I have a webpage with a export option to PDF. I have to display the contents of the page in the PDF. Currently I use iText PDF Library to generate PDFs. The problem is creating PDF with iText is quite a challenge. Moreover we get frequent layout/UI changes for the webpage, so we have make the same changes to PDF.
Is there any way i can convert my JSP output to PDF. Like for example "if we set the content type to contentType="application/vnd.ms-excel", a JSP table can be rendered as Excel document.
Have you checked Jasper Reports ? It has the concept of XML templates. Also same template can be used to generate Word / XLS / PDF/ CSV / XML output.
You don't need to change the iText code generation if you use it in combination with Flying Saucer (a.k.a. XhtmlRenderer). It's then basically as simple as:
String inputPath = new File("/file.xhtml").toURI().toURL().toString();
OutputStream outputStream = new FileOutputStream("/file.pdf");
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(inputPath);
renderer.layout();
renderer.createPDF(outputStream);
outputStream.close();
You can find a blog with more code samples here.
You should check wkhtmltopdf.

I have a PDF having first page as different page ( as we have in MS word functionality under "Design" tab ). and the same PDF is passed to PDFBOX using below code :
File originalPdfFile = new File("D:\\AsposeOutput_temp.pdf");
PDDocument originalDocument = PDDocument.load(originalPdfFile);
originalDocument.save("D:\\pdfBoxGen.pdf");
But when i am opening the PDF that is generated by PDFBOX, is modified. I have attached the input PDF (named AsposeOutput_temp.pdf) and output PDF (named : pdfBoxGen.pdf). I want the PDF to same as i am passing as input.
File links : https://gofile.io/?c=lLPpQz
Any help would be greatly appreciated!!
I got the solution for the above problem. There was no issue with PDFBOX library. it was with the Aspose word.The input file that was passed to PDFBOX library , was having section break internally and the same was making the improper alignment of footer.
Is it possible to set a formatted HTML-Text (Color, Alignment, ...) from a HTMLEditor to an "editable" PDF using iText.
I didn't find anything on the internet.
Thanks.
The easiest way of doing this is (as Amedee suggested) using pdfHTML.
It's an iText7 add-on that converts HTML5 (+CSS3) into pdf syntax.
The code is pretty straightforward:
HtmlConverter.convertToPdf(
"<b>This text should be written in bold.</b>", // html to be converted
new PdfWriter(
new File("C://users/user2002/output.pdf") // destination file
)
);

I found a Solution in this post using The Flying Saucer: this
I have been trying to convert html content to docx using their library and I do get a docx file created after running my app but it has blank content whereas the html does have some content in it. Please check the code below and I have included all necessary libraries from AndroidDocxtoHTML example on git.
Code:
// HTML Code
String html = "<html><head><title>Import me</title></head><body><p>Hello World!</p></body></html>";
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
AlternativeFormatInputPart afiPart = new AlternativeFormatInputPart(new PartName("/hw.html"));
afiPart.setBinaryData(html.getBytes());
afiPart.setContentType(new ContentType("text/html"));
Relationship altChunkRel = wordMLPackage.getMainDocumentPart().addTargetPart(afiPart);
// .. the bit in document body
CTAltChunk ac = Context.getWmlObjectFactory().createCTAltChunk();
ac.setId(altChunkRel.getId() );
wordMLPackage.getMainDocumentPart().addObject(ac);
// .. content type
wordMLPackage.getContentTypeManager().addDefaultContentType("html", "text/html");
I do not understand what's missing in the code that I get blank document.
I found this code for java which i modified for android.
Some people suggested using nightly build jar for xhtml conversions. Do I need to use that?
AlternativeFormatInputPart doesn't actually convert your HTML to normal docx content.
It is up to the application displaying the docx to do that (and most can't).
Instead, consider using docx4j-ImportXHTML to do the conversion.
This is not a duplicate question. I had searched and tried many options before posting this question.
We have a web page, in which user should be able to input data in text boxes, text areas, images and also Rich Text editors. This data has to be filled in an existing report, like filling the blanks.
I was able to achieve the functionality using Apache FOP when the user input is simple text. But Apache FOP doesn't work if the user input is Rich Text(html format). FOP will not render html, and it just pushes the html code(ex: <strong> XYZ /strong>) into the pdf.
I tried using iText, but the setback here is that even though iText supports rendering of html to pdf, it is not able to place the images, that are included in <img> tags, in the pdf file.
I can try to create a pdf using iText api block by block, but the problem is rich text data entered by the user can not be embedded between the code since building pdf block by block and html to pdf can not be done together in iText. Or at least that is what I think from my experience.
Is there any other way to create a pdf file from java with images, rich text rendering as it is, headers and footers?
iText provides the capability to convert HTML Data to Pdf. Below is the snippet to do it :
Lets assume the html data is available as Input Stream (If its a String then we can convert it to InputStream using Apache Commons - IOUtils)
InputStream htmlData; // Html Data that needs to converted to Pdf
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Document document = new Document();
PdfWriter pdfWriter = PdfWriter.getInstance(document, outputStream);
document.open();
// convert the HTML with the built-in convenience method
XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, document, htmlData);
document.close();
// outputStream now has the required pdf data
I am working as Social Media Developer for Aspose and to add rich text to a form field in PDF file, you can try our Aspose.Pdf for Java API. Check the following sample code:
// Open a PDF document
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("c:\\data\\input.pdf");
//Find Rich TextBox field using Field Name
RichTextBoxField textBoxField1 = (RichTextBoxField)pdfDocument.getForm().get("textbox1");
//Set the field value
textBoxField1.setValue("<strong> XYZ </strong>");
// Save the modified PDF
pdfDocument.save("c:\\data\\output2.pdf");
I am not trying to market or promote this product. This api actually solved our problem so thought of mentioning it as it might help fellow developers. please let me know if this is against your policy.
I finally realized that the solution for my requirement can not be achieved with either FOP, iText, Aspose, Flying Saucer, JODConverter.
I found a paid api Sferyx. This api allows to render a very complex html to pdf almost preserving the original style. It also renders the images included in the html. We are still exploring this api and will post what other features this api provides.
Does anyone know if it is possible to convert a HTML page (url) to a PDF using iText?
If the answer is 'no' than that is OK as well since I will stop wasting my time trying to work it out and just spend some money on one of a number of components which I know can :)
I think this is exactly what you were looking for

Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.
I have ended up using ABCPdf from webSupergoo.
It works really well and for about $350 it has saved me hours and hours based on your comments above.

The code is pretty straightforward:

The answer to your question is actually two-fold. First of all you need to specify what you intend to do with the rendered HTML: save it to a new PDF file, or use it within another rendering context (i.e. add it to some other document you are generating).
The former is relatively easily accomplished using the Flying Saucer framework, which can be found here: https://github.com/flyingsaucerproject/flyingsaucer
The latter is actually a much more comprehensive problem that needs to be categorized further.
Using iText you won't be able to (trivially, at least) combine iText elements (i.e. Paragraph, Phrase, Chunk and so on) with the generated HTML. You can hack your way out of this by using the ContentByte's addTemplate method and generating the HTML to this template.
If you on the other hand want to stamp the generated HTML with something like watermarks, dates or the like, you can do this using iText.
So bottom line: You can't trivially integrate the rendered HTML in other pdf generating contexts, but you can render HTML directly to a blank PDF document.
Use itext libray:
Here is the sample code. It is working perfectly fine:
String htmlFilePath = filePath + ".html";
String pdfFilePath = filePath + ".pdf";
// create an html file on given file path
Writer unicodeFileWriter = new OutputStreamWriter(new FileOutputStream(htmlFilePath), "UTF-8");
unicodeFileWriter.write(document.toString());
unicodeFileWriter.close();
ConverterProperties properties = new ConverterProperties();
properties.setCharset("UTF-8");
if (url.contains(".kr") || url.contains(".tw") || url.contains(".cn") || url.contains(".jp")) {
properties.setFontProvider(new DefaultFontProvider(false, false, true));
}
// convert the html file to pdf file.
HtmlConverter.convertToPdf(new File(htmlFilePath), new File(pdfFilePath), properties);

When I needed HTML to PDF conversion earlier this year, I tried the trial of Winnovative HTML to PDF converter (I think ExpertPDF is the same product, too). It worked great so we bought a license at that company. I don't go into it too in depth after that.
