How can I copy and paste material from a .pdf document into Google language tool?

I have several articles in German which I have scanned from books and which are in .pdf format. I would like to copy and paste some blocks of the text into an online translation tool like Google but I don't seem to be able to do that directly. Is there a way of doing this? It will save me a lot of long-handed copying.|||above the document ther is signed many letters ok just click edit then click copy or paste!
