string desktop_path = Environment.GetFolderPath(
Environment.SpecialFolder.Desktop);

Autodesk.Revit.DB.View view = UIApp.ActiveUIDocument.Document.ActiveView;

string filepath = Path.Combine(desktop_path,
view.Name);

ImageExportOptions img = new ImageExportOptions();
img.ZoomType = ZoomFitType.Zoom;
img.PixelSize = 96;
img.ImageResolution = ImageResolution.DPI_600;
img.FitDirection = FitDirectionType.Horizontal;
img.ExportRange = ExportRange.CurrentView;
img.HLRandWFViewsFileType = ImageFileType.PNG;

Create a new view displaying only the element you wish to see:

Or:

A. isolate element in view + Zoom to Fit

B. calculate position of element (boundingbox) + Zoom to those coordinates

And then export with:  ExportRange = VisibleRegionOfCurrentView
