I have a simple HTML page, iText is able to produce a PDF from it. It's fine but the checkbox is ignored. What can I do about it ?
import java.io.FileOutputStream;
import java.io.StringReader;
import com.itextpdf.text.Document;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.html.simpleparser.HTMLWorker;
import com.itextpdf.text.pdf.PdfWriter;
public class HtmlToPDF {
public static void main(String ... args ) {
try {
Document document = new Document(PageSize.LETTER);
PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream("c://temp//testpdf.pdf"));
document.open();
String str = "<HTML><HEAD></HEAD><BODY><H1>Testing</H1><FORM>" +
"check : <INPUT TYPE='checkbox' CHECKED/><br/>" +
"</FORM></BODY></HTML>";
htmlWorker.parse(new StringReader(str));
document.close();
System.out.println("Done.");
}
catch (Exception e) {
e.printStackTrace();
}
}
}
I got it working with YAHP ( http://www.allcolor.org/YaHPConverter/ ).
import java.io.File;
import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
// http://www.allcolor.org/YaHPConverter/
import org.allcolor.yahp.converter.CYaHPConverter;
import org.allcolor.yahp.converter.IHtmlToPdfTransformer;
public class HtmlToPdf_yahp {
public static void main(String ... args ) throws Exception {
htmlToPdfFile();
}
public static void htmlToPdfFile() throws Exception {
CYaHPConverter converter = new CYaHPConverter();
File fout = new File("c:/temp/x.pdf");
FileOutputStream out = new FileOutputStream(fout);
Map properties = new HashMap();
List headerFooterList = new ArrayList();
String str = "<HTML><HEAD></HEAD><BODY><H1>Testing</H1><FORM>" +
"check : <INPUT TYPE='checkbox' checked=checked/><br/>" +
"</FORM></BODY></HTML>";
properties.put(IHtmlToPdfTransformer.PDF_RENDERER_CLASS,
IHtmlToPdfTransformer.FLYINGSAUCER_PDF_RENDERER);
//properties.put(IHtmlToPdfTransformer.FOP_TTF_FONT_PATH, fontPath);
converter.convertToPdf(str,
IHtmlToPdfTransformer.A4P, headerFooterList, "file://c:/temp/", out,
properties);
out.flush();
out.close();
}
}

Are you generating the HTML?
If so, then instead of using an HTML checkbox you could using the Unicode 'ballot box' character, which is ☐ or ☐. It's just a box, you can't electronically tick it or untick it; but if the PDF is intended for printing then of course people can tick it using a pen or pencil.
For example:
String str = "<HTML><HEAD></HEAD><BODY><H1>Testing</H1><FORM>" +
"check : ☐<br/>" +
"</FORM></BODY></HTML>";
Note that this will only work if you're using a Unicode font in your PDF; I think that iText won't use a Unicode font unless you tell it to.
