Hi Sventech, I've tested the image with the command line version and I get the same result as you. But when I use my own software in C++ I cannot obtain the same result, simply get nothing. Currently I am using PSM_SINGLE_LINE, but I've said before I've tried all the page seg modes. I don't know what is wrong. I've reinstalled tesseract and do the same.
