Member Function Documentation

encode()

DataStreamPtr Ogre::FreeImageCodec::encode ( const Any &  input ) const

overridevirtual

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

Reimplemented from Ogre::ImageCodec.

encodeToFile()

void Ogre::FreeImageCodec::encodeToFile ( const Any &  input, const String &  outFileName  ) const

overridevirtual

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 (codec type specific)
outFileName	The filename to write to

Reimplemented from Ogre::ImageCodec.

decode()

void Ogre::FreeImageCodec::decode ( const DataStreamPtr &  input, const Any &  output  ) const

overridevirtual

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

Parameters

input	Stream containing the encoded data
output	codec type specific result

Reimplemented from Ogre::ImageCodec.

getType()

String Ogre::FreeImageCodec::getType ( ) const

overridevirtual

Returns the type of the codec as a String.

Implements Ogre::Codec.

magicNumberToFileExt()

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

overridevirtual

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.

startup()

static _OgreFreeImageCodecExport void Ogre::FreeImageCodec::startup ( void  )

static

Static method to startup FreeImage and register the FreeImage codecs.

Referenced by Ogre::FreeImagePlugin::install().

shutdown()

static _OgreFreeImageCodecExport void Ogre::FreeImageCodec::shutdown ( void  )

static

Static method to shutdown FreeImage and unregister the FreeImage codecs.

Referenced by Ogre::FreeImagePlugin::uninstall().
