Tile Extent

+
+ grid, tileExtent +
+

+ Demonstrates the use of the tileExtent property to differentiate + between the maximum extent and the tile extent for a layer. +

+
+
+

+ This example uses a layer that requests map tiles from a WMS + that only generates image responses for requests that align with + a particular tile lattice. In this case, the layer's + maxExtent does not align with that tile lattice. + To configure the layer with a tile extent that conforms to the + tile extent configured on the server, use the layer's + tileExtent property. +

+ View the tile-extent.js + source to see how this is done +
