Thanks! I was hoping that this would work for arbitrary graphics - including Text[] in various fonts. I will try it. My goal here is that I want to use Inset[] to compose various 2D and 3D graphics together. Nathan This message and any attachments, may contain confidential and/or legally privileged information.

The first depends on knowing precisely the structure of the Graphics object (not likely in practice). r1 = Graphics[Rectangle[{0, 0}, {1, 10}]]; r2 = Graphics[Rectangle[{0, 0}, {1, 2}]]; r1[[1, -1]] r2[[1, -1]] {1, 10} {1, 2} The second method doesn't have THAT flaw, but it could return coordinates from embedded rectangles OTHER than the one you want. (Depending on how you derived the object in the first place.) Cases[{r1, r2}, r_Rectangle :> Last@r, Infinity] {{1, 10}, {1, 2}} Bobby On Thu, 01 Jan 2009 19:29:08 -0600, Nathan Myhrvold <nathanm at intven.com> wrote: > Here is a simple question - is there a way to find out the aspect > ratio of a graphics object? > > So if I have > > r1 = Graphics[Rectangle[{0,0},{1,10}]] > r2 = Graphics[Rectangle[{0,0},{1,2}]] > > I want to recover {1,10} from r1, and {1,2} from r2. > > > Nathan > > This message and any attachments, may contain confidential and/or > legally privileged information.
