✨ Features and improvements

0.4.1

✨ Features and improvements

  • Update MBUtil description in README.md (#4) (by acalcutt)
  • Add message if file does not exist.

0.4.0

Added

  • PMTiles ↔ Disk: Export tiles from a .pmtiles file to a folder structure, or import a tile folder into a new .pmtiles file (disk_to_pmtiles, pmtiles_to_disk).
  • MBTiles ↔ PMTiles direct conversion: Convert between .mbtiles and .pmtiles without an intermediate disk step (mbtiles_to_pmtiles_cmd, pmtiles_to_mbtiles_cmd). Detected automatically by file extension.
  • PMTiles metadata dump: mb-util archive.pmtiles dumps prints metadata to the terminal.
  • Tile deduplication on PMTiles→MBTiles: --do_compression and --hash_type flags work when converting PMTiles to MBTiles.
  • Metadata helpers: normalize_metadata(), prepare_metadata_for_mbtiles(), get_tile_ext(), pmtiles_header_to_metadata().
  • PMTiles reference Python library included as a git submodule.
  • Full unit test suite (test/test_pmtiles.py) and GitHub Actions CI workflow.
  • Docker image with multi-arch support (amd64, arm64).

Fixed

  • Y-coordinate flipping between TMS (MBTiles) and XYZ (PMTiles) coordinates.
  • Out-of-bounds tile IDs are skipped with a warning instead of crashing.
  • scheme metadata key removed when writing PMTiles output; scheme: tms added when writing MBTiles output.
  • Center zoom fallback to (min_zoom + max_zoom) // 2 when value is missing or zero.
  • Graceful NotImplementedError when PMTiles submodule is not initialized.
  • Vector tiles (PBF) are gzip-compressed when writing to PMTiles if not already compressed.
  • json metadata row (vector_layers, tilestats) correctly round-trips between MBTiles and PMTiles formats.
  • optimize_database connection not closed after PMTiles→MBTiles conversion (caused "database is locked" errors).

0.3.0

  • Initial public release with MBTiles import/export support.
