Scanning Documents
This is just a quick note about scanning documents.
In recent day this has come up several times.
It seems that it would be easy and natural to take a written document into a computer and then add to or change some of the text.
I have people come in and want me to scan a written document and put it on a disk so that they can make changes in Word.
However, when a document is scanned it becomes an image, just like a photo.
It is not a live document.
One could attach it to an e-mail and send it to someone just as they would a photo.
The recipient could read it and even reply to it.
However, if he wants to open it in a word processor and make changes, it has to be converted to a “live” document.
This is done with OCR (optical character recognition) software, which has to look at the image and figure out how to change it into text.
This is not as easy as it sounds because there are many different font types, font sizes and page formats which have to be recognized.
OCR software has come a long way and is amazingly accurate, but the document would still have to be read carefully for errors because there likely will be some.
Therefore, always remember that a scanner creates an image.
In order to make the image into “live” text it will have to first be manipulated by an OCR program.
