One of the tools is an export map function, I simply want to export a JPG image of the map control. The map contains a single layer, the tiled Topographic Map service hosted on ArcGIS Online.</SPAN><BR /><BR /><SPAN>When accessing the WriteableBitmap I am getting a security exception (???WriteableBitmap has protected content. Pixel access is not allowed???). This is expected as ArcGIS Online is on a different domain. To get around this, I created a proxy and assigned the proxy URL to the Topographic Map layer inside the Builder application. Still getting the error message.</SPAN><BR /><BR /><SPAN>If I create a simple Silverlight application with a map control and the Topographic map layer, the security exception is no longer raised if I specify the ProxyURL property for the layer.</SPAN><BR /><BR /><SPAN>Is the proxy expected to work in this situation? I know I can create a preview map control in my addin window, copy the map layers and graphics from main map and then export the preview map, but I would like to avoid doing this.</SPAN><BR /><BR /><SPAN>Thanks</SPAN><BR /><SPAN>Alex</SPAN></BODY></HTML> Mon, 13 May 2013 13:54:51 GMT https://community.esri.com/t5/arcgis-viewer-for-silverlight-questions/silverlight-viewer-1-0-1-exporting-map-image-to/m-p/385525#M1113 AlexZlotin 2013-05-13T13:54:51Z Re: Silverlight Viewer 1.0.1: exporting map image to WriteableBitmap fails with proxy https://community.esri.com/t5/arcgis-viewer-for-silverlight-questions/silverlight-viewer-1-0-1-exporting-map-image-to/m-p/385526#M1114 <HTML><HEAD></HEAD><BODY><SPAN>Hi, did you ever get an answer to this question?</SPAN><BR /><BR /><SPAN>Thanks in advance,</SPAN><BR /><BR /><SPAN>Sergio</SPAN></BODY></HTML> Fri, 09 Aug 2013 21:36:14 GMT https://community.esri.com/t5/arcgis-viewer-for-silverlight-questions/silverlight-viewer-1-0-1-exporting-map-image-to/m-p/385526#M1114 SergioGalindo 2013-08-09T21:36:14Z
