/*! \brief class to plot an image from an 2-dimensional array of RGB values
    \ingroup jkqtplotter_imagelots_elements

    This class extends JKQTPMathImageBase and interprets the data array JKQTPMathImageBase::data as
    the 1st (RED) color channel and adds two more channels for GREEN and BLUE.

    Using setRgbMode() you can also use a different color system than RGB.
