The geocvpf library provides a set of GObject APIs to allow plotting of Vector Product Format (VPF) onto the GeocCanvas widget. The API set allows for customization of thematic and view objects through the GObject property interface. A database object allows for fast hash table lookups with large library sets. A library selector object narrows library selection based on the present canvas viewport.
