Detailed Description

Functor for writing a lti::image to a JPEG file To save a JPEG image just initialize the parameters of the "saveJPEG" object and call the apply member.

Example:

 lti::image anImg;                       // an image
 ...
 lti::saveJPEG saveImg;                  // the save functor
 lti::saveJPEG::parameters param;        // functor parameters
 param.filename = "~/tmp/theFile.jpeg";  // name of the JPEG file
 saveImg.setParameters(param);           // set the functor parameters
 saveImg.apply(anImg);                   // save the file

You can also use the more confortable shortcut:

 lti::image anImg;                       // an image
 ...
 lti::saveJPEG saveImg;                  // the save functor
 saveImg.save("~/tmp/theFile.jpeg",img); // save the image.
