.mn.us/cp_tiles/2002_property/L1T/570000_160000_1000_12_2002_SAINT_PAUL.PNG

with JPG tiles all I needed to add was the IMAGETYPE JPEG, and all was well.

With the PNG's nothing seems to work.

is there some special OUTPUTFORMAT that needs to be defined?  I would 
rather just pass the same file type through like the JPG's did.

Thanks
