CurrentWaterMarkIndex returns the index of the most recent watermark created by the CreateWaterMark method. The return value is an watermark identifier in document's watermarks collection and can be used in CurrentWaterMarkIndex, PDFPAGE_DrawWatermark, PDFPAGE_Watermark.
When you use watermark functions, you must set the watermark to the page before all other output functions.
