Detailed Description

encoding class for data-to-data jpeg compression

Constructor & Destructor Documentation

icl::io::JPEGEncoder::JPEGEncoder ( int  quality = 90)

constructor with given jpeg quality

The quality value is always given in percet (1-100)

icl::io::JPEGEncoder::~JPEGEncoder ( )

Destructor.

Member Function Documentation

const EncodedData& icl::io::JPEGEncoder::encode ( const core::ImgBase image)

encodes a given core::ImgBase * (only depth8u is supported natively)

non-depth8u images are automatically converted before compression. This might lead to loss of data

void icl::io::JPEGEncoder::setQuality ( int  quality)

sets the compression quality level

void icl::io::JPEGEncoder::writeToFile ( const core::ImgBase image,
const std::string &  filename 
)

first encodes the jpeg in memory and then write the whole memory chunk to disc
