import java.io.FileOutputStream; import java.io.IOException; import com.itextpdf.text.Document; import com.itextpdf.text.DocumentException; import com.itextpdf.text.Image; import com.itextpdf.text.pdf.PdfImportedPage; import com.itextpdf.text.pdf.PdfReader; import com.itextpdf.text.pdf.PdfWriter; public class ReadAndUsePdf { private static String INPUTFILE = "c:/temp/FirstPdf.pdf"; private static String OUTPUTFILE = "c:/temp/ReadPdf.pdf"; public static void main(String[] args) throws DocumentException,IOException { Document document = new Document(); PdfWriter writer = PdfWriter.getInstance(document,new FileOutputStream(OUTPUTFILE)); document.open(); PdfReader reader = new PdfReader(INPUTFILE); int n = reader.getNumberOfPages(); PdfImportedPage page; // Go through all pages for (int i = 1; i <= n; i++) { // Only page number 2 will be included if (i == 2) { page = writer.getImportedPage(reader,i); Image instance = Image.getInstance(page); //how to show this object in a JFrame document.add(instance); } } document.close(); } }
Solution
I have exactly the same problem, I use @ L_ 404_ 2 @ render PDF in swing and operate it through iText to solve it
Can I use iText to render PDF in my swing application?
