I did not experienced problem with tiff on my Windows XP. I have no possibility to test it on Win 7. Anyway I plan to use leptonica to import images (at leastfor tiff ;-) ) - this would bring also multipage tiff support, but I have not time for this development (you know it works for me at this stage, and there is bunch of other tasks...)

Import feature is quite simple: 1. QBE expects that number of boxes (already in table view) is equal to number of symbols excluding spaces and linebreaks (\n). Otherwise you got error (there are more symbol than boxes, or there are more boxes than symbol). 2. QBE expects for import format: one box = one symbol 2. It seems from the little reading of the source that I have done, that > there is an option for box files which handle a line at a time and segment > at word level. Is there some feature like that? It is not clear to me, what do you need (or expect): tesseract box file can have one box per line. There is no information about words. QBE offer export where it try to identify words based on space between boxes (6pt - this can be adjusted in settings) It is not perfect, but it works in most of situation (problem could be on historical documents with non consistent spacing) > Can it be used with QT Box editor? > > Generally: QBE was based for my needs (latin based script - so have no clue, how it behaves in other scripts).
