std::pair< MemoryDataStreamPtr, CodecDataPtr > DecodeResult
Result of a decoding; both a decoded data stream and CodecData metadata.
Definition: OgreCodec.h:141
Codec specialized in loading ETC (Ericsson Texture Compression) images.
Definition: OgreETCCodec.h:47
static void startup(void)
Static method to startup and register the ETC codec.
virtual String getType() const
Returns the type of the codec as a String.
bool decodeKTX(DataStreamPtr &input, DecodeResult &result) const
static void shutdown(void)
Static method to shutdown and unregister the ETC codec.
void encodeToFile(MemoryDataStreamPtr &input, const String &outFileName, CodecDataPtr &pData) const
Codes the data in the input chunk and saves the result in the output filename provided.
ETCCodec(const String &type)
void flipEndian(void *pData, size_t size) const
static ETCCodec * msPKMInstance
Single registered codec instance.
Definition: OgreETCCodec.h:55
virtual ~ETCCodec()
Definition: OgreETCCodec.h:60
DataStreamPtr encode(MemoryDataStreamPtr &input, CodecDataPtr &pData) const
Codes the data in the input stream and saves the result in the output stream.

Definition: OgreETCCodec.h:56
String magicNumberToFileExt(const char *magicNumberPtr, size_t maxbytes) const
Maps a magic number header to a file extension, if this codec recognises it.
bool decodePKM(DataStreamPtr &input, DecodeResult &result) const
DecodeResult decode(DataStreamPtr &input) const
