Thank you a lot for your prompt answer ! I really appreciate that ! I have run in cmd line: tesseract --help-extra, I don't spot any graphic library option.
I have to tell you that I am using Windows10, and I have compiled leptonica with VS2017, taken from here: https://github.com/danbloomberg/leptonica I have generate a .sln file with CMake, but I get some warnings there: Could NOT find GIF (missing: GIF_LIBRARY GIF_INCLUDE_DIR) Could NOT find JPEG (missing: JPEG_LIBRARY JPEG_INCLUDE_DIR) Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR) Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR) Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR) Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR) Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) which tell me that I haven't some libraries, but I really don't know how to achieve them ...
