Detailed Description

Codec specialized in images.

Remarks

The users implementing subclasses of ImageCodec are required to return a valid pointer to a ImageData class from the decode(...) function.

Member Function Documentation

decode() [1/2]

void Ogre::ImageCodec::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::Codec.

Reimplemented in Ogre::PVRTCCodec, and Ogre::STBIImageCodec.

Referenced by Ogre::EXRCodec::~EXRCodec().

encode() [1/2]

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

overridevirtual

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

Reimplemented from Ogre::Codec.

Reimplemented in Ogre::STBIImageCodec.

encodeToFile() [1/2]

void Ogre::ImageCodec::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::Codec.

Reimplemented in Ogre::STBIImageCodec.
