[mapserver-users] mapserver produces interlaced PNGs even if I configured the map to output noninterlaced PNGs

[Adrian Popa]

Hmm,
I did that, and kept the same query parameters and I get this error:

msPostMapParseOutputFormatSetup(): General error message. Unable to 
select IMAGETYPE `agg'.

So, it seems that imagetype is useful after all.
