Hi Paul,
DDS as a file is not compressed. It has support for packed/compressed texel
formats but their file representation is the same as representaion in
graphic card memory. Besides packed pixel formats it supports almost all
pixel formats used these days (all supported by DirectX).
Unfortunately OSG DDS plugin supports only a subset of DDS capabitlities.
Looks like 32 bit FLOAT RGBA is supported on Read. Writing currently works
only with 8 bit components. It should be quite easy to add other pixel
formats, though.
Cheers,
Wojtek Lewandowski

FYI, DDS doesn't necessarily imply DXT compressed images. The DDS format
will handle uncompressed 32-bit floating point just fine. I think the
OSG DDS plugin also handles it.
Really? Does the OSG DDS plugin has some kind of option to turn
compression off?
