//Create a new true color image. The return value is an image identifier. The background defaults to black. Parameters (x_size*y_size)
$red = imagecolorallocate($ing,255,0,0);//Define background color
$yellow = imagecolorallocate($ing,237,231,32);//Define yellow
imagefill($ing,0,0,$red);//Fill color, starting from coordinates (0,0)
//Array coordinates, representing (x1,y1,x2,y2,x3,y3....x11,y11);
$a = array(90,30,108,73,157,73,119,102,135,152,93,123,52,152,66,102,29,74,76,73,90,30);
imagefilledpolygon($ing,$a,10,$yellow);//Draw a polygon: 10 represents the total number of vertices, $yellow represents the filling color
$a1 = array(229,25,229,43,248,48,229,55,229,74,217,60,198,66,210,50,197,34,218,39,229,25);
imagefilledpolygon($ing,$a1,10,$yellow);
$a2 = array(227,108,227,127,245,134,228,139,227,157,215,143,196,149,208,132,196,117,215,122,227,108);
