Worldwind don't support local dds image?

[skyhorses]

Hi, everyone, I use Globle Mapper convert my high resolution satelite image to Worldwind Tiles in jpg format. saved in my local machine and load to WW, It works very well .

Then I change the tiles in every folder into dds format useing convim.exe, and I want to try if the load speed is faster than jpg. and I changed the <ImageFileExtension> tag in xml file to dds. But this time when I open the WW, no image loaded , Does anyone tell me whats wrong? TIA.

Are there any errors in WorldWind.log about something being wrong with the files (or anything like that)?

I think the xml file is ok, because I have two folders of tiles image, one is jpg format, the other is dds format,when I chage <PermanentDirectory> to jpg folder, open the WW, the image loads and appear. when I chage <PermanentDirectory> to dds folder, open the WW, nothing appear. And I preview the dds picture in Explorer, it shows no error.

Right-click the layer in the layer manager, click "Properties" and turn on the render file names option and zoom in on your layer. That will tell you whether it is looking in the right place for the tiles.
