I need to convert an image to PDF file in my Android application but i found two library iTextG and iText. Are they open source?

YES, iText is an open source library. Infomation from itext oficial site: "iText is a free/open source software (F/OSS) project, giving you a lot of freedom and flexibility.... You have to respect the Affero General Public License (AGPL)."

and you can use it like that:

import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.text.Image;


public class ImageToPDF {
  public static void main(String ... args) {
    Document document = new Document();
    String input = "c:/temp/capture.png"; // .gif and .jpg are ok too!
    String output = "c:/temp/capture.pdf";
    try {
      FileOutputStream fos = new FileOutputStream(output);
      PdfWriter writer = PdfWriter.getInstance(document, fos);
      writer.open();
      document.open();
      document.add(Image.getInstance(input));
      document.close();
      writer.close();
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }
}
