While researching your family tree, you will find textual publications or administrative documents. You may avoid long and annoying work into GRAMPS by using optical character recognition ([http://en.wikipedia.org/wiki/Optical_character_recognition OCR]).
Here we show how you can work on your picture to make it to text !!!
==How this work ?==
* picture need to be contrastedwith a good resolution
* OCR programs read the picture and with forms librairies, detect the characters in order to make some correspond the form to the awaited character
* dictionnaries will be used for minimized errors. They make comparison between existing words and your result.
There is not a lot of OCR open sources programs.
Intelligent Word Recognition (IWR), [http://en.wikipedia.org/wiki/Intelligent_Character_Recognition Intelligent Character Recognition (ICR) ] for written certificates are hight level. They are used on financial, historical sectors. Some programs may be used as third party of GRAMPS. ''-h'' on command line for output options.
* [http://code.google.com/p/tesseract-ocr/ Tesseract] may be a good solution for english reader but it currently only recognizes US-ASCII characters ...
* [http://www.geocities.com/claraocr/ claraocr] seems to be able to learn but I do not find any documentation. Also, need to use pgm or pbm file format.
