A Rust implementation of the Ramer–Douglas-Peucker line simplification algorithm.
Also available from crates.io
The shared library exposes a FFI: simplify_linestring_ffi.
Call it with 2 arguments:
- A C-compatible struct containing the following:
- data: a void pointer to a 2D array of double-precision floats: [[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]]``
-len: asize_tdenoting the length of the array (i.e. 3, above)
- A precision parameter, double_precisionfloat. E.g.1.0`
The return type is the same struct as above, containing the simplified linestring coordinates.
Callers must call drop_float_array(), passing the returned struct in order to free the memory that the shared library has allocated. Failure to do so will result in memory leaks.
