Scanning Documents

If you have a scanner, you can scan documents in Linux. You can scan two types of documents:

• Images :
  A document is scanned and stored in a graphics file format. The image must be viewed with software that can display graphics. The image is a picture of the document.

• Text :
  A document that contains text can be converted into a text document. Using a process called optical character recognition (OCR), the characters that are scanned are read as letters and stored in a text file. OCR doesn't get the characters 100% correct. Its accuracy depends on the quality of the document being scanned. However, if you need to edit a document, it's often faster to scan it and edit the OCR errors than to type the document from scratch.

Scanning on Linux is provided via Kooka, an open source raster image scan program that is an official part of the KDE Graphics Package. Kooka uses the SANE (Scanner Access Now Easy) library. Kooka provides OCR, as well as scanning documents in image format.Chapter 10 for information on installing packages.Chapter 18. Kate can be used to edit the file if necessary, including checking the file with the spell checker, useful for finding the OCR errors in the file. You can save the file from Kate as a text file. You can then open it in any text editor or word processor for further use or editing.
