Example 2 with RenderRequest

use of org.opentripplanner.analyst.request.RenderRequest in project OpenTripPlanner by opentripplanner.

the class SurfaceResource method differenceTileGet.

/**
 * Renders a raster tile for showing the difference between two TimeSurfaces.
 * This service is included as a way to provide difference tiles using existing mechanisms in OTP.
 * TODO However, there is some room for debate around how differences are expressed in URLs.
 * We may want a more general purpose mechanism for combining time surfaces.
 * For example you could make a web service request to create a time surface A-B or A+B, and the server would give
 * you an ID for that surface, and then you could use that ID anywhere a surface ID is required. Perhaps internally
 * there would be some sort of DifferenceTimeSurface subclass that could just drop in anywhere TimeSurface is used.
 * This approach would be more stateful but more flexible.

 * @param surfaceId The id of the first surface
 * @param compareToSurfaceId The id of of the surface, which is compared to the first surface
