Crate polylabel

This crate provides a Rust implementation of the Polylabel algorithm for finding the optimum position of a polygon label.

ffi bindings are provided: enable the ffi and headers features when building the crate.

Modules

• errors
  Errors that can occur when determining an optimum label position

Structs

• Array
  Wrapper for a void pointer to a sequence of 2-element arrays representing points, and the sequence length. Used for FFI.
• Position
  FFI struct for returned optimum Polygon label position
• WrapperArray
  Wrapper for a void pointer to a sequence of Arrays, and the sequence length. Used for FFI.

Functions

• polylabel
  Calculate a Polygon’s ideal label position by calculating its ✨pole of inaccessibility✨
• polylabel_ffi
  FFI access to the polylabel function
