Detailed Description

Codec specialized in loading ETC (Ericsson Texture Compression) images.

Remarks

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

Member Function Documentation

decode() [1/2]

DecodeResult Ogre::ETCCodec::decode ( const DataStreamPtr &  input ) const

overridevirtual

Deprecated:

Reimplemented from Ogre::Codec.

magicNumberToFileExt()

String Ogre::ETCCodec::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.

getType()

String Ogre::ETCCodec::getType ( ) const

overridevirtual

Returns the type of the codec as a String.

Implements Ogre::Codec.

startup()

static void Ogre::ETCCodec::startup ( void  )

static

Static method to startup and register the ETC codec.

shutdown()

static void Ogre::ETCCodec::shutdown ( void  )

static

Static method to shutdown and unregister the ETC codec.

decode() [2/2]

void Ogre::ImageCodec::decode
