You are right. I haven't been precise enough.
What I really need is some API or software library (preferably in C
or C++) that I could use to convert ESRI Arc/Info Grids (the binary
kind) to a Shapefile of polygons. If a library isn't available, a
command line utility that I can call from C/C++ would suffice.
I hope this clarify things a bit.
