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

virtual void Ogre::ILImageCodec::code const DataChunk   input,
DataChunk   output,
...   
const [pure virtual]
 

Codes the data in the input chunk and saves the result in the output chunk.

Note:
Has a variable number of arguments, which depend on the codec type.

Implements Ogre::ImageCodec.

Implemented in Ogre::BMPCodec, Ogre::DDSCodec, Ogre::JPEGCodec, Ogre::PNGCodec, and Ogre::TGACodec.

void Ogre::ILImageCodec::codeToFile const DataChunk   input,
const String   outFileName,
CodecData *    pData
const [virtual]
 

Encodes data to a file.

Parameters:
input  Chunk containing data to write
outFileName  Filename to output to (extension implies type)
pData  ImageData pointer

Implements Ogre::ImageCodec.

Codec::CodecData * Ogre::ILImageCodec::decode const DataChunk   input,
DataChunk   output,
...   
const [virtual]
 

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

Remarks:
The returned CodecData pointer is a pointer to a class that holds information about the decoded buffer. For an image, this would be the size, the bitdepht, etc.
Note:
Has a variable number of arguments, which depend on the codec type.

Implements Ogre::ImageCodec.

Reimplemented in Ogre::BMPCodec, Ogre::DDSCodec, Ogre::JPEGCodec, and Ogre::TGACodec.

Codec * Ogre::Codec::getCodec const String   extension [static, inherited]
 

Gets the codec registered for the passed in file extension.

Definition at line 35 of file OgreCodec.cpp.

References Except, Ogre::Codec::ms_mapCodecs, and Ogre::String::toLowerCase().

virtual unsigned int Ogre::ILImageCodec::getILType void    const [pure virtual]
 

Implemented in Ogre::BMPCodec, Ogre::DDSCodec, Ogre::JPEGCodec, Ogre::PNGCodec, and Ogre::TGACodec.

Referenced by decode().

virtual String Ogre::ILImageCodec::getType   const [pure virtual]
 

Returns the type of the codec as a String.

Implements Ogre::ImageCodec.
