Re: Especial Characteres
Dmitry, I fully agree with your points. Newbies (who are non-programmer) like me cannot make traineddata file without any valuable guidance of people like you. Being expert programmer/developer, you have succeeded to build traineddata very easily. As such only newbies need/must to refer to the forum discussion on any points -for solution, With Warmest regards, -sriranga(78yrs) On Thu, Mar 3, 2011 at 7:46 PM, Dmitry Silaev daemons2...@gmail.com wrote: Sriranga, Actually I don't understand why one needs to refer to the forum discussion you've just mentioned above, as I managed to build this traineddata file without writing a single line of code and even without a compiler, say Visual C++... The value I can add is in that any user inexperienced in programming can make this traineddata file himself )) Warm regards, Dmitry Silaev On Thu, Mar 3, 2011 at 5:08 PM, Sriranga(78yrsold) withblessi...@gmail.com wrote: Dmitry, No I am NOT the first invented but actually credited to spohor...@sjm.com -who helped me very lot including creating vcproj for combined traineddata for windows. I am very thankful to him for his help/guidance rendered from time to time. Without his help I would not succeeded to generate traineddata file out of old datafiles All credits should go to Steve. Steve has already explained in detail how to do in the forum discussion are available. -sriranga(78yrs) On Thu, Mar 3, 2011 at 6:36 PM, Dmitry Silaev daemons2...@gmail.com wrote: Sriranga, Thanks for letting me know.

Re: Especial Characteres
Hi Dmitry, I just replaced with your file por.traineddata But I'm getting an error: manuel$ tesseract input.tiff output -l por actual_tessdata_num_entries_ = TESSDATA_NUM_ENTRIES:Error:Assert failed:in file tessdatamanager.cpp, line 55 Segmentation fault It's seem to be interesting to convert old files from 2.0X to 3, because there isn't a brazillian portuguese for version 3, just portuguese. At least the dictionary por.traineeddata is working correctly in version 3. The special chars is being recognized by tesseract 3. regards, Manuel Pardo Em 03/03/2011, às 09:12, Dmitry Silaev escreveu: Manuel, It's quite an interesting question although it may seem to be an ordinary newbie-like one.

Re: Especial Characteres
Manuel, Is the error message generated by version 2.xx? Did you try to run version 3.xx with my por.traineddata file? I don't get it - have you succeeded or not? Please provide us with the image you are trying to recognize.
