Constructor & Destructor Documentation

virtual Ogre::ImageCodec::~ImageCodec  )  [virtual]
 


Member Function Documentation

virtual DataStreamPtr Ogre::Codec::code MemoryDataStreamPtr input,
CodecDataPtr pData
const [pure virtual, inherited]
 

Codes the data in the input stream and saves the result in the output stream.

Implemented in Ogre::DDSCodec, Ogre::FreeImageCodec, and Ogre::ILImageCodec.

virtual void Ogre::Codec::codeToFile MemoryDataStreamPtr input,
const String outFileName,
CodecDataPtr pData
const [pure virtual, inherited]
 

Codes the data in the input chunk and saves the result in the output filename provided.

Provided for efficiency since coding to memory is progressive therefore memory required is unknown leading to reallocations.

Parameters:
input The input data
outFileName The filename to write to
pData Extra information to be passed to the codec (codec type specific)

Implemented in Ogre::DDSCodec, Ogre::FreeImageCodec, and Ogre::ILImageCodec.

virtual DecodeResult Ogre::Codec::decode DataStreamPtr input  )  const [pure virtual, inherited]
 

Codes the data from the input chunk into the output chunk.

Parameters:
input Stream containing the encoded data
Note:
Has a variable number of arguments, which depend on the codec type.

Implemented in Ogre::DDSCodec, Ogre::FreeImageCodec, and Ogre::ILImageCodec.

static Codec* Ogre::Codec::getCodec const String extension  )  [static, inherited]
 

Gets the codec registered for the passed in file extension.

static CodecIterator Ogre::Codec::getCodecIterator void   )  [static, inherited]
 

Gets the iterator for the registered codecs.

Definition at line 89 of file OgreCodec.h.

String Ogre::ImageCodec::getDataType  )  const [virtual]
 

Returns the type of the data that supported by this codec as a String.

Implements Ogre::Codec.

Definition at line 74 of file OgreImageCodec.h.

static StringVector Ogre::Codec::getExtensions void   )  [static, inherited]
 

Gets the file extension list for the registered codecs.

virtual String Ogre::Codec::getType  )  const [pure virtual, inherited]
 

Returns the type of the codec as a String.

Implemented in Ogre::DDSCodec, Ogre::FreeImageCodec, and Ogre::ILImageCodec.

static void Ogre::Codec::registerCodec Codec pCodec  )  [static, inherited]
 

Registers a new codec in the database.

Definition at line 76 of file OgreCodec.h.

static void Ogre::Codec::unRegisterCodec Codec pCodec  )  [static, inherited]
 

Unregisters a codec from the database.

Definition at line 83 of file OgreCodec.h.


Member Data Documentation

CodecList Ogre::Codec::ms_mapCodecs [static, protected, inherited]
 

A map that contains all the registered codecs.

Definition at line 55 of file OgreCodec.h.
