Tim/Chris,

So for the GIS/GDAL suggestion are you talking about exporting the lines once I've used another technique to highlight the edges? Or will the Raster 2 Vector functions also help with the edge detection.

or the GDAL command line utilities.


Another option is to look at drawing programs -- InkScape has something 
that would probably work.
