Detailed Description

encoding class for data-to-data jpeg compression

Constructor & Destructor Documentation

JPEGEncoder()

icl::io::JPEGEncoder::JPEGEncoder

(

int

quality = 90

)

constructor with given jpeg quality

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

~JPEGEncoder()

icl::io::JPEGEncoder::~JPEGEncoder

(

)

Destructor.

Member Function Documentation

encode()

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

setQuality()

void icl::io::JPEGEncoder::setQuality

(

int

quality

)

sets the compression quality level

writeToFile()

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
