Detailed Description

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

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

Member Function Documentation

DataStreamPtr Ogre::DDSCodec::code	(	MemoryDataStreamPtr &	input,
		CodecDataPtr &	pData
	)			const `[virtual]`

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

Implements Ogre::Codec.

void Ogre::DDSCodec::codeToFile	(	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.

PixelFormat Ogre::DDSCodec::convertFourCCFormat ( uint32 fourcc ) const [private]

PixelFormat Ogre::DDSCodec::convertPixelFormat	(	uint32	rgbBits,
		uint32	rMask,
		uint32	gMask,
		uint32	bMask,
		uint32	aMask
	)			const `[private]`

DecodeResult Ogre::DDSCodec::decode ( DataStreamPtr & input ) const [virtual]

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.

Implements Ogre::Codec.

void Ogre::DDSCodec::flipEndian	(	void *	pData,
		size_t	size
	)			const `[private]`

void Ogre::DDSCodec::flipEndian	(	void *	pData,
		size_t	size,
		size_t	count
	)			const `[private]`

static Codec* Ogre::Codec::getCodec	(	char *	magicNumberPtr,
		size_t	maxbytes
	)			`[static, inherited]`

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

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 107 of file OgreCodec.h.

String Ogre::ImageCodec::getDataType ( ) const [virtual, inherited]

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

Implements Ogre::Codec.

Definition at line 79 of file OgreImageCodec.h.

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

Gets the file extension list for the registered codecs.

virtual String Ogre::DDSCodec::getType ( ) const [virtual]

Returns the type of the codec as a String.

Implements Ogre::Codec.

static bool Ogre::Codec::isCodecRegistered ( const String & codecType ) [static, inherited]

Return whether a codec is registered already.

Definition at line 94 of file OgreCodec.h.

virtual bool Ogre::Codec::magicNumberMatch	(	const char *	magicNumberPtr,
		size_t	maxbytes
	)			const `[virtual, inherited]`

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

Definition at line 162 of file OgreCodec.h.

String Ogre::DDSCodec::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.
