title: Custom Canvas Tiles
shortdesc: Renders tiles with TMS coordinates for debugging.
docs: >
The black grid tiles are generated on the client with an HTML5 canvas.
The displayed TMS tile coordinates are produced using a custom template
for TMS, the vector tile source's 512 pixel tile grid and the
zDirection
setting for vector tiles.
Notice how the country polygons can be split between tiles and vector
labels may appear in each tile.
