Why (new Image(el.GetXObject())).Export("X") < (element.Export()).Save("X",ImageFormat.Jpeg)?

element.GetBitmap()).Save(“Path”,ImageFormat.Jpeg) is using GDI+ (or .NET) to save a Syste.Drawing.Bitmap (or similar) to JPEG whereas Export() is using optimized functions in PDFNet (which do not use GDI+).

I guess you should choose to use only one method instead of both?
