I am trying to convert HTML to PDF as encoded string. I am using openhtmltopdf library. I don't want to create a new file in users environment, so I am using ByteArrayOutputStream.
Following is my code:
Document document = Jsoup.parse(html, "UTF-8");
document.outputSettings().syntax(Document.OutputSettings.Syntax.xml);
document.outputSettings().prettyPrint(false);
// File outputpdf = new File("output.pdf");
try (ByteArrayOutputStream os = new ByteArrayOutputStream()) {
PdfRendererBuilder pdfRendererBuilder = new PdfRendererBuilder();
pdfRendererBuilder.toStream(os);
pdfRendererBuilder.withW3cDocument(new W3CDom().fromJsoup(document), "/");
pdfRendererBuilder.run();
// os.writeTo(new FileOutputStream(outputpdf));
byte[] encoded = java.util.Base64.getEncoder().encode(os.toString().getBytes());
String encodedString = new String(encoded);
I used an online base64 string to PDF decoder and generated PDF while testing. My PDF is coming as empty. When I replaced the ByteArrayOutputStream with FileOutputStream(<fileName>). It is creating a proper PDF file and also when I decode the string it is coming correct.
What am I missing in ByteArrayOutputStream?

I am using itextpdf.html2pdf to convert HTML to pdf format, but conversion converting with different language as well as alignment not correct after conversion.
Html file contains
Pdf file contains
I am using the below code to convert from HTML to pdf:
RestTemplate rTemplate = new RestTemplate();
String d = rTemplate.getForObject(url, String.class);
d = d.replaceAll("</tr>", "<td/></tr>");
org.jsoup.nodes.Document document = Jsoup.parse(d, "utf-8");
document.select("img" ).remove();
ByteArrayOutputStream outputArray = new ByteArrayOutputStream();
HtmlConverter.convertToPdf(document.html(), outputArray);
return outputArray.toByteArray();
I want to convert to pdf with the content as present in the HTML file. Also, alignment should same as an HTML file.
I'm currently converting docx to pdf, then encrypting the pdf. Here is my code:
//Convert
XWPFDocument document = new XWPFDocument(inStream);
PdfOptions options = PdfOptions.create();
PdfConverter.getInstance().convert(document, outStream, options);
//Encrypt
PdfReader reader = new PdfReader("C:\\uploads\\Resume.pdf");
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream("C:\\uploads\\ResumeEncrypt.pdf"));
stamper.setEncryption("hello123".getBytes(), "hello".getBytes(),
PdfWriter.ALLOW_PRINTING, PdfWriter.ENCRYPTION_AES_128 | PdfWriter.DO_NOT_ENCRYPT_METADATA);
stamper.close();
reader.close();
By doing this I am getting 2 files.
What is happening is first I converted the Resume.docx to Resume.pdf, then encrypted the Resume.pdf to ResumeEncrypt.pdf, resulting to 2 files
This is the example -
But I want only one file, that is already converted and encrypted.
This is the example of what I want -
Is it possible to get a single file after converting and encrypting ?
Try use ByteArrayInputStream, give convert pdf.
I made something similar few days ago. Convert Base64 to Gzip and unzip to xml in stream if you want i can give you that code like tip.
So maaybe you can base on this code
//Convert Based64, unzip to xml in stream (strLista is list of Base64 bytes
ByteArrayInputStream in = new ByteArrayInputStream(strLista.getBytes());
try(InputStream reader = Base64.getMimeDecoder().wrap(in)){
try (GZIPInputStream gis = new GZIPInputStream(reader)) {
try (ByteArrayOutputStream out = new ByteArrayOutputStream()){
int readGis = 0;
while ((readGis = gis.read(buff)) > 0)
out.write(buff, 0, readGis);
I need to encode/decode pdf file into Base64 format.
So I read file from disk into String(because I will receive file in String Base64 format in future);
String pdfString = IOUtils.toString(new FileInputStream(new
File("D:\\vrpStamped.pdf")));
byte[] encoded = Base64.encodeBase64(pdfString.getBytes());
byte[] newPdfArray = Base64.decodeBase64(encoded);
FileOutputStream imageOutFile = new FileOutputStream(
"D:\\1.pdf");
imageOutFile.write(newPdfArray);
imageOutFile.close();
imageOutFile.flush();
So my D:\\1.pdf doesnt opens in AdobeReader, but if I read file straight to byte array, using IOUtils.toByteArray(..) instead ,all works fine and my D:\\1.pdf file sucessfuly opens in Adobe Reader:
byte[] encoded = Base64.encodeBase64(IOUtils.toByteArray(new FileInputStream(new File("D:\\vrpStamped.pdf"))););
It seems to me thath IOUtils.toString(..) change something inside file content. So how can I convert file to String with not content breaking?
How to encode a pdf...
byte[] bytes = IOUtils.toByteArray(new FileInputStream(new File("/home/fschaetz/test.pdf")));
byte[] encoded = Base64.encode(bytes);
String str = new String(encoded);
...now do something with this encoded String, for example, send it via a Rest service.
And now, if you receive an encoded String, you can decode and save it like this...
byte[] decoded = Base64.decode(str.getBytes());
FileOutputStream output = new FileOutputStream(new File("/home/fschaetz/result.pdf"));
output.write(decoded);
output.close();
Works perfectly fine with all files, not limited to images or pdfs.
What your example is doing is...
Read the pdf into a String (which pretty much destroys the data, since you are reading binary data into a String)
Encode this spring (which is in all likelyhood not a valid representation of the original pdf anymore)
Decode it and save it to disk
I'm getting a response XML from web service and one of the field contains a string that should be convertable to pdf file.
This is example string that I extract from xml response:

now I'm trying to convert it into proper pdf file like this:
byte[] bytes = THAT_LONG_STRING.getBytes();
BufferedOutputStream bos = null;
FileOutputStream fos = new FileOutputStream(new File("a.pdf");
bos = new BufferedOutputStream(fos);
bos.write(bytes);
bos.flush();
bos.close();
Sadly this does not work for me, output file is just file with that long string, pdf viewers cannot open it.
Any advices are welcome :)
Your string is in Base64 format. You should decode it to a byte array first, then write it to a file.
Just replace this line:
byte[] bytes = THAT_LONG_STRING.getBytes();
With this one (Apache Commons Codec required):
byte[] bytes = Base64.decodeBase64(THAT_LONG_STRING);
We are getting Base 64 encoded graphic image as webservice response and we have to convert it to PDF file. We used bellow code snippet to transfrom base 64 encoded graphic image to pdf doc.
// First decode the Base 64 encoded graphic image
BASE64Decoder decoder = new BASE64Decoder();
byte[] decodedBytes = decoder.decodeBuffer(s);
// Create the pdf file
File file = new File("output.png");
FileOutputStream fop = new FileOutputStream(file);
fop.write(decodedBytes);
fop.flush();
fop.close();
But when we open the pdf file we are getting bellow error.
Adobe Reader could not open "output.pdf" because it is either not a supported file type or because the file has been damaged.
We tried the PDF box as bellow,
BASE64Decoder decoder = new BASE64Decoder();
byte[] decodedBytes = decoder.decodeBuffer(s);
ImageToPDF imageToPdf = new ImageToPDF();
imageToPdf.createPDFFromImage("output.pdf", decodedBytes.toString());
This also didnt help us. Please suggest me a way to creat the pdf file from Base 64 encoded graphic image.
I thing you are missing a step here. Please try following
First, create the image from the Base64 data as follows (Taken from here)
String base64String =
"BORw0KGgoAAAANSUhEUgAAAUAAAAHgCAYAAADUjLREAAAgAElEQVR4AexdB4BU1dX+ZmZ7ZWGX3pHeu6goitgQDCZGjdHYu4nGqL81mmaJvdd";
BASE64Decoder decoder = new BASE64Decoder();
byte[] decodedBytes = decoder.decodeBuffer(base64String);
log.debug("Decoded upload data : " + decodedBytes.length);
String uploadFile = "/tmp/test.png";
log.debug("File save path : " + uploadFile);
BufferedImage image = ImageIO.read(new ByteArrayInputStream(decodedBytes));
if (image == null) {
log.error("Buffered Image is null");
}
File f = new File(uploadFile);
// write the image
ImageIO.write(image, "png", f);
Please note that this example uses sun.misc.BASE64Decoder, but I would advice not to use this but use some other open source decoder (e.g apache commend-codec library is good and widely used.).
Once you have the image file, use ImageToPDF to convert the same to PDF file.
