   Hi, guys!
I need to add  a signature to the end of text. But  I don't know the length of the text  in advance. Is it possible to determine the end programmatically?

	Hi Liveny! Why not try this one: http://www.quickpdflibrary.com/faq/how-do-i-apply-a-digital-signature-to-a-pdf-using-quick-pdf-library.php You can add a signature to a file and it doesn't matter where your textcontent is. The length of your text you can determine while using the textextraction counting the characters. Cheers and welcome here, Ingo

	Hi! thx for your answer. May be I didn't make myself clear. The point is I don't need a DIGITAL signature. I want to add facsimile. =)

	;-) Thx, but in my case, text added in the end of PAGE no matter what I used. Eventually I solved this problem by using GetPageText(3) - I just calculate the y-coordinate of the last line. If there is another way to do it, so, would you please.. ^.^

	liveny, The method you have used is the only real method. A PDF file doesn't contain paragraphs and word positions in the way that MS Word would. A PDF is made up of jigsaw pieces and each piece has a location of where it goes on the page. GetPageText finds all the pieces and tries to group them together into words and lines but it is not always perfect as it is not an exact science. For a simple letter it is more than adequate and the only real method to use. Your code might be a little simpler if you use the Text Blocks functions. He is some simple sample code. QP.LoadFromFile("aaa.pdf", ""); for (int i = 1;i<=QP.PageCount();i++) { QP.SelectPage(i); int id = QP.ExtractPageTextBlocks(3); for (int w=1;w<=QP.GetTextBlockCount(id);w++) { double size = QP.GetTextBlockFontSize(id, w); MessageBox.Show("Page :" + i.ToString() + " Word:" + w.ToString() + "'" + QP.GetTextBlockText(id, w) + "'"); } QP.ReleaseTextBlocks(id); } Andrew.
