Sample Code: Formatted Document Conversion (OneStep)

Article # 3016917 - Page views: 870

How do you convert an image document to a searchable format?

The sample function below will take as input the path to an image file as well as the path where the output document should be placed. This code utilizes OmniPage SDK's "OneStep" workflow to load the input document, OCR it and export the output to a formatted file in a single function call.

References needed:



private static void FormattedOneStep(string inputFile, string outputFile)


    //Initialize the engine and enable formatted output

    Engine.Init("CompanyName", "ProductName", true);

    //Create a settings collection to manage OCR settings

    using (SettingCollection settings = new SettingCollection())


        //Set the recognition module to our 3-way engine which is the most accurate

        settings.DefaultRecognitionModule = RECOGNITIONMODULE.RM_OMNIFONT_PLUS3W;

        //Set the output format to searchable PDF                

        settings.OutputFormats.Current = "Converters.Text.PDFImageOnText";

        //Other common outputs:

        //Text - "Converters.Text.Text

        //Word Document - "Converters.Text.DOCX"

        //XML - "Converters.Text.XML"

        //HTML - "Converters.Text.Html40

        //Perform "one-step" document conversion

        settings.ProcessPages(outputFile, new string[] { inputFile });
