how to set tessedit_create_hocr 1 tessedit_pageseg_mode 4 in TesseractOCR

[pjoshi90]

i want to set below hocr setting witj TessractOcr tessedit_create_hocr 1tessedit_pageseg_mode 4

you can find hocr file which we can placed inside tessdata folder hocr.txt

You can set all these mode through code. You don't have to place this inside the tessdata folder.

First create the engine with the constructor

        /// <summary>
        ///     Creates a new instance of <see cref="Engine" /> with the specified <paramref name="engineMode" /> and
        ///     <paramref name="configFiles" />.
        /// </summary>
        /// <remarks>
        ///     <para>
        ///         The <paramref name="dataPath" /> parameter should point to the directory that contains the 'tessdata' folder
        ///         for example if your tesseract language data is installed in <c>C:\Tesseract\tessdata</c> the value of datapath
        ///         should
        ///         be <c>C:\Tesseract</c>. Note that tesseract will use the value of the <c>TESSDATA_PREFIX</c> environment
        ///         variable if defined,
        ///         effectively ignoring the value of <paramref name="dataPath" /> parameter.
        ///     </para>
        /// </remarks>
        /// <param name="dataPath">
        ///     The path to the parent directory that contains the 'tessdata' directory, ignored if the
        ///     <c>TESSDATA_PREFIX</c> environment variable is defined.
        /// </param>
        /// <param name="language">The <see cref="Language"/> to load</param>
        /// <param name="engineMode">The <see cref="EngineMode" /> value to use when initializing the tesseract engine</param>
        /// <param name="configFiles">
        ///     An optional sequence of tesseract configuration files to load, encoded using UTF8 without BOM
        ///     with Unix end of line characters you can use an advanced text editor such as Notepad++ to accomplish this.
        /// </param>
        /// <param name="initialOptions"></param>
        /// <param name="setOnlyNonDebugVariables"></param>
        /// <param name="logger">When set then logging is written to this <see cref="ILogger"/> interface</param>
        public Engine(string dataPath, Language language, EngineMode engineMode = EngineMode.Default, IEnumerable<string> configFiles = null, IDictionary<string, object> initialOptions = null, bool setOnlyNonDebugVariables = false, ILogger logger = null)
        {
            if (logger != null)
                Logger.LoggerInterface = logger;

            DefaultPageSegMode = PageSegMode.Auto;
            _handle = new HandleRef(this, TessApi.Native.BaseApiCreate());

            Initialize(dataPath, new List<Language> {language}, engineMode, configFiles, initialOptions, setOnlyNonDebugVariables, logger);
        }

After that you can set the page seg mode

        /// <summary>
        ///     Processes the specific image.
        /// </summary>
        /// <remarks>
        ///     You can only have one result iterator open at any one time.
        /// </remarks>
        /// <param name="image">The image to process.</param>
        /// <param name="inputName">Sets the input file's name, only needed for training or loading a uzn file.</param>
        /// <param name="pageSegMode">The page layout analysis method to use.</param>
        public Page Process(Pix.Image image, string inputName, PageSegMode? pageSegMode = null)
        {
            return Process(image, inputName, new Rect(0, 0, image.Width, image.Height), pageSegMode);
        }
