Changelog

Source: NEWS.md

centerline 0.3.0 (unreleased)

NEW FEATURES

  • cnt_skeleton(anchors = ...) attaches exact boundary terminals so cnt_path() can start and end at supplied boundary points with zero endpoint distance. Voronoi anchors are preserved as exact ring vertices under simplification (keep < 1).

Bug fixes

  • cnt_path() now reports when start and end points cannot be connected through the skeleton graph instead of passing an empty path to GEOS.

UPDATES

  • Skeleton routing and anchor graphs now use igraph directly; the dependency on sfnetworks has been removed. Public geometry APIs are unchanged.

centerline 0.2.5 (2026-03-12)

CRAN release: 2025-12-22

UPDATES

  • Fix CRAN Check fails on Win Old rel

centerline 0.2.4 (2025-09-09)

CRAN release: 2025-09-09

UPDATES

  • compatibility with ggplot2 4.0.0

centerline 0.2.3 (2025-03-19)

UPDATES

  • updated the geomtextpath version to 0.1.5

centerline 0.2.2 (2025-03-16)

CRAN release: 2025-03-16

UPDATES

  • the raybevel package is back on CRAN
  • Added the explicit R>= 4.1.0 dependency

centerline 0.2.1 (2024-11-05)

UPDATES

  • the raybevel package was removed from CRAN on October 22, 2024. It is not a core dependency, but it is crucial for some functions in the centerline pkg. To maintain raybevel::skeletonize accessibility for the cnt_skeleton function, raybevel is temporarily installed from GitHub.

centerline 0.2 (2024-10-01)

UPDATES

  • geom_cnt_* function family for plotting centerlines with ggplot2

centerline 0.1.3 (2024-09-29)

UPDATES

  • Switched from rlang to checkmate for type checks
  • Web-only vignettes to reduce package size

centerline 0.1.2 (2024-09-28)

UPDATES

  • Website launched with some vignettes.

centerline 0.1.1 (2024-09-27)

UPDATES

  • Added a new argument to the cnt_skeleton() function — method. It should be either "voronoi" or "straight". Depending on it, the generating skeleton method will change.

centerline 0.1 (2024-09-24)

CRAN release: 2024-09-26

UPDATES

  • CRAN first submission

centerline 0.0.5 (2024-09-23)

UPDATES

  • Major refactoring of all core functions which led to a more stable results
  • Test coverage increased

Bug fixes

centerline 0.0.4 (2024-09-13)

UPDATES

  • Two times increase in centerline guessing due to a change in the search algorithm.
  • Centerline guessing now occurs by calculating the longest path between skeleton nodes, rather than polygon nodes as it was previously. As a result, the final output is smoother at the edges.

Bug fixes

centerline 0.0.3 (2024-05-17)

UPDATES

  • Got rid of the rmapshaper dependency. Similar performance achieved only with geos in the backend.
  • Full geos support.
  • More tests covering cnt_skeleton have been added.
  • Transition from SpatVector to geos_geometry and vice versa now happens faster through the wk package, not through sf as before.

centerline 0.0.2 (2024-05-07)

UPDATES

  • cnt_path_guess performs 1.25 times faster due to a wiser usage of the igraph and geos packages. The tidygraph dependency has been removed.
  • Now, the cnt_path family returns one LINESTRING, not a collection of LINESTRINGS.

centerline 0.0.1 (2024-03-16)

NEW FEATURES

  • New function added cnt_path_guess which returns the longest centerline based on polygon only

UPDATES

  • Twofold speed increase by converting from terra objects to geos over wk package nor sf as it was earlier.
  • Added ability to densify the input polygon through geos::geos_densify

centerline 0.0.0.9000 (2024-03-01)

NEW FEATURES

  • Core functionality is added through the cnt_skeleton function
  • Super easy routing is implemented with cnt_path function, which can be applied in cases with predefined starting and ending points
