Erica Fischer 403828d2f7 Change all these places where I said "extent" but really meant "area" 2022-10-04 16:12:33 -07:00
Erica Fischer af1a7ed7ae Once features can't possibly fit in a tile, stop trying (#9) 
* Stop adding features to a tile if it can't possibly work

* Add --integer and --fraction options to tippecanoe-decode

* Carry the strategies field from tileset metadata through tile-join

* Update changelog

* Assign different codes to different kinds of error exits

Erica Fischer 67cd9d8d85 Reduce tippecanoe memory usage (#5) 
* Change JSON objects to a union type to use less memory

* Stop storing the string representation of JSON numbers

* Restore the ability to create features with large integer attributes

* Make sure large-integer feature IDs still behave as before

* Add missing #include

* Don't preallocate as much space for arrays and objects

* Treat inability to check free disk space as a warning, not an error

* Update changelog and version

Eric Fischer 0acdeef525 Fix null pointer crash when looking for feature extent in filter output 2018-10-22 13:26:53 -07:00
Eric Fischer c9eed0d457 Be careful to remove null attributes from prefilter/postfilter output 2018-06-06 11:48:57 -07:00
Eric Fischer 1b26becad9 Clear up some confusion about attribute count and external references 
Now the count is always adjacent to whereever the key/value pair is
stored, and is not kept in the serial feature object other than as
the length of the vectors of keys and values.

Eric Fischer a8a342f701 Send dot-dropping through the same pipeline. 
The first feature in a tile can never be dropped, since there is
no previous feature to attach its properties to.

Remove the previous special case that reset the dropping counter
at the first feature within each tile proper (as opposed to the
first feature in each tile, including its buffer, which is now
the one that is guaranteed to be preserved).

Eric Fischer 200f6777ba Fix layer list in tilestats when filtering and tile-joining. 
(The feature count when filtering will be the sum of features
across tiles instead of filters from the original input, since
the filter reader doesn't know what the original input feature
set was.)
