Hy Martyn,
thank's for your quick responce. With your help and a little bit time i have made my first own extract module.
I scan documents and archive it to a djvu sandwich which contain the text informations from ocr in a hidden layer.
In my modul i read out that textinformatons (i use the djvulibre lib) an store that informations in the tracker db.
regards Matthias
