Detailed Description

Codec specialized in loading OITD (Ogre Internal Texture Dump) format.

Remarks

This format has two versions: Version 0 -> Used by Ogre 2.1 Version 1 -> Used by Ogre 2.2 The difference between the two are pixel format enums, and that Version 1 has rows aligned to 4 bytes, whereas Version 0 has no alignment restrictions. Version 0 is only used out of necessity, and is not generally recommended.

Member Function Documentation

decode()

virtual DecodeResult Ogre::OITDCodec::decode ( DataStreamPtr &  input ) const

virtual

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

Parameters

input

Stream containing the encoded data

Implements Ogre::Codec.

encode()

virtual DataStreamPtr Ogre::OITDCodec::encode ( MemoryDataStreamPtr &  input, CodecDataPtr &  pData  ) const

virtual

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

Implements Ogre::Codec.

encodeToFile()

virtual void Ogre::OITDCodec::encodeToFile ( MemoryDataStreamPtr &  input, const String &  outFileName, CodecDataPtr &  pData  ) const

virtual

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)

Implements Ogre::Codec.

getCodec() [1/2]

static Codec * Ogre::Codec::getCodec ( char *  magicNumberPtr, size_t  maxbytes  )

staticinherited

Gets the codec that can handle the given 'magic' identifier.

Parameters

magicNumberPtr	Pointer to a stream of bytes which should identify the file. Note that this may be more than needed - each codec may be looking for a different size magic number.
maxbytes	The number of bytes passed

getCodec() [2/2]

static Codec * Ogre::Codec::getCodec ( const String &  extension )

staticinherited

Gets the codec registered for the passed in file extension.

getCodecIterator()

static CodecIterator Ogre::Codec::getCodecIterator ( void  )

inlinestaticinherited

Gets the iterator for the registered codecs.

getDataType()

String Ogre::ImageCodec::getDataType ( ) const

inlinevirtualinherited

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

Implements Ogre::Codec.

getExtensions()

static StringVector Ogre::Codec::getExtensions ( void  )

staticinherited

Gets the file extension list for the registered codecs.

getType()

virtual String Ogre::OITDCodec::getType ( void  ) const

virtual

Returns the type of the codec as a String.

Implements Ogre::Codec.

isCodecRegistered()

static bool Ogre::Codec::isCodecRegistered ( const String &  codecType )

inlinestaticinherited

Return whether a codec is registered already.

magicNumberMatch()

virtual bool Ogre::Codec::magicNumberMatch ( const char *  magicNumberPtr, size_t  maxbytes  ) const

inlinevirtualinherited

Returns whether a magic number header matches this codec.

Parameters

magicNumberPtr	Pointer to a stream of bytes which should identify the file. Note that this may be more than needed - each codec may be looking for a different size magic number.
maxbytes	The number of bytes passed

magicNumberToFileExt()

virtual String Ogre::OITDCodec::magicNumberToFileExt ( const char *  magicNumberPtr, size_t  maxbytes  ) const

virtual

Maps a magic number header to a file extension, if this codec recognises it.

Parameters

magicNumberPtr	Pointer to a stream of bytes which should identify the file. Note that this may be more than needed - each codec may be looking for a different size magic number.
maxbytes	The number of bytes passed

Returns

A blank string if the magic number was unknown, or a file extension.

Implements Ogre::Codec.
