Drawing a frame

                 |CALL  IGFBOX (X1,X2,Y1,Y2,X3,X4,Y3,Y4) |
                 +--------------------------------------+
                                  
Action: This routine fills a frame according to the ``fill area colour index'' (see section [more info]), the ``fill area interior style'' (see section [more info]), and the ``fill area style index'' (see section [more info]) attributes. The border is never drawn unless the interior style is hollow or the routine IGSET has been called with 'BORD' and VAL = 1.. Like for the IGBOX primitive (see figure [more info]), the border of the frame is drawn according to the values of the ``line width scale factor'' (see section [more info]) and the ``polyline colour index'' (see section [more info]) attributes, whereas the ``line type'' is always solid (see section [more info]). Parameter Description:
X1
X coordinate of 1st corner of the outer rectangle in WC.
X2
X coordinate of 2nd corner of the outer rectangle in WC.
Y1
Y coordinate of 1st corner of the outer rectangle in WC.
Y2
Y coordinate of 2nd corner of the outer rectangle in WC.
X3
X coordinate of 1st corner of the inner rectangle in WC.
X4
X coordinate of 2nd corner of the inner rectangle in WC.
Y3
Y coordinate of 1st corner of the inner rectangle in WC.
Y4
Y coordinate of 2nd corner of the inner rectangle in WC.
