Hi there,
Today I had to extract the binary references of a specific layer and to my surpirse it worked like a charm with the following code snippet:
var binaryReferences = new List<CIMBinaryReference>();
// fetch binary references which are needed in order to properly display graphic layers
var graphicsLayers = map.GetLayersAsFlattenedList().OfType<GraphicsLayer>();
foreach (var graphicLayer in graphicsLayers)
{
var layerDoc = new LayerDocument(graphicLayer);
var cimLayerDoc = layerDoc.GetCIMLayerDocument();
var elementStorageList = cimLayerDoc.BinaryReferences.Where(br => br.Object is CIMElementStorage);
binaryReferences.AddRange(elementStorageList);
}
At another point I have to do this for a whole map, but unfortunately the only way to get the binary references of a map is to save it to a .mapx file, read and parse it as a json, which has a horrible performance if the map gets huge. Is there a way to get the CIMLayerDocument somehow in memory like I did it with the layer? There is also no class named 'MapDocument' in the public API.
map.SaveAsFile("C:\data\map.mapx");
var json = File.ReadAllText("C:\data\map.mapx");
var doc = CIMLayoutDocument.FromJson(json);
