[mapserver-users] Average/Bilinear Resampling and Alpha Bands

[Jason Beverage]

Hi all,

I have some imagery that is in UTM that contains an alpha band that
masks out areas with no data.  When I use MapServer to reproject it to
epsg:4326, the masked out area looks good if I set RESAMPLE=NEAREST on
the layer.  If I change the RESAMPLE option to BILINEAR or AVERAGE I
get black splotches in the area that is transparent.

Has anyone else seen this behavior?

I'm using MapServer 5.6.1

Thanks,

Jason
