ImageMagick is sloooow. Plus it has a ton of requirements before it will compile. GD2, on the other hand, is fast and lite. Also, if you know perl, there is GD::SVG http://search.cpan.org/~twh/GD-SVG-0.25/SVG.pm Once you have a GD object, you can easily convert to JPEG or PNG. and fairly simple to gain coordinates/bounds.
I wrote an imap module using GD2 for PNG images, so I know it is possible. It just might require more work than you had anticipated.
