Insert current watermark into a PDF page.
If current watermark is treated as page content (which is specified by flags of WatermarkSettings when current watermark is constructed), Foxit PDF SDK will generate content for the input PDF page by default after the watermark is inserted successfully. In this case , if user wants to render the PDF page correctly after this function has been called successfully, user is recommended to call function PDFPage.StartParse with parameter is_reparse true before rendering; otherwise, the page content may not be rendered as expected.
[in] | page | A PDF page, to which current watermark would be inserted. This page should belong to the same document as current watermark belongs to. And the page should have been already parsed. |

Check whether current object is empty or not.
