C# Class Axiom.Media.DDSCodec

Codec specialized in loading DDS (Direct Draw Surface) images.

We implement our own codec here since we need to be able to keep DXT data compressed if the card supports it.

Inheritance: ImageCodec

Public Methods

Method	Description
Decode ( Stream input, Stream output ) : object	Codes the data from the input chunk into the output chunk.
Encode ( Stream input, Stream output ) : void	Encodes the data in the input stream and saves the result in the output stream.

MagicNumberToFileExt ( char magicNumber, UInt32 maxbytes ) : String
Shutdown ( ) : void
Startup ( ) : void
