aiSee: Export of Image Parts
When exporting graphs with aiSee 2, a combination of the four command line options
-xmin X1-ymin Y1-xmax X2-ymax Y2(X1,Y1)
and the lower right corner at (X2,Y2), the graph origin always
being at (0,0).
The corresponding command line option for aiSee 3 is
--area WxH+X+Y,
where W is the width of the image part and H its height,
while X and Y specify an offset from
the graph origin, i.e. from the upper left corner of the layout.
