Turns a multiple page A4 document into a single PDF.Detects edges of A4 documents (or documents with similar aspect ratio). A picture of the document is automatically taken when the camera is positioned right and held steady. Multiple image pages can then be stored as a single PDF document and (optionally) be sent be email.So far this has been tested on a very limited number of physical devices, so it is provided "as is". I hope you like it.
