/**
 * Options class for ezcImageHandler->save() methods.
 * 
 * @property int $compression
 *           The compression level to use, if compression is supported by the
 *           target format (e.g. TIFF). A value between 0 and 9 (incl.) is
 *           expected.
 * @property int $quality A quality indicator used to determine the quality of
 *           the target image, if supported by the target format (e.g. JPEG). A
 *           value between 0 and 100 (incl.) is expected.
 * @property array(int) $transparencyReplacementColor
 *           Only certain image formats support transparent backgrounds (e.g.
 *           GIF and PNG). If such images are converted to a format that does
 *           not support transparency, this color will be used as the new
 *           background. The color value is given as an array of integers, each
 *           representing a color value in RGB between 0 and 255.
 *           <code>array( 255, 0, 0 )</code> for example would be pure red.
