Some pdf files, when i open them, i can use the "select text" tool and then copy whatever text i want to my documents -- as text (so that I can edit the words if I want). In other pdf files, when i click the select text tool, it comes up as a small cross, and I can drag it across the pdf text, but the only option is "copy image". When I paste that in my document, it is an image and so I cannot edit the text. Is there some way i can get around this problem without having to get software to convert the whole document to word? and be able to copy the pdf text as text?
