Hi, I have created a tool in C# in order to create Mask symbol around the symbol feature. To do that, I use the IMarkermask interface and the QueryMarkerMask function. Like this: IGeoFeatureLayer iGFL = iL as IGeoFeatureLayer; if (iGFL != null) { IFeatureRenderer iFR = iGFL.Renderer; if (iFR != null) { IPolygon iPG = new PolygonClass(); ISymbol iS = iFR.get_SymbolByFeature(iF); if (iS != null) { IMarkerMask iMM = iS as IMarkerMask; if (iMM != null) { IGeometry iGShape = iF.ShapeCopy; if (iGShape != null) { iGShape.Project(ESRI_Constant.Object._FocusMap.SpatialReference); pAV.ScreenDisplay.StartDrawing(pAV.ScreenDisplay.hDC, 0); iMM.QueryMarkerMask(pAV.ScreenDisplay.hDC, iDRet, iGShape, iPG); pAV.ScreenDisplay.FinishDrawing(); It works fine for a layer with a classic symbology. But if the layer use a Representation as symbology, this code doesn't work: the line ISymbol iS = iFR.get_SymbolByFeature(iF) return null. How can I get an ISymbol from a feature using an IRepresentationRenderer? Or, more generally, how can I get a mask geometry for a Marker representation? Thanks! Best regards
