Unable to load MrSid image with SDK v16.04

dcoggin

Mike,

I have upgraded to the version 16 SDK and I am unable to load a MrSid image. GM_LoadLayerList returns error 3 when attempting to load the image.

Thanks for looking into it.

David,

I took a look and found an issue loading SID files in v16 if the projection could not be automatically determined. I was seeing a prompt to fake position or cancel rather than just selecting the projection like the GM app had. This may have failed differently for you depending on your load flags.

I have placed a new SDK build with the latest changes at http://www.globalmapper.com/GlobalMapperSDK_v16_latest_beta.zip . Also make sure you are using the latest MrSID DLL files from the bin/bin64 folder. They have changed since SDK v15.

Thanks,

Mike,

I still have the problem with the new build. The same MrSID image loads fine in normal GM16 and GM16 automatically recognizes the projection.

I have lti_dsdk_9.1.dll in the bin64 folder. I believe that's the correct one. If it matters I also see lti_lidar_dsdk.dll and lti_lidar_dsdk_1.1.dll in the folder. Any other ideas?

Thanks,
David

David,

What flags are you passing to GM_LoadLayerList? Can you provide a sample SID file that doesn't load in the SDK? The SID files I have now all load fine for me with the latest SDK build. If you use the C++ sample application included with the SDK do they fail there too?

Note you don't need lti_lidar_dsdk.dll, that's from the old SDK. The lti_lidar_dsdk_1.1.dll should be all that is in the latest GM SDK builds. That shouldn't cause a problem, just an extra file you don't need.

Thanks,

Mike,

I am passing zero for the load flag argument. I checked the file string and it's good.

The 32-bit sample app works fine; the 64-bit sample app fails like my app (which is 64-bit). Hope that helps.

David,

Aha that was the clue I needed. The 32-bit was fine, but the 64-bit folder had the 32-bit DLLs instead of the 64-bit DLLs. I've fixed that now and the 64-bit version works. I have placed a new SDK build with the latest changes at http://www.globalmapper.com/GlobalMapperSDK_v16_latest_beta.zip .

Mike,

I still show the same problem. Was the 64-bit dll updated?

Thanks for the help,
David

David,

Yikes I apologize, WinZip didn't update the DLLs in the .zip file when I fixed them in the folder, I guess because the dates were older. I've manually updated that now and the SDK installer .exe on the web site is also updated. I have placed a new SDK build with the latest changes at http://www.globalmapper.com/GlobalMapperSDK_v16_latest_beta.zip .
