[Mapserver-users] Mr. SID to GeoTIFF

[bean@vt.edu]

I have aerial imagery in Mr. SID format and I use a LizardTech utility to 
convert the sid image to a geo tiff.  I can view the resulting tiff in an 
image viewer, however, when I load it in MapServer (via PHP), I get the 
following error:

[MapServer Error]: drawTIFF(): Only colormapped and grayscale images are 
supported.

More info:
