When saving them in text file, you can also add various page number to text file. When operation, you do not need to open input raster image file as the conversion could be done by from MS Dos Windows by command line.

   The method could be fulfilled under the help of software VeryDOC Raster to Text OCR Converter Command Line, which is a professional tool of converting raster image file to text. In the following part, I will show you how to use this software.

    By this command line, we can extract text from tiff raster image file. And even if there are many pages in tiff, the extraction could be done fast and accurately.
    pdf2txtocr.exe C:\in.jpg C:\out.txt
    Same with the above command line, by it we can extract text from JPG raster image file.
