pbf2png
PBF(MVT) tiles to PNG convertor - QtPBFImagePlugin example/benchmark app. Converts a directory of Mapbox vector tiles to PNG tiles.
Build
qmake pbf2png.pro
make
Usage
pbf2png [options] DIR
Use pbf2png -h for help. The parameters should be self-explanatory, except the
-M - tile name mask parameter. It's only there because of the notoriously known
design flaw in the Mapbox vector tiles specification - the missing zoom level
in the tile data. To render a tile, a workaround that fetches the zoom level from
the file name (or somewhere else) is required. The default mask(regular expression)
is ([0-9]+).* which should fit all common tile name schemes like $z-$x-$y.pbf,
$z_$y_$x.mvt, etc.
Styles
See the QtPBFImagePlugin documentation for how to set the style used for rendering the tiles. For the default OpenMapTiles data schema and the default OSM-Liberty style nothing needs to be done.
