Detailed Description

Codec specialized in loading PVRTC (PowerVR) images.

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

Member Function Documentation

DataStreamPtr Ogre::PVRTCCodec::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::PVRTCCodec::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.

DecodeResult Ogre::PVRTCCodec::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::PVRTCCodec::flipEndian	(	void *	pData,
		size_t	size,
		size_t	count
	)		const

protected

void Ogre::PVRTCCodec::flipEndian	(	void *	pData,
		size_t	size
	)		const

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

staticinherited

Gets the codec registered for the passed in file extension.

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

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

inlinestaticinherited

Gets the iterator for the registered codecs.

Definition at line 107 of file OgreCodec.h.

String Ogre::ImageCodec::getDataType ( ) const

inlinevirtualinherited

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 )

staticinherited

Gets the file extension list for the registered codecs.

virtual String Ogre::PVRTCCodec::getType ( ) const

virtual

Returns the type of the codec as a String.

Implements Ogre::Codec.

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

inlinestaticinherited

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

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

Definition at line 162 of file OgreCodec.h.

String Ogre::PVRTCCodec::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.
