Member Function Documentation

void PLJPEGEncoder::DoEncode (  PLBmp *  pBmp, PLDataSink *  pDataSink )  [protected, virtual]

Implements the actual encoding process. Uses variables local to the object to retrieve and store the data. Implemented in derived classes. Implements PLPicEncoder.

void PLJPEGEncoder::SetExifData (  PLExif &  ExifData  )

Set Exif (digital camera) Data for the next encode. The encoder only holds on to the Exif data until the next encode.
