Hi Zdenko, very good job! i've tried so many image manipulation, but this was the wrong way for the problems 1-3. the idea with the uzn file is great and i think the perfect solution. Thanks :-)
i can confirm that scaling these image doesn't helped (more than 30 pixel per letter is the right explanation). what do you mean with the "end" traineddata? i have the "eng" traineddata and can't find "end.traineddata" - neither on google. i've tested it your files and the result is perfect. thank you, thank you, thank you!
