[richard.greenwood@…]

MapServer (from FWTools 0.9.9 windows binary distribution) displays the
following error when attempting to dispaly a MrSID file:

msDrawMap(): Image handling error. Failed to draw layer named 'color2004'.
MrSIDRasterBand::IRasterIO(): Failed to load image. mg2 somethi: Unable to
access file. GDALRasterIO() failed: drawGDAL() 

For this sid file, gdalinfo reports:

The sid file can be downloaded from:
   http://inside.uidaho.edu/asp/NAIP2004.asp
I was using "Fremnot County" (400MB) but I encountered the same error with
"Teton County" (100MB) which is also available from the URI above.

I was able to display this sid file about a year ago in the mapserver/gdal
version at that time, however performance was very slow.

I attempted to display the sid file in OpenEV, FWTools version 0.9.9. I let it
run for about 2 hours, in which time it had displayed about 1/2 of the image.

Do not hesitate to contact me if there is additional information or help that I
can provide.

Thanks,
Rich

My first efforts to reproduce this on Linux with Mapserver on
~/data/mrsid/cen1.sid failed.  I could zoom in and out to any degree without 
any errors.  Performance was a bit eratic (from about 1s to about 3s) but 
seemed to settle down when the portion of the image was paged into the disk 
cache. 

I am downloading Teton county and will try again, moving to win32 and FWTools
if I can't reproduce it on linux.

Rich ... could you confirm the exact version of the MrSID DLLs you
used? 

[richard.greenwood@…]

DLL version info:

In FWTools0.9.9\bin:
  gdal_fw.dll 1.3.0.0b1, FWTools 0.9.9
  lti_dsdk_dll.dll 5.0.6.955
In FWTools0.9.9\plugins\mrsid\bin
  lti_dsdk_cdll.dll
  lti_dsdk_dll.dll
Neither of these files have version info in their properties, but intrernally I
found a string: "SDK Version 4.0.10.720.Bob_713_br" for whatever that's worth.

Rich,

Are you still having trouble with these MrSID files with the latest SDK that's in either MS4W or FWTools?
