Image constants

    // resize contants
    const WIDTH   = 'width';
    const HEIGHT  = 'height';
    const AUTO    = 'auto';
    const INVERSE = 'inverse';
    const PRECISE = 'precise';
    const ADAPT   = 'adapt';
    const CROP    = 'crop';
    
    // Flipping constants 
    const HORIZONTAL = 'horizontal';
    const VERTICAL   = 'vertical';
