How to convert TIFF to PDF with JBIG2 compression from C# source code?

Hi,

We are looking for the SDK capable of converting TIFF to PDF with JBIG2 compression. I have downloaded the PDF OCR Compressor Toolkit (SDK) evaluation, but I cannot see there the code sample that performs the conversion I need. The documentation does not contain the list of possible conversion options, and there is nothing there in sample project besides the "-pidpi 300" .

I will be very grateful if you can send me the code sample that performs the TIFF/PDF conversion similar to what I saw in the test-pdf-jbig2.bat. We are using c# for development.

Thank you in advance,
Customer

You can use " -bwimg 2" parameter to convert a scanned PDF and TIFF file to JBIG2 compressed PDF file, for example,

pdfocrjb2sdk.exe bw.tif bw-pdf-g4.pdf

pdfocrjb2sdk.exe -bwimg 2 bw-pdf-g4.pdf bw-pdf-jbig2.pdf

pdfocrjb2sdk.exe -ocr 1 bw.tif bw-g4-ocr.pdf pdfocrjb2sdk.exe -ocr 1 -bwimg 2 bw.tif bw-jbig2-ocr.pdf

pdfocrjb2sdk.exe -ocr 1 -dpi 300 -skewcorrect -despeckle -chkbwcolor skew_test.tif skew_test-g4-ocr.pdf

pdfocrjb2sdk.exe -ocr 1 -dpi 300 -bwimg 2 -skewcorrect -despeckle -chkbwcolor skew_test.tif skew_test-jbig2-ocr.pdf

I need to do these conversions programmatically; that is why I'm performing the SDK evaluation.

Can you please give me the relevant c# example ?

You can run following command line with administrator privilege to register pdfocrcom.exe first,

pdfocrcom.exe /regserver

after you registered pdfocrcom.exe, you can add a reference to it from your C# project, then you can call "PDFOCRCOM" from your C# code to convert scanned PDF or TIFF file to JBIG2 compressed PDF file by com_PDFOCRCmd() method,

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using PDFOCRCOM;

 

namespace CSharp_COM_Test

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

 

        private void button1_Click(object sender, EventArgs e)

        {

            PDFOCRCOMClass pdfocr = new PDFOCRCOMClass();

            long ret = pdfocr.com_PDFOCRCmd(
                 "-ocr 1 D:\\temp\\test.pdf D:\\temp\\2_out.pdf");

            long ret = pdfocr.com_PDFOCRCmd(
                
"-bwimg 2 D:\\bw-pdf-g4.pdf D:\\bw-pdf-jbig2.pdf");

            long ret = pdfocr.com_PDFOCRCmd(
                
"-ocr 1 -dpi 300 -bwimg 2 -skewcorrect -despeckle
                 -chkbwcolor D:\\skew_test.tif D:\\skew_test-jbig2-ocr.pdf"
);

        }

    }

}

 

After you registered pdfocrcom.exe COM interface, you can compile and run "CSharp_COM_Test" project, you can modify its source code to convert TIFF and PDF files to new JBIG2 compressed PDF file easily.
