pmtiles-serve serves tiles with TMS scheme #8

Closed typebrook closed 3 years ago

typebrook commented 3 years ago

Problem: Now pmtiles-serve directly uses y value in sqlite table tiles from MBTiles, which is TMS scheme.

In fact, MBTiles always follow TMS scheme. So if we want to serve tiles with XYZ scheme, the y value should be


# y is the value in MBTiles
2^z - 1 - y

@typebrook can you try with version 0.0.5?
