I am trying to verify digitally signed PDF document in Java. I'm using Apache PDFBox 2.0.6 to get the signature and the original PDF that was signed, then I'm using Bouncy Castle to verify detached signature(calculate the hash of the original file, verify the signature using signer's public key and compare the results). I read this article and tried to get the signature bytes and the original PDF bytes using this code: PDDocument doc = PDDocument.load(signedPDF); byte[] origPDF = doc.getSignatureDictionaries().get(0).getSignedContent(signedPDF); byte[] signature = doc.getSignatureDictionaries(

i'm trying to set an external ttf , to be able to render an image out of a pdf containing arabic caracters , the font i need to set is "Arial" , having done that the console keeps on informing that it's using the defaultFont instead of arial. org.apache.pdfbox.pdmodel.font.PDSimpleFont drawString ATTENTION: Changing font on <3> from <Arial> to the default font here's my code : import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import java.util.Iterator; import java.util.List; import java.util.Map; import javax.imageio.ImageIO; import org.apache.pdfbox.pdmodel

I try to export some data from my Java application to a pdf file. I decided to use the pdfBox library,but I realized that I could not do the Greek characters displayed properly into the pdf file. Is there a way to set the encoding? to utf8, or iso-8859-7? I try something like PdFontEncoding or Encoding but I did not get anything. Thank you for your time. gutch There are two things you would need to do: set the encoding, and provide a font with Greek characters The inbuilt fonts that most PDF readers have (ie Adobe Reader, OS X Preview, etc) only have the latin1 encoding, which doesn't include

I am using this code: https://www.tutorialspoint.com/pdfbox/pdfbox_inserting_image.htm To help me add an image to an existing PDF. The problem is that the file it creates is a blank page with only the image on it. Here is my code: public void signPDF(PdfDTO pdfDTO) throws IOException{ //Loading an existing document File file = new File(getAbsolutePdfPath(pdfDTO)); PDDocument doc = PDDocument.load(file); //Retrieving the page PDPage page = doc.getPage(0); //a test to ensure the doc is loading correctly PDDocument testDoc = new PDDocument(); testDoc.addPage(page); testDoc.save("C:" + File

I am trying to write content into a PDF file. I have written the code public ByteArrayOutputStream createPDF(String text) throws IOException, COSVisitorException { PDDocument document; PDPage page; PDFont font1; PDPageContentStream contentStream; ByteArrayOutputStream output = new ByteArrayOutputStream(); document = new PDDocument(); try { page = new PDPage(); document.addPage(page); contentStream = new PDPageContentStream(document, page); contentStream.beginText(); contentStream.moveTextPositionByAmount( 100, 700 ); contentStream.drawString("Hello World Hello World Hello World Hello World

I am new to PDFBOX. I am reading a PDF file which is in Hindi. I am having trouble reading some unicode characters out of a PDF using PDFBox. I want to copy the string into java objects so that I can work on that. There are couple of things I tried for reading the files. 1. I tried to use PDFTextStripper to read text from document but it prints garbage value and warning about missing unicode mappings. PDDocument document = PDDocument.load(pathToFile); PDFTextStripper s = new PDFTextStripper(); System.out.println(s.getText(document));//prints garbage values System.out.println(document

I am using Apache PDFBox and Java to parse the PDFs and get all the information from it. Extracting text is working fine for English only. For other languages I get only some special-characters. For example extracting the Arabic character ش will give the String :"? on printing. It is working fine when I change the "Region and language" of my computer from English to Arabic. So I think extracting the Unicode of the characters will solve this problem. Please help me to get the Unicode of the characters from PDF or suggest me some solutions to solve this problem.
