How to read checkbox on a paper

Question asked by dranakan on Sep 27, 2010

I would like to be able to know if a checkbox is selected on a paper.

1) There is a checkbox on a paper (precise position), a user writes a cross inside (or not)
2) The paper is scanned in PDF
3) I can start an action in Alfresco but after I don't know how can I know if the ckeckbox if selected…
4) …

How can I do that ?

For the moment I can zoom on the checkbox (I create a new PDF with the position (itext)). I also can convert into picture. Do I use an API able to give the percentage of white and black ? (if there is more black… the checkbox is selected…)
