[mapguide-users] Help with SID files

[George McLean]

Hi Frank,

I am running from the command window as suggested. I created a new map 
in Studio with a large coordinate window to be sure I could see the 
image but I still can not see it. In the instructions I did not see a 
step to add specific files, only to specify the folder containing the 
sid files so I that is how I defined the resource.

When I load the web page containing the image layer, I get the following 
in the command window. Should I see more, like maybe a sid file loading?

GDAL: Auto Register C:\Program 
Files\MapGuideOpenSource\Server\Bin\gdalplugins\gdal_MrSID.dll using 
GDALRegister_MrSid.

Thanks again for your help.

George
