Changelog

3.7.1

  • Mapnik 3.7.0 was not properly published to npm with node-pre-gyp. Releasing again with fix.
  • Fix to SSE_MATH flag during building

3.7.0

Updated to 3.0.18 of mapnik. See here.

3.6.2

Updated to 3.0.15 of mapnik. The full changelog for this release is located here.

3.6.1

Updated for a fix associated with mapnik-vector-tile where images could be requested that would have a width or height of zero resulting in exceptions.

Several fixes associated with different mapnik by updating to use 3.0.14. Please see mapnik change log for specifics. In general note worthy changes from mapnik include stricter geojson parsing, fixes for raster plugin, fixes to image scaling, changing the meaning of filter-factor, and improvements to the the TIFF decoder.

Due to changes in the mapnik core version during this update you should see some changes in the image rescaling of raster and gdal plugin source data. This will definitely change the expected output. This is due to fixes in long standing bugs in the mapnik library.

  • Updated to [email protected]
  • Mapnik minimum version updated to 3.0.14. Does not work with mapnik 3.1.x currently.
  • Fixed tests around zlib compression and decompression when comparing to node's implementation
  • Fixes rare situation of seg faults during mapnik-vector-tile image processing.
  • Corrects the resolution of images in mapnik-vector-tile when using parameters from postgis plugin.
  • Updated to use font_engine instance() method explicitely, reflecting on changes brought by 3688

3.6.0

This release has major performance and stability improvements.

The biggest change is the move to https://github.com/mapbox/wagyu for clipping polygons, which is faster and results in more robust results than the previous implementation based off the "clipper" http://www.angusj.com/delphi/clipper.php. The "clipper" was known to hang on very large polygons and could output self-intersecting polygons.

The second largest change is the update of all major C/C++ dependencies. The changelogs for each are listed below. The highlights are 1) the performance improvements in webp 1.6.0, 2) the many crashes fixed in harfbuzz (harfbuzz/harfbuzz#139), and critical security bugs fixed in libpng, libjpeg, and libtiff.

The third most important set of changes were to node-mapnik directly: for performance many functions now can premultiply as part of another async operation (to avoid needing an additional threadpool access for async premultiply - this matters under load when the threadpool may be full since access can block). And many functions that allocate images now protect from extreme allocation that could hang a machine and result in OOM. Additionally the address sanitizer caught several cases of undefined behavior.

3.5.14

  • Added the mapnik.VectorTile.info command that returns an object that inspects buffers and provides information about vector tiles.
  • Updated mapnik-vector-tile to 1.0.2

3.5.0

This is a major update and reflects a large number of changes added into node-mapnik due to update of the Mapbox Vector Tile Specification. As part of this the mapnik-vector-tile library was updated to 1.0.0. Therefore, a large number of interfaces changes have taken place around the mapnik.VectorTile object.

It is important to know that the concept of width and height have been removed from mapnik.VectorTile objects. This is replaced by the concept of tileSize. While width and height were based on the concept of an Image size created from a vector tile, tileSize is directly related to the extent as defined in the Layer of a vector tile. For understanding what the Layer and extent is please see the Vector Tile Specification. This also changed the buffer_size arguments that were commonly used in many Vector Tile methods, which was also based on the Image size. The vector tile object now contains a bufferSize which represents the buffer added to the layer extent in a tile.

Internally, all methods now depend on V2 tiles, however, any V1 tiles that are loaded into a mapnik.VectorTile object will automatically be updated.

Summary of changes:

  • mapnik.VectorTile.addData now verifies buffers validity and internally updates v1 tiles to v2
  • mapnik.VectorTile.addDataSync now verifies buffers validity and internally updates v1 tiles to v2
  • mapnik.VectorTile.setData now verifies buffers validity and internally updates v1 tiles to v2
  • mapnik.VectorTile.setDataSync now verifies buffers validity and internally updates v1 tiles to v2
  • mapnik.VectorTile.addImage now takes a mapnik.Image object rather then a buffer, it also takes optional arguments image_scaling and image_format.
  • mapnik.VectorTile.addImageBuffer replaces the old functionality of of mapnik.VectorTile.addImage
  • Added mapnik.VectorTile.addImageSync and made mapnik.VectorTile.addImage accept a callback.
  • Added mapnik.VectorTile.addImageBufferSync and made mapnik.VectorTile.addImageBuffer accept a callback.
  • mapnik.VectorTile.height() method is removed
  • mapnik.VectorTile.width() method is removed
  • mapnik.VectorTile.parse() method is removed
  • mapnik.VectorTile.IsSolid() method is removed
  • mapnik.shutdown() is removed
  • Removed the dependency on libprotobuf library
  • Lowered memory requirements for vector tile creation and vector tile operations.
  • Duplicate layer names in mapnik.VectorTile objects are no longer permitted.
  • Added new mapnik.VectorTile.extent() method which returns the bounding box of a tile in EPSG:3857
  • Added new mapnik.VectorTile.bufferedExtent() method which returns the bounding box including buffer of a tile in EPSG:3857
  • Added new mapnik.VectorTile.emptyLayers() method which returns the name of layers which were not added to a tile during any tile rendering operation.
  • Added new mapnik.VectorTile.paintedLayers() method which returns the name of layers which were considered painted during rendering or layers that contain data.
  • Added new mapnik.VetorTile.tileSize property.
  • Added new mapnik.VetorTile.bufferSize property.
  • Updated many of the default configuration options on mapnik.VectorTile class methods
  • Removed the concept of path_multiplier from the code entirely.
  • Added optional arguments of tile_size and buffer_size to mapnik.VectorTile constructor.

3.4.19

  • Upgraded to protozero v1.3.0
  • Fixed invalid usage of mapbox::variant that was causing windows compiler crash

Notable Changes in Mapnik v3.0.10 include:

  • A shapefile index now is skipped instead of causing an error to be throw. The shapefile plugin will then proceed by reading without using an index. It is advisable to regenerate the indexes to maintain top performance.

Notable changes in the Mapnik SDK include:

  • sqlite 3100000->3110000
  • libpng 1.6.20->1.6.21
  • postgres 9.4.5->9.5.1

  • Binaries updated to use Mapnik v3.0.9-57-g9494bc1 and mapnik-packaging@039aa0d

Notable Changes in Mapnik v3.0.9-57-g9494bc1 include:

3.4.13

  • Upgraded to [email protected]
  • Upgraded to [email protected]
    • Fixed premultiplication bug in raster encoding (#170)
  • Binaries updated to use Mapnik v3.0.9-48-gbb8cd10 and mapnik-packaging@039aa0d

Notable Changes in Mapnik v3.0.9-48-gbb8cd10 include:

  • BREAKING: any .index files accompanying a .shp must now be regenerated otherwise an error will be throw like Error: invalid index file. To avoid this error you can either delete the existing .index files, or ideally run shapeindex (or mapnik-shapeindex.js) to recreate the .index. The trigger for this change was an optimization that required a new binary format for the shapefile indexes (mapnik/mapnik#3217). It was a mistake of @springmeyer to bring this into node-mapnik minor release (I'm sorry).
  • WARNING: index files generated with this newer Mapnik are invalid for older versions of Mapnik.
  • Compare: https://github.com/mapnik/mapnik/compare/v3.0.9...v3.0.9-48-gbb8cd10
  • The shapeindex command now has a --index-parts option

    • Default format is now webp encoding rather than jpeg (to support transparency)
    • Default scaling is now bilinear rather than near
  • Binaries updated to use Mapnik v3.0.9-17-g75cb954 and mapnik-packaging@e29a81e

Notable Changes in Mapnik 3.0.9-17-g75cb954 include:

Notable changes in the Mapnik SDK include:

  • Upgrade harfbuzz 1.0.6 -> 1.1.2
  • Upgrade pixman 0.32.6 -> 0.32.8
  • Upgrade cairo 1.14.2 -> 1.14.4

  • Upgrade icu_version2 55_1 -> 56_1

3.4.10

  • Now bundling the mapnik-index command (mapnik#545)
  • Added process_all_rings option to VectorTile.composite, VectorTile.addGeoJSON, and Map.render. This option enables invalid ring to be processed (and potentially kept during re-encoding) when creating vector tiles. By default this is set to false. Use with caution.
  • Added enum for all polygon fill types under mapnik.polygonFillType. Options are nonZero, evenOdd, positive, and negative
  • Added fill_type option to VectorTile.composite, VectorTile.addGeoJSON, and Map.render. By default this is set to mapnik.polygonFillType.nonZero
  • Added multi_polygon_union option to VectorTile.composite, VectorTile.addGeoJSON, and Map.render. By default this is set to true. This will cause multipolygons to undergo a union operation during vector tile creation.
  • Added simplify_distance option to VectorTile.composite.
  • Added max_extent (bbox) option to VectorTile.composite. By default it is unset which means no clipping extent will be used for the operation. If provided the data will be restricted to this extent.
    • Landed in https://github.com/mapnik/node-mapnik/commit/ef3b12a36f529a1a8fbb70f4ddd6a92e1bd22008
    • Previously compositing was using a hardcoded global extent of -20037508.34,-20037508.34,20037508.34,20037508.34 which meant that all vector tile data was being clipped to global extents. This was harmless in all cases except when data contained data outside of global extents intentionally in order to avoid rendering of lines and blurs being visible at tile boundaries.
  • Added reencode (boolean) option to VectorTile.composite. If true will trigger re-rendering even if the z/x/y of all tiles matches. If false (the default) then tiles will be concatenated for best performance.
  • Updated mapnik-vector-tile to v0.14.1
  • Binaries updated to use Mapnik v3.0.9-rc2 and mapnik-packaging@6f2f178

  • Updated to use mapnik-vector-tile 0.12.0

Notable Changes in Mapnik 3.0.5 include:

  • PostGIS plugin: added key_field_as_attribute option. Defaults to True to preserve current behavior of having the key_field added both as an attribute and as the feature.id value. If key_field_as_attribute=false is passed then the attribute is discarded (mapnik/mapnik#3115)
  • CSV plugin has been further optimized and has gained experimental support for on-disk indexes (mapnik/mapnik#3089)
  • SVG parser now fallsback to using viewbox if explicit dimensions are lacking (mapnik/mapnik#3081)
  • Fixed parsing colors in hexadecimal notation (mapnik/mapnik#3075)

3.4.7

  • Rebuilt with Mapnik 3.0.5
  • Added ability to create an image using a Buffer object. It should be noted that this should be used very carefully as the lifetime of the Image object is tied to that of the Buffer. If the buffer object is garbage collect this could result in a segfault.
