Description

Some fields disappear when rendered.

b21..b26 fields appear correctly on "3916_2568 filled.pdf", but they are empty on "3916_2568 rendered.pdf".

My code :

package Main;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDDocumentCatalog;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.PDPageContentStream;
import org.apache.pdfbox.pdmodel.common.PDRectangle;
import org.apache.pdfbox.pdmodel.graphics.image.JPEGFactory;
import org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject;
import org.apache.pdfbox.pdmodel.interactive.form.PDAcroForm;
import org.apache.pdfbox.rendering.PDFRenderer;

public class Main {

	public static void main(String[] args) throws IOException {
		PDDocument pdfDoc;
		pdfDoc = PDDocument.load(new File("3916_2568.pdf"));

		pdfDoc.removePage(3);
		pdfDoc.removePage(2);
		pdfDoc.removePage(0);

		PDDocumentCatalog docCatalog = pdfDoc.getDocumentCatalog();

		PDAcroForm form = docCatalog.getAcroForm();

		form.getField("b21").setValue("02");
		form.getField("b22").setValue("03");
		form.getField("b23").setValue("04");
		form.getField("b24").setValue("06");
		form.getField("b25").setValue("07");
		form.getField("b26").setValue("08");

		PDFRenderer renderer = new PDFRenderer(pdfDoc);
		BufferedImage image = renderer.renderImageWithDPI(0, 200);

		float width = image.getWidth();
		float height = image.getHeight();
		PDPage page = new PDPage(new PDRectangle(width, height));
		PDDocument pdfImgDoc = new PDDocument();
		pdfImgDoc.addPage(page);
		PDImageXObject img = JPEGFactory.createFromImage(pdfImgDoc, image);
		PDPageContentStream contentStream = new PDPageContentStream(pdfImgDoc, page);
		contentStream.drawImage(img, 0, 0);
		contentStream.close();

		pdfImgDoc.save(new File("3916_2568 rendered.pdf"));
		pdfImgDoc.close();

		pdfDoc.save(new File("3916_2568 filled.pdf"));
		pdfDoc.close();

	}

}
