ImagingDDSLoadedMipMapCount 

Value of this option is number of mipmap levels of last loaded DDS image. 

ImagingDDSLoadedVolume 

Value of this option is non-zero if last loaded DDS file was volume texture. 

ImagingDDSSaveCubeMap 

If it is non-zero next saved DDS file should be stored as cube map. 

ImagingDDSSaveDepth 

Sets the depth (slices of volume texture or faces of cube map) of the next saved DDS file. 

ImagingDDSSaveMipMapCount 

Sets the number of mipmaps which should be stored in the next saved DDS file. 

ImagingDDSSaveVolume 

If it is non-zero next saved DDS file should be stored as volume texture. 

ImagingGIFLoadAnimated 

Boolean option that specifies whether GIF images with more frames are animated by Imaging (according to frame disposal methods) or just raw frames are loaded and sent to user (if you want to animate GIF yourself).
