While specifiing the language pack used to perform the OCR, i get the following error (for every language pack corresponding):
read_params_file: Can't open deu
I used the command as described in the wiki:
tesseract test.tif out -1 deu
The .traineddata files are located under tessdata and the TESSDATA_PREFIX is set to the parent directory of tessdata. The process works under default without given language information.
I have Tesseract 3.05 installed on Windows 10.
The command should be
tesseract test.tif out -l deu
with "l" instead of a "1".
