I have a JFrame, which i wish to save as a PDF.
How do i paint this JFrame using iText?
public PrintFrameToPDF(JFrame bill) {
try {
Document d = new Document();
PdfWriter writer = PdfWriter.getInstance(d, new FileOutputStream ("sample.pdf"));
d.open ();
// HOW ?
d.close ();
}
catch(Exception e) {
//
}
}
This should do the trick (and it's generic for JComponent object):
public PrintFrameToPDF(JFrame bill) {
try {
Document d = new Document();
PdfWriter writer = PdfWriter.getInstance(d, new FileOutputStream ("sample.pdf"));
d.open ();
PdfContentByte cb = writer.getDirectContent( );
PdfTemplate template = cb.createTemplate(width, height);
Graphics2D g2d = template.createGraphics(width, height);
bill.print(g2d);
bill.addNotify();
bill.validate();
g2d.dispose();
d.close ();
}
catch(Exception e) {
//
}
}

I'm using ItextPdf 5.
I have an SVG file with specifical font (integrated in svg).
When I print my SVG (using batik 1.8) the graphic is print on my document, but fonts are blocked, so, can't select them.
see below my java code :
public class ItextPdfSmallTests {
#Test
public void svgFontsTest() throws IOException, DocumentException, URISyntaxException {
String RESULT = "C:\\test\\svgFontsTest.pdf";
Document document = new Document(PageSize.A4, 36, 36, 54, 36);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(RESULT));
document.open();
document.add(new Paragraph("SVG Example"));
int width = 250;
int height = 250;
PdfContentByte cb = writer.getDirectContent();
PdfTemplate template = cb.createTemplate(width, height);
PdfPrinterGraphics2D g2 = new PdfPrinterGraphics2D(cb, width, height, new MyFontMapper(), PrinterJob.getPrinterJob());
PrintTranscoder prm = new PrintTranscoder();
URI svgFileURI = getClass().getResource("myfont.svg").toURI();
TranscoderInput ti = new TranscoderInput(svgFileURI.toString());
prm.transcode(ti, null);
PageFormat pg = new PageFormat();
Paper pp = new Paper();
pp.setSize(width, height);
pp.setImageableArea(0, 0, width, height);
pg.setPaper(pp);
prm.print(g2, pg, 0);
g2.dispose();
ImgTemplate img = new ImgTemplate(template);
document.add(img);
document.close();
}
class MyFontMapper extends DefaultFontMapper {
#Override
public BaseFont awtToPdf(java.awt.Font font) {
try {
return BaseFont.createFont("AmaticSC-Regular.ttf", BaseFont.WINANSI, false);
} catch (DocumentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
}
is it possible make it editable ?
thanks for your helps
We use the nice library iText for one of my customer's project to generate a pdf from a string representing a html page. The iText version is 5.5.10.
The following piece of code works well on the development environments and servers running on Windows, but it is not working on the customer's server running on iSeries.
public class GeneratePDFCmdImpl extends ControllerCommandImpl implements
GeneratePDFCmd {
private String charsetStr = null;
private Charset charset = null;
private BaseFont bf = null;
private String destFile = null;
private String destFilename = null;
private String srcContent = null;
private String docName = null;
public void setDocName(String docname) {
this.docName = docname;
}
public void setSrcContent(String srcContent) {
this.srcContent = srcContent;
}
private void prepareDefaultsAndSettings() {
/* srcContent may be more complex html but even this simple one is not working */
srcContent = "<html><head></head><body>This is just a test</body></html>";
docName = "mypdf";
charsetStr = "UTF-8";
destFilename = docName+".pdf";
Date timestamp = new Date();
/* destFile = "/" is just for the sample. In my real project, the value is a folder where my app has full rights
*/
destFile = "/" + destFilename;
charset = Charset.forName(charsetStr);
FontFactory.register("/fonts/arial.ttf","Arial");
bf = FontFactory.getFont("Arial").getBaseFont();
}
#Override
public void performExecute() throws ECException {
super.performExecute();
Document document = null;
OutputStream os = null;
prepareDefaultsAndSettings();
try {
InputStream srcInputStream;
srcInputStream = new ByteArrayInputStream(srcContent.getBytes(charset));
document = new Document(PageSize.A4, 20, 20, 75, 80);
FileOutputStream destOutput = new FileOutputStream(destFile);
PdfWriter writer = PdfWriter.getInstance(document,destOutput);
writer.setPageEvent( new HeaderFooterPageEvent(bf));
document.open();
XMLWorkerHelper.getInstance().parseXHtml(writer, document, srcInputStream, charset);
document.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
} finally {
if(document != null) {
document.close();
}
document = null;
try {
if (os != null) {
os.close();
}
} catch(IOException e) {
e.printStackTrace();
}
os = null;
}
}
private class HeaderFooterPageEvent extends PdfPageEventHelper {
PdfContentByte cb;
PdfTemplate template;
BaseFont bf;
Font f;
float fs;
public HeaderFooterPageEvent(BaseFont _bf) {
super();
bf = _bf;
f = new Font(bf);
}
#Override
public void onOpenDocument(PdfWriter writer, Document document) {
cb = writer.getDirectContent();
template = cb.createTemplate(50, 50);
}
#Override
public void onEndPage(PdfWriter writer, Document document) {
Date dat = new Date();
ColumnText ct = new ColumnText(writer.getDirectContent());
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm");
ct.showTextAligned(writer.getDirectContent(), Element.ALIGN_CENTER, new Phrase(sdf.format(dat) ), 100, 30, 0);
String text = "Page " +writer.getPageNumber() + " to ";
float len = bf.getWidthPoint(text, 12);
cb.beginText();
cb.setFontAndSize(bf, 12);
cb.setTextMatrix(450, 30);
cb.showText(text);
cb.endText();
cb.addTemplate(template, 450 + len, 30);
}
#Override
public void onCloseDocument(PdfWriter writer, Document document) {
template.beginText();
template.setFontAndSize(bf, 12);
template.showText(String.valueOf(writer.getPageNumber()));
template.endText();
}
}
}
When executed on the iSeries, we have the error message
com.ibm.commerce.command.ECCommandTarget executeCommand CMN0420E: The following command exception has occurred during processing: "ExceptionConverter: java.io.IOException: The document has no pages.". ExceptionConverter: java.io.IOException: The document has no pages.

I don't have much idea about what we do wrong. Any help would be greatly appreciated
I am using Flying Saucer library to convert html to pdf. It is working fine with the all the HTML files.
But for some HTML files which include some tags in pre tag, generated PDF file has tags displayed.
If I remove pre tags then the formatting of data is lost.
My code is
org.w3c.dom.Document document = null;
try {
Document doc = Jsoup.parse(new File(htmlFile), "UTF-8", "");
Whitelist wl = new RelaxedPlusDataBase64Images();
Cleaner cleaner = new Cleaner(wl);
doc = cleaner.clean(doc);
Tidy tidy = new Tidy();
tidy.setShowWarnings(false);
tidy.setXmlTags(false);
tidy.setInputEncoding("UTF-8");
tidy.setOutputEncoding("UTF-8");
tidy.setPrintBodyOnly(true);
tidy.setXHTML(true);
tidy.setMakeClean(true);
tidy.setAsciiChars(true);
if (doc.select("pre").html().contains("</")) {
doc.select("pre").unwrap();
}
Reader reader = new StringReader(doc.html());
document = (tidy.parseDOM(reader, null));
Element element = (Element) document.getElementsByTagName("head").item(0);
element.getParentNode().removeChild(element);
NodeList elements = document.getElementsByTagName("img");
for (int i = 0; i < elements.getLength(); i++) {
String value = elements.item(i).getAttributes().getNamedItem("src").getNodeValue();
if (value != null && value.startsWith("cid:") && value.contains("#")) {
value = value.substring(value.indexOf("cid:") + 4, value.indexOf("#"));
elements.item(i).getAttributes().getNamedItem("src").setNodeValue(value);
System.out.println(value);
}
}
document.normalize();
System.out.println(getNiceLyFormattedXMLDocument(document));
} catch (Exception e) {
System.out.println(e);
}
Method to create PDF is :
try {
org.w3c.dom.Document doc = CleanHtml.cleanNTidyHTML("b.html");
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
renderer.setPDFVersion(new Character('7'));
String outputFile = "test.pdf";
OutputStream os = new FileOutputStream(outputFile);
renderer.layout();
renderer.createPDF(os);
os.flush();
os.close();
} catch (Exception e) {
e.printStackTrace();
}
By using itext XMLWorker :
try {
org.w3c.dom.Document doc = CleanHtml.cleanNTidyHTML("a.html");
String k = CleanHtml.getNiceLyFormattedXMLDocument(doc);
OutputStream file = new FileOutputStream(new File("test.pdf"));
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
ByteArrayInputStream is = new ByteArrayInputStream(k.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
}
public static String getNiceLyFormattedXMLDocument(org.w3c.dom.Document doc) throws IOException, TransformerException {
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
// transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
Writer stringWriter = new StringWriter();
StreamResult streamResult = new StreamResult(stringWriter);
transformer.transform(new DOMSource(doc), streamResult);
String result = stringWriter.toString();
return result;
}
I have a pdf, but beyond the current page, there is content that is not being displayed. I want to change the pagesize so that all of the content can be displayed. Is there a way to do this with itext?
public PdfReader changePDFPageSize(String inpdf,String outpdf,float vertical,float horizontal)
{
try
{
PdfReader reader = new PdfReader(inpdf);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(outpdf));
for (int curPageNum = 1; curPageNum <= reader.getNumberOfPages(); ++curPageNum) {
PdfDictionary pagedict = reader.getPageN(curPageNum);
PdfArray mediabox = pagedict.getAsArray(PdfName.MEDIABOX);
mediabox.set(0, new PdfNumber(mediabox.getAsNumber(0).intValue()-horizontal));//left add
mediabox.set(1, new PdfNumber(mediabox.getAsNumber(1).intValue()-vertical));//down
mediabox.set(2, new PdfNumber(mediabox.getAsNumber(2).intValue()+horizontal));//right
mediabox.set(3, new PdfNumber(mediabox.getAsNumber(3).intValue()+vertical));//up
}
stamper.close();
return new PdfReader(outpdf);
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (DocumentException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
return null;
}
itextsharp VB.NET
Dim objReader As PdfReader
Dim objStream As FileStream
Dim objStamper As PdfStamper
Dim objContent As PdfContentByte
Dim objImport As PdfImportedPage
Dim objMark As Image
objReader = New PdfReader(strBookPath)
objStream = New FileStream(strTempPath, FileMode.Create)
objStamper = New PdfStamper(objReader, objStream)

objContent.AddTemplate(objImport, PageSize.A4.Width / objImport.Width, 0, 0, PageSize.A4.Height / objImport.Height, 0, 0)
objReader.GetPageN(1).Put(PdfName.CROPBOX, New PdfRectangle(PageSize.A4.Width, PageSize.A4.Height))

I am trying to download and merges multiple pdf files by using ITextSharp.
It used to working before but I being got an "Content can not be added to a PdfImportedPage." error message on the line:
importedPage = writer.GetImportedPage(reader, currentPageIndex);
The full code is below, any help will be very appreciated.
private string MergeDocuments(IList<string> fileUrls, string fileName)
{
var reportFolder = this.ReportFolder + "\\";
using (MemoryStream output = new MemoryStream())
{
Document document = new Document();
try
{
// Initialize pdf writer
PdfWriter writer = PdfWriter.GetInstance(document, output);
// Open document to write
document.Open();
PdfContentByte content = writer.DirectContent;
PdfImportedPage importedPage;
// Iterate through all pdf documents
foreach (var url in fileUrls)
{
// Create pdf reader
using (PdfReader reader = new PdfReader(new Uri(url)))
{
int numberOfPages = reader.NumberOfPages;
// Iterate through all pages
for (int currentPageIndex = 1; currentPageIndex <= numberOfPages; currentPageIndex++)
{
// Determine page size for the current page
document.SetPageSize( reader.GetPageSizeWithRotation(currentPageIndex) );
// Create page
document.NewPage();
importedPage = writer.GetImportedPage(reader, currentPageIndex);
content.AddTemplate(importedPage, 1f, 0, 0, 1f, 0, 0);
}
}
}
}
catch (Exception exception)
{
throw new Exception("Error occured", exception);
}
File.WriteAllBytes(reportFolder + fileName + ".pdf", output.GetBuffer());
}
return "Reports/" + fileName + ".pdf";
}
When I try the following code, I get a null pointer exception in the addDocument() method:
using (MemoryStream output = new MemoryStream()) {
Document document = new Document();
document.Open();
PdfCopy copy = new PdfSmartCopy(document, output);
foreach (var url in fileUrls) {
using (WebClient client = new WebClient()) {
var byteArray = client.DownloadData(url);
PdfReader reader = new PdfReader(byteArray);
copy.AddDocument(reader);
reader.Close();
}
}
}
I found the problem, the document object should be closed before writing memory stream to file.
Just added document.Close() as below.
document.Close();
File.WriteAllBytes(reportFolder + fileName + ".pdf", output.GetBuffer());
