Crop/Clip Tiled Layer data to Map extend

[roufbaba]

How can i clip/crop the tiled map data to the extend of the Map? I am creating the Merged Tiled Layer Image based upon the level row and column passed in from the SL client onto the server. Now I want to send the cropped or clipped image back to the SL client. I am doing this because this tiled map is from a cross domain origin.

Prompt help will be very much appreciated.

You could use a proxy server and set the ProxyUrl property to this server.

Hi,
Thank very much for sending the prompt reply.

I think I wasn't able to clear my point properly. I am able to send the image back to client quite succesfully. But the issue is I need to send the cropped image which should match exactly the current extend of the Map. I need to determine the offset just like in javascript using esri.TileUtils.getCandidateTileInfo

var delta = this.map._visibleDelta ? this.map._visibleDelta : this.map.__visibleDelta;
"OffsetX": candidateTileInfo.tile.offsets.x - delta.x + (this.width / 2)
"OffsetY": candidateTileInfo.tile.offsets.y - delta.y + (this.height / 2)

Thanks and Best Regards
Rouf

Hi Dominique,

Do you have any idea about the issue?

With Silverlight there is no exact equivalency to the JavaScript TileUtils class, but you can use the TileInfo property of the ArcGISTiledMapServiceLayer : http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.TiledLayer...

By using the array of Lods, the Width, the Height and the Origin, you should be able to do what you want but probably not that easy than with TileUtils class.
