As a teacher, I have used it from time to time for when I want to show a document or article on the interactive whiteboard (such as newspaper articles or pupils' work). So I just take a picture of the document, then project it using the VGA adaptor.
The photo turns out pretty well. Now if only there were some way to annotate on photos...![]()
Try Adobe Ideas - I it might be free (can't recall)
Try a scanner app such as Scanner Pro. You can export as a PDF and annotate in one of the PDF annotation apps such as PDF Expert.
