Erica Fischer 2ec6180003 Fix "strategies" accounting for 0-length linestrings and degenerate polygons (#137)
* Dropping a 0-length feature doesn't count as dropping-as-needed

* Add an option not to reduce tiny polygons to dust at maxzoom

* Add test for prevention of tiny polygon reduction at maxzoom

* Fix accounting for tiny polygons not to include degenerate geometries

* Revert "Add test for prevention of tiny polygon reduction at maxzoom"

This reverts commit f931bbd73e.

* Revert "Add an option not to reduce tiny polygons to dust at maxzoom"

This reverts commit 03f0882bb6.

* Fix tests

* Another test that no longer has any really tiny polygons

* Oops, that broke LineString simplification

* This time for sure!

* Update changelog and version

Erica Fischer afc7ca01a2 Calculate an antimeridian-adjusted bounding box in tileset metadata (#82)
* Calculate a new antimeridian-adjusted bounding box

* Add antimeridian bounding box to pmtiles, dirtiles, and tile-join

* Don't take out-of-bounds latitudes into account in the adjusted bbox

* Update changelog

* Forgot to adjust tests after the last change

Erica Fischer c58a8e3b97 Round coordinates instead of truncating them (#60)
* Round coordinates instead of truncating them

* Update all the tests for coordinate rounding changes

* Curses, integer division still truncates

* Fix tests

* Also round instead of shifting when looking for no-op linetos

* Should I worry that the same change for moveto doesn't change any tests?

* Also round instead of shifting when scaling down to maxzoom resolution

* Replace another explicit shift, for origin point

* Round instead of shift when writing clipped geometries to the next zoom

* Fix low-zoom gridding and smaller-than-a-pixel checks

* Don't guess an excessively large maxzoom when there is only one feature

* Add a test for guessing the maxzoom of a single point

* Explicitly sort by index if no other order distinguishes features

* Another affected test

Erica FischerandBrandon Liu 3b2599f587 Add support for pmtiles output format (#55)
* add pmtiles.hpp from github.com/protomaps/PMTiles [#10]

* tippecanoe main writes pmtiles output. [#10]

* detect output format using suffix
* after mbtiles is done writing, replace with pmtiles based on map/image tables.
* add method to write_json for writing json sub-object.

* tippecanoe-decode reads pmtiles input. [#10]

* tile-join reads and writes pmtiles. [#10]

* pmtiles test suite for decode and tile-join [#10]

* add base GitHub CI action for compiling and test suite.

* update pmtiles.hpp with z>15 fix

* Fix some ordering problems with pmtiles decode

* Pmtiles should also pass the raw tiles tests

* Eradicate spaces from tileset metadata JSON fields

* Eradicate spaces from more test fixtures

* Update more tests

* Pmtiles tests pass now too

* Remove unnecessary sort (and make indent)

* Update changelog

* The allow-existing test for pmtiles needs -o, not -e

* Declare --allow-existing to be unsupported for pmtiles.

It was always a bad idea even for mbtiles.

Erica Fischer a447dfc089 Extra coordinate precision; feature ordering; compression improvements
* Add an option to retain extra coordinate precision at maxzoom

* Make sure not to shift away the extra detail from coordinates

* Add an option to convert double-precision attributes to single

* Sort attribute values in tiles to make them compress a little better

* Slightly improve polygon simplification

By choosing a point that would be retained after simplification
to be the start/end point that always gets retained

* I regret making all of these tests involve polygons

* Add an option to specify the size of tiny polygons

* Fix accidental requiring of argument for --single-precision

* Guard against duplicate points when generating "sizes" for them

* Restore the intended behavior that tiny polygons don't get simplified

* Make the extra detail settable rather than always maximizing it

* Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)"

This reverts commit fec5e8354c.

* Add an option to prevent choosing a base zoom higher than the maxzoom

* Keep the drop rate high enough when the basezoom gets constrained

* Revert "Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)""

This reverts commit db6bc27d9e.

* Add --order-by and --order-descending options

* Accept multiple --order-by and --order-descending-by sort keys
