[postgis-devel] Nice diagrams

[Obe, Regina]

Here is a silly thought.  Why don't we use image magick? It can support both postscript and svg.
http://www.imagemagick.org/Usage/draw/#svg
 
 I tried these simple commands on the svg file that Gustavo provided using my image magick install and got the attached results.  Of course to get the postscript, you need ghostscript installed which I'm not sure how hard that is on Linux.  The windows binary already has the svg driver compiled in and ghostscript is a simple install on windows.
 
convert drawing1.svg drawing1.png
convert drawing1.svg drawing1.eps
 
The other nice thing about using imagemagick is that we can come up with some jazzy effect like Kevin's that we can apply to all the images to make them look consistent  - e.g

Thanks,
Regina

Plain images will be best for web-based docs. It would be nice to have
vector sources, so that paper docs could have appropriately high
quality versions. Does inkscape save to postscript? (This is why I was
always so scared of doing images in the docs before... so many
options! :)
