3.0.8

Released: October 23, 2015

(Packaged from 2d15567)

Summary

  • Renamed SHAPE_MEMORY_MAPPED_FILE define to MAPNIK_MEMORY_MAPPED_FILE. Pass ./configure MEMORY_MAPPED_FILE=True|False to request support for memory mapped files across Mapnik plugins (currently shape, csv, and geojson).
  • Unified mapnik-index utility supporing GeoJSON and CSV formats
  • Increased unit test coverage for GeoJSON and CSV plugins
  • shape.input - refactor to support *.shx and improve handling various bogus shapefiles
  • geojson.input - make JSON parser stricter + support single Feature/Geometry as well as FeatureCollection
  • maintain 'FT_LOAD_NO_HINTING' + support >= harfbuzz 1.0.5
  • geojson.input - implement on-disk-index support

3.0.7

Released: October 12, 2015

(Packaged from e161253)

Summary

  • Removed MAPNIK_VERSION_IS_RELEASE define / mapnik-config --version not longer reports -pre for non-release versions. Use mapnik-config --git-revision instead (mapnik#3123)

3.0.0

Released: July 7th, 2015

(Packaged from e6891a0)

Summary

The 3.0 release is a major milestone for Mapnik and includes many performance and design improvements. The is the first release to provide text shaping using the harfbuzz library. This harfbuzz support unlocks improved rendering and layer for many new languages, particularly SE Asian scripts. The internal storage for working with images and geometries has been made more flexible, faster, and strongly typed. The python bindings that were previously bundled with Mapnik have now been moved to https://github.com/mapnik/python-mapnik and are versioned independently.

Notice

  • Mapnik 3.0.0 requires a compiler capable of std=c++11.
  • It is highly recommended you use the clang++ compiler on both OS X and Linux since it has robust c++11 support lower memory requirements.

  • Added premultiplied property on mapnik::image_32 / mapnik.Image to enable knowledge of premultiplied status of image buffer.

  • Added webp image encoding and decoding support (#1955)

  • Added scale-hsla image-filter that allows scaling colors in HSL color space. RGB is converted to HSL (hue-saturation-lightness) and then each value (and the original alpha value) is stretched based on the specified scaling values. An example syntax is scale-hsla(0,1,0,1,0,1,0,1) which means no change because the full range will be kept (0 for lowest, 1 for highest). Other examples are: 1) scale-hsla(0,0,0,1,0,1,0,1) which would force all colors to be red in hue in the same way scale-hsla(1,1,0,1,0,1,0,1) would, 2) scale-hsla(0,1,1,1,0,1,0,1) which would cause all colors to become fully saturated, 3) scale-hsla(0,1,1,1,0,1,.5,1) which would force no colors to be any more transparent than half, and 4) scale-hsla(0,1,1,1,0,1,0,.5) which would force all colors to be at least half transparent. (#1954)

  • The shapeindex tool now works correctly with point 3d geometry types

2.2.0

Released June 3rd, 2013

(Packaged from 9231205)

Summary: The 2.2.0 release is primarily a performance and stability release. The code line represents development in the master branch since the release of 2.1.0 in Aug 2012 and therefore includes nearly a year of bug-fixes and optimizations. Nearly 500 new tests have been added bring the total coverage to 925. Shapefile and PostGIS datasources have benefited from numerous stability fixes, 64 bit integer support has been added to support OSM data in the grid renderer and in attribute filtering, and many fixes have landed for higher quality output when using a custom scale_factor during rendering. Critical code paths have been optimized include raster rendering, xml map loading, string to number conversion, vector reprojection when using epsg:4326 and epsg:3857, hextree encoding, halo rendering, and rendering when using a custom gamma. Mapnik 2.2 also compiles faster than previous releases in the 2.x series and drops several unneeded and hard to install dependencies making builds on OS X and Windows easier than any previous release.

  • Removed 3 depedencies without loosing any functionality: ltdl, cairomm and libsigc++ (#1804,#806,#1681)

  • Added 64 bit integer support in expressions, feature ids, and the grid_renderer (#1661,#1662,#1662)

  • Added the ability to disable the need for various dependencies: proj4, libpng, libtiff, libjpeg

  • Added faster reprojection support between epsg:3857 and epsg:4326 (#1705,#1703,#1579)

  • Added colorize-alpha image filter that applies user provided color gradients based on level of alpha. Accepts one or more colors separated by commas. Each color can be paired with an offset value separated by a space that is either 0-100% or 0.0-1.0. An offset of 0 is implied and the default. For background on where this design came from see http://www.w3.org/TR/SVG/pservers.html#GradientStops. A simple example of colorizing alpha into a "rainbow" is colorize-alpha(blue,cyan,lightgreen, yellow, orange, red). An example of using offsets and the variety of supported color encodings is to produce a ramp which sharp contrast between blue and cyan is colorize-alpha(blue 30%, cyan, yellow 0.7 , rgb(0%,80%,0%) 90%) (#1371).

  • Fixed concurrency problem when using cursors in postgis plugin (#1823,#1588)

  • Added C++ api for overriding scale_denominator to enable rendering at fixed scale (#1582)

  • Added Layer buffer-size that can be used to override Map buffer-size to avoid over-fetching of data that does not need to be buffered as much as other layers. Map level buffer-size will be default if layers do not set the option. Renamed a previously undocumented parameter by the same name that impacted clipping extent and was not needed (clipping padding should likely be a symbolizer level option) (#1566)

  • Support for encoding literal postgres types as strings 69fb17cd3/#1466

  • Fixed zoom_all behavior when Map maximum-extent is provided. Previously maximum-extent was used outright but now the combined layer extents will be again respected: they will be clipped to the maximum-extent if possible and only when back-projecting fails for all layers will the maximum-extent be used as a fallback (#1473)

  • Compile time flag called PLUGIN_LINKING to allow input datasource plugins to be statically linked with the mapnik library (#249)

  • PostGIS: Added a new option called autodetect_key_field (by default false) that if true will trigger autodetection of the table primary key allowing for feature.id() to represent globally unique ids. This option has no effect if the user has not manually supplied the key_field option. (#804)

  • Cairo: Add full rendering support for markers to match AGG renderer functionality (#1071)

  • Fix Markers rendering so that ellipse height/width units are pixels (previously were unintentionally radii) (#1134)

The reverted change is seen below as "Fix Markers rendering so that ellipse height/width units are pixels (previously were unintentionally radii)". Issue tracking this is #1163

  • XML: Fixed to avoid throwing if a <Parameters> element is encountered (which is supported in >= 2.1.x)

  • Support for PostGIS 2.0 in the pgsql2sqlite command (e69c44e/47e5b3c)

Mapnik 2.0.0

Released September 26, 2011

(Packaged from 5b4c20eab3)

  • Add minimum-path-length property to text_symbolizer to allow labels to be placed only on lines of a certain length (#865)

  • Add support for png quantization using fixed palettes (#843)

  • Add AlsoFilter functionality - https://github.com/mapnik/mapnik/wiki/AlsoFilter

  • SQLite Plugin: optimize i/o using shared cache and no mutexes (#797)

  • Directly link input plugins to libmapnik to avoid having to set dlopen flags from binding languages (#790)

  • Throw an error during registration for fonts which Freetype2 does not report a family or style name (r2985).

  • Fixed quoting syntax for "table"."attribute" in PostGIS plugin (previously if table aliases were used quoting like "table.attribute" would cause query failure) (r2979).

  • Added the ability to control the PostGIS feature id by suppling a key_field to reference and integer attribute name (r2979).

  • Added alternative, more robust proj_transform functions to project a bbox using more points than just the four corners to ensure an optimally sized bbox despite proj4 out of bounds conditions. (olt)

  • Added map.base parameter that can be set to control where files with relative paths should be interpreted from when a map is loaded from a string or saved to a string. It defaults to an empty string which means that the base path will be the current working directory of the mapnik process. When a stylesheet is read from a file that files directory is used. And a custom value can still be passed as an argument to load_map_from_string().

  • Added python function render_grid to allow conversion of grid buffer to python object containing list of grid pixels, list of keys, and a and dictionary of feature attributes.

  • Added new rendering backend, grid_renderer, that collects the attributes of rendered features and burns their ids into a grid buffer.

  • Added optional maximum-extent parameter to map object. If set will be used, instead of combined layer extents, for return value of map.zoom_all(). Useful in cases where the combined layer extents cannot possibly be projected into the map srs or the user wishes to control map bounds without modifying the extents of each layer.

Mapnik 0.7.1

Released March 23, 2010

(Packaged from r1745/db89f1ca75)

  • Rasters: Various fixes and improvements to 8bit png output (#522,#475)

  • XML: Save map buffer_size when serializing map.

  • SCons: Added new build options PRIORITIZE_LINKING and LINK_PRIORITY. The first is a boolean (default True) of whether to use the new sorting implementation that gives explcit preference to custom or local paths during compile and linking that will affect builds when duplicate libraries and include directories are on the system. LINK_PRIORITY defaults to prioritizing internal sources of the mapnik source folder, then local/user installed libraries over system libraries, but the option can be customized. Sorting not only ensures that compiling and linking will more likely match the desired libraries but also gives more likelyhood to avoid the scenario where libraries are linked that don`t match the includes libmapnik compiled against.

  • XML: Fixed behavior of PolygonPatternSymbolizer and LinePatternSymbolizer whereby width, height, and type of images is actually allowed to be optionally ommitted (#508). This was added in r1543 but only worked correctly for PointSymbolizer and ShieldSymbolizer.

  • Fixed reading of PostGIS data on Big Endian systems (#515)

  • PostGIS: Added better support for alterative schemas (#500)

  • AGG Renderer - Enforced default gamma function on all symbolizers to ensure proper antialiasing even when gamma is modified on the PolygonSymbolizer. (#512)

  • PNG: fixed png256 for large images and some improvements to reduce color corruptions (#522)

  • PNG: Added new quantization method for indexed png format using hextree with full support for alpha channel. Also new method has some optimizations for color gradients common when using elevation based rasters. By default old method using octree is used. (r1680, r1683, #477)

  • PNG: Added initial support for passing options to png writter like number of colors, transparency support, quantization method and possibly other in future using type parameter. For example "png8:c=128:t=1:m=h" limits palette to 128 colors, uses only binary transparency (0 - none, 1 - binary, 2 - full), and new method of quantization using hextree (h - hextree, o - octree). Existing type "png256" can be also written using "png8:c=256:m=o:t=2" (r1680, r1683, #477)

Mapnik 0.7.0

Released January, 19 2010

(Packaged from r1574/a0da946be9)

  • Core: Fixed linking to external libagg (r1297,r1299)

  • Core: Completed full support for PPC (Big endian) architectures (r1352 -> r1357)

  • Gdal Plugin: Added support for Gdal overviews, enabling fast loading of > 1GB rasters (#54)

    • Use the gdaladdo utility to add overviews to existing GDAL datasets

  • PostGIS: Added an optional geometry_table parameter. The geometry_table used by Mapnik to look up metadata in the geometry_columns and calculate extents (when the geometry_field and srid parameters are not supplied). If geometry_table is not specified Mapnik will attempt to determine the name of the table to query based on parsing the table parameter, which may fail for complex queries with more than one from keyword. Using this parameter should allow for existing metadata and table indexes to be used while opening the door to much more complicated subqueries being passed to the table parameter without failing (#260, #426).

  • PostGIS Plugin: Added optional geometry_field and srid parameters. If specified these will allow Mapnik to skip several queries to try to determine these values dynamically, and can be helpful to avoid possible query failures during metadata lookup with complex subqueries as discussed in #260 and #436, but also solvable by specifying the geometry_table parameter. (r1300,#376)

  • PostGIS: Added an optional extent_from_subquery parameter that when true (while the extent parameter is not provided and estimate_extent is false) will direct Mapnik to calculate the extent upon the exact table or sql provided in the table parameter. If a sub-select is used for the table parameter then this will, in cases where the subquery limits results, provide a faster and more accurate layer extent. It will have no effect if the table parameter is simply an existing table. This parameter is false by default. (#456)

  • PostGIS Plugin: Added !bbox! token substitution ability in sql query string. This opens the door for various complex queries that may aggregate geometries to be kept fast by allowing proper placement of the bbox query to be used by indexes. (#415)

    • Pass the bbox token inside a subquery like: !bbox!

    • Valid Usages include:

      (Select ST_Union(geom) as geom from table where ST_Intersects(geometry,!bbox!)) as map (Select * from table where geom && !bbox!) as map

  • PostGIS Plugin: Added scale_denominator substitution ability in sql query string (#415/#465)

    • Pass the scale_denominator token inside a subquery like: !scale_denominator!

    • e.g. (Select * from table where field_value > !scale_denominator!) as map

  • PostGIS Plugin: Added support for quoted table names (r1454) (#393)

  • PostGIS: Add a persist_connection option (default true), that when false will release the idle psql connection after datasource goes out of scope (r1337) (#433,#434)

  • PostGIS: Added support for BigInt (int8) postgres type (384)

  • PostGIS Plugin: Throw and report errors if SQL execution fails (r1291) (#363, #242)

  • PNG: Added support for semi-transparency in png256 output (#477,#202)

  • PolygonSymbolizer: Added gamma attribute to allow for dilation of polygon edges - a solution to gap artifacts or "ghost lines" between adjacent polygons and allows for slight sharpening of the edges of non overlapping polygons. Accepts any values but 0-1 is the recommended range.

  • TextSymbolizer: Large set of new attributes: text_transform, line_spacing, character_spacing, wrap_character, wrap_before, horizontal_alignment, justify_alignment, and opacity.

    • More details at changesets: r1254 and r1341

  • SheildSymbolizer: Added special new attributes: unlock_image, VERTEX placement, no_text and many attributes previously only supported in the TextSymbolizer: allow_overlap, vertical_alignment, horizontal_alignment, justify_alignment, wrap_width, wrap_character, wrap_before, text_transform, line_spacing, character_spacing, and opacity.

    • More details at changeset r1341

  • XML: Added support for using CDATA with libxml2 parser (r1364)

  • XML: Fixed memory leak in libxml2 implementation (#473)

  • XML: Added function to serialize map to string, called mapnik.save_map_to_string() (#396)
