I can successfully generate a pdf from an html string, but the problem is that it doesn't take the css script. How can I generate the pdf with css style?
Please help! I have tried cssresolver als
My code is here:
{String result = "failed";
try
{
String html2 ="<html>"+.....+"</html>" ;
long timemilli = System.currentTimeMillis();
String filename = "EastAfriPack2014_Ticket_"+timemilli;
String writePath = Global.PDF_SAVE_PATH + filename ;
System.out.println("----------writePath--------------"+ writePath);
OutputStream file = new FileOutputStream(new File(writePath+".pdf"));
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
InputStream is = new ByteArrayInputStream(k.getBytes());
CSSResolver cssResolver = XMLWorkerHelper.getInstance().getDefaultCssResolver(false);
cssResolver.addCss("table {color: red; background-color: blue; } ", true);
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
file.close();
System.out.println("pdf created");
result = filename;
return filename;
} catch (Exception e) {
e.printStackTrace();
return result;
}
}
I don't think your approach works. I tried it before because, its the easiest way to create a PDF from HTML, but got bitten by same problem.
You either provide the styles inline via style attribute for the table
or
use the HTML, CSS files separately and send them to the HelperClass
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new FileInputStream("myhtmlFile.html"),
new FileInputStream("myCSSFile.css"));
the HTML part can also be an inputStream you made above in the code.

Hi i am using iText & XMLWorker for HTML to pdf Conversion (Java) as below
public void convertHtmlToPdf(StringBuilder content, String path) throws Exception {
String methodName = "convertHtmlToPdf";
try {
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("C:/Users/Aaryan/Downloads/arial.ttf");
final OutputStream file = new FileOutputStream(new File(path));
final Document document = new Document();
final PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
final TagProcessorFactory tagProcessorFactory = Tags.getHtmlTagProcessorFactory();
tagProcessorFactory.removeProcessor(HTML.Tag.IMG);
tagProcessorFactory.addProcessor(new ImageTagProcessor(), HTML.Tag.IMG);
final CssFilesImpl cssFiles = new CssFilesImpl();
cssFiles.add(XMLWorkerHelper.getInstance().getDefaultCSS());
final StyleAttrCSSResolver cssResolver = new StyleAttrCSSResolver(cssFiles);
final HtmlPipelineContext hpc = new HtmlPipelineContext(new CssAppliersImpl(fontProvider));
hpc.setAcceptUnknown(true).autoBookmark(true).setTagFactory(tagProcessorFactory);
final HtmlPipeline htmlPipeline = new HtmlPipeline(hpc, new PdfWriterPipeline(document, writer));
final Pipeline<?> pipeline = new CssResolverPipeline(cssResolver, htmlPipeline);
final XMLWorker worker = new XMLWorker(pipeline, true);
final Charset charset = Charset.forName("UTF-8");
final XMLParser xmlParser = new XMLParser(true, worker, charset);
InputStream is2 = new ByteArrayInputStream(content.toString().getBytes());
xmlParser.parse(is2, charset);
is2.close();
document.close();
file.close();
} catch (Exception ex) {
System.out.println("Exception in Class::" + className + "::Method::" + methodName + "::" + ex.getMessage());
ex.printStackTrace();
throw new Exception(ex);
}
}
PDFGeneration works Fine. The HTML content parsed for pdfConversion has special characters as appropiate entities as below
StringBuilder content = new StringBuilder();
content.append("<html><body style=\"font-size:12.0pt; font-family:Arial\">
<p>Testes → → Vasa efferentia → Kidney → Seminal Vescile</p></body></html>");
The Generated pdf displays '?' instead appropiate special characters (arrow symbols) . "Testes ?? Vasa efferentia ? Kidney ? Seminal Vescile ". Where am i going wrong. Please guide me on this.
The solution has almost nothing to do with the code/classes/objects...
You need to set the CSS "font-family" with something matching your requested output char-set
for example, if you have your special characters inside the 'p' html tag, then you can set the below style with desired font-family:
<HEAD>
<style>
p {
font-family: -good-font-family-
}
</style>
</HEAD>

Does anyone know how image file can be easily converted into PDF format. What I need is to get the image from database and display it on the screen as PDF. What am I doing wrong? I tried to use iText but with no results.
My code:
StreamResource resource = file.downloadFromDatabase();//get file from db
Document converToPdf=new Document();//Create Document Object
PdfWriter.getInstance(convertToPdf, new FileOutputStream(""));//Create PdfWriter for Document to hold physical file
convertToPdf.open();
Image convertJpg=Image.getInstance(resource); //Get the input image to Convert to PDF
convertToPdf.add(convertJpg);//Add image to Document
Embedded pdf = new Embedded("", convertToPdf);//display document
pdf.setMimeType("application/pdf");
pdf.setType(Embedded.TYPE_BROWSER);
pdf.setSizeFull();
Thanks.
You're not using iText correctly:
You never close your writer, so the addition of the image never gets written to the outputstream.
You pass an empty string to your FileOutputStream. If you want to keep the pdf in memory, use a ByteArrayOutputStream. If not, define a temporary name instead.
You pass your Document object, which is a iText-specific object to your Embedded object and treat it like a file. It is not a pdf-file or byte[]. You'll probably want to pass either your ByteArrayOutputStream or read the temp file as a ByteArrayOutputStream into memory and pass that to Embedded.
Maybe someone will use (Vaadin + iText)
Button but = new Button("FV");
StreamResource myResource = getPDFStream();
FileDownloader fileDownloader = new FileDownloader(myResource);
fileDownloader.extend(but);
hboxBottom.addComponent( but );
private StreamResource getPDFStream() {
StreamResource.StreamSource source = new StreamResource.StreamSource() {
public InputStream getStream() {
// step 1
com.itextpdf.text.Document document = new com.itextpdf.text.Document();
// step 2
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
com.itextpdf.text.pdf.PdfWriter.getInstance(document, baos);
// step 3
document.open();
document.add(Chunk.NEWLINE); //Something like in HTML :-)
document.add(new Paragraph("TEST" ));
document.add(Chunk.NEWLINE); //Something like in HTML :-)
document.newPage(); //Opened new page
//document.add(list); //In the new page we are going to add list
document.close();
//file.close();
System.out.println("Pdf created successfully..");
} catch (DocumentException ex) {
Logger.getLogger(WndOrderZwd.class.getName()).log(Level.SEVERE, null, ex);
}
ByteArrayOutputStream stream = baos;
InputStream input = new ByteArrayInputStream(stream.toByteArray());
return input;
}
};
StreamResource resource = new StreamResource ( source, "test.pdf" );
return resource;
}
I'm executing this code from Eclipse and on Tomcat into a webapp
FileInputStream is = new FileInputStream("C:/Users/admin/Desktop/dummy.txt");
try {
FontFactory.register("C:/Workspace/Osmosit/ReportManager/testSvn/ReportManagerCommon/src/main/java/com/osmosit/reportmanager/common/itext/fonts/ARIALUNI.TTF");
} catch (Exception e) {
e.printStackTrace();
}
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(1024);
Document document = new Document(PageSize.A4);
PdfWriter writer;
writer = PdfWriter.getInstance(document, byteArrayOutputStream);
document.open();
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
byteArrayOutputStream.close();
FileOutputStream fos = new FileOutputStream("C:/Users/admin/Desktop/prova-web.pdf");
fos.write(byteArrayOutputStream.toByteArray());
fos.close();
the dummy.txt is a simple html with aranic and latin characters
<div style="font-family: Arial Unicode MS;" ><p>كما. أي مدن العدّ وقام test latin</p><br /></div>
When I run under eclipse I obtain a correct pd, when it runs on Tomcat I get this:
كما. أي مدن العدّ وقام test latin
PS: I'm using itextpdf ver 5.5.8
You have an encoding problem. Either you saved dummy.txt using the wrong encoding (e.g. as Latin-1 instead of as UTF-8), or you are reading dummy.txt using the wrong encoding.
See html to pdf convert, cyrillic characters not displayed properly and adapt the line in which you use parseHtml():
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
is, null, Charset.forName("UTF-8"), fontImp);
Take a look at the ParseHtml11 example to find out what fontImp is about.
You are also making another mistake: Arabic is read from right to left, and in your code, you aren't defining the run direction. See Arabic characters from html content to pdf using iText
In your case, I would put the Arabic text in a table and I would follow the ParseHtml7 example from the official documentation:
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
// Styles
CSSResolver cssResolver = new StyleAttrCSSResolver();
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("resources/fonts/NotoNaskhArabic-Regular.ttf");
CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
// HTML
HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
// Pipelines
ElementList elements = new ElementList();
ElementHandlerPipeline pdf = new ElementHandlerPipeline(elements, null);
HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);
// XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker);
p.parse(new FileInputStream(HTML), Charset.forName("UTF-8"));
PdfPTable table = new PdfPTable(1);
PdfPCell cell = new PdfPCell();
cell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
for (Element e : elements) {
cell.addElement(e);
}
table.addCell(cell);
document.add(table);
// step 5
document.close();
}
I use iText for generating PDF, from a XML file, with content in HTML. Everything is working, except one little thing.
When I have a bloc of text containing a part in BOLD, the BOLD doesn't appear in the resulting PDF file. If I have a complete phrase in BOLD, it's working fine.
Examples :
<DIV><FONT face='Arial' size='10'><B>The BOLD for this phrase works</B></FONT></DIV>
<DIV><FONT face='Arial' size='10'>The BOLD for <B>this part of the phrase </B> doesn't work</FONT></DIV>
With 'Italic' or 'Underline', I can do the same test but I don't have the problem. It's working...
A little precision : if I use a tag <B> combined with a tag <U> or <I>, for a part of bloc of text, it's working too.
Example :
<DIV><FONT face='Arial' size='10'>The combination of <B><I>BOLD and something else (U or I)</I></B> works fine.</FONT></DIV>
For the context : WebApp with struts, the PDF is not saved as a file but sent to the navigator as a response. As suggested by an answer, I update my version of iText from 1.4.8 to 5.5.7.
For the HTML code saved in a xml file, you can see examples above.
For the Java code (I picked up the code from severals long methods. I hope I forgot nothing...).
ByteArrayOutputStream baoutLettre = new ByteArrayOutputStream();
Document document = new Document();
PdfWriter myWriter = PdfWriter.getInstance(document, baoutLettre);
handleHeaderFooter(request, response, document, Constantes.Type_LETTRE);
document.open();
String lettreContent = FileHelper.readFile("myLetter.xml");
XmlParser.parse(document, new ByteArrayInputStream(lettreContent.getBytes("UTF-8")), getTagMap());
document.close();
ByteArrayOutputStream outTmp = new ByteArrayOutputStream(64000);
PdfCopyMerge pdfCM = new PdfCopyMerge(outTmp);
pdfCM.addDocument(baoutLettre.toByteArray());
pdfCM.close();
ByteArrayOutputStream outPDF = addPageNumber(outTmp.toByteArray(), soc, dicoEdition, request);
outPDF.writeTo(request.getOutputStream());
And for the class PdfCopyMerge :
public class PdfCopyMerge {
private ByteArrayOutputStream outStream = new ByteArrayOutputStream();
private Document document = null;
private PdfCopy writer = null;
public PdfCopyMerge(ByteArrayOutputStream stream) {
super();
outStream = stream;
}
public int addDocument(byte[] pdfByteArray) {
int numberOfPages = 0;
try {
PdfReader reader = new PdfReader(pdfByteArray);
numberOfPages = reader.getNumberOfPages();
if (this.document == null) {
this.document = new Document(reader.getPageSizeWithRotation(1));
this.writer = new PdfCopy(this.document, this.getOutputStream());
this.document.open();
}
PdfImportedPage page;
for (int i = 0; i < numberOfPages;) {
++i;
page = this.writer.getImportedPage(reader, i);
this.writer.addPage(page);
}
PRAcroForm form = reader.getAcroForm();
if (form != null) {
this.writer.copyAcroForm(reader);
}
} catch (Exception e) {
logger.error(e.getMessage(),e);
}
return numberOfPages;
}
Does anybody face the same problem ? I look for any helping ideas ...
Thanks.
Try the lastest version 5.5.7. Everything works fine.

I have HTML file with an external CSS. I want to create PDF from the HTML file, but the endcoing doesn't work. HTML file works fine, but after transfering to PDF, some characters in PDF are missing. (čřě...) It happens even if I set the Charset in PDFWriter constructor.
How do I solve this, please?
public void createPDF() {
try {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(username + ID + ".pdf"));
document.open();
String hovinko = username + ID + ".html";
XMLWorkerHelper.getInstance().parseXHtml(writer, document, new FileInputStream(hovinko), Charset.forName("UTF-8"));
document.close();
System.out.println("PDF Created!");
} catch (Exception ex) {
ex.printStackTrace();
}
}
Did you try to convert your special characters before writing them to your PDF?
yourHTMLString.replaceAll(oldChar, newChar);
ć = ć
ř = ř
ě = ě
If you need more special characters, visit this link.
EDIT: Then try this out, it worked for me:
BaseFont basefont = BaseFont.createFont("C:/Windows/Fonts/ARIAL.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font = new Font(basefont, 12);
document.add(new Paragraph("čřě", font));
Try it with below logic. It worked for me:
InputStream is = new ByteArrayInputStream(hovinko.getBytes(Charset.forName("UTF-8")));
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is, Charset.forName("UTF-8"));
I used xmlworker version 5.5.12 and itextpdf version 5.5.12.
I was strugling with sam problem (Polish special signs).
For me solution was to write a good font-family in html code.
