pdfbox

I'm using PDFBox and iText to create a simple (just paragraphs) pdf document from various languages. Something like : pdfBox : private static void createPdfBoxDocument(File from, File to) { PDDocument document = null; try { document = new TextToPDF().createPDFFromText(new FileReader(from)); document.save(new FileOutputStream(to)); } finally { if (document != null) document.close(); } } private void createPdfBoxDoc() throws IOException, FileNotFoundException, COSVisitorException { PDDocument document = new PDDocument(); PDPage page = new PDPage(); document.addPage(page); PDPageContentStream

On the added page, I need to add some text and an image. I am wanting to give PDFBox a try. Other solutions such as iTextPDF aren't suitable for our company because of the licencing terms/price. I have a library project with the main code base, and also full and lite projects that reference the library project. I have downloaded the jar from http://pdfbox.apache.org/download.html and copied it into the library

I've been able to get the image to appear on each page, but it loses the background transparency because it appears as though PDJpeg converts it to a JPG. Perhaps there's a way to do it using PDXObjectImage. Here is what I have written thus far: public static void watermarkPDF(PDDocument pdf) throws IOException { // Load watermark BufferedImage buffered = ImageIO.read(new File("C:\\PDF_Test\\watermark.png")); PDJpeg watermark = new PDJpeg(pdf, buffered); // Loop through pages

Are there tools to determine whether a PDF has landscape orientation or portrait? I have currently looked upon pdfbox and Itext for this but seem that I could not find it. Please tell if they support this. Extracting the PDF pages information using Origami is providing a information the pdf pages have rotation of some degree. Here is what Origami reports: {:Parent=>#<PDF::Reader::Reference:0x872349c @id=8, @gen=0>, :Type=>:Page, :Contents=>#<PDF::Reader::Reference:0x8722f24 @id=4, @gen=0>, :Resources=># <PDF::Reader::Reference:0x870dbd8 @id=2, @gen=0>, :MediaBox=>[0, 0, 612, 792], :Rotate=>270

I am trying to get sizes (width and depth) of images embedded in a PDF file. The images in the PDF are all high resolution vector images. I tried using PDFBox. PDFBox libraries extract images perfectly for normal graphics. But, when it gets vector images, it extracts different layers as different images. I have also read about iText. But iText can convert the whole page as rasterized image. Whereas, my PDF page is actually consisting multiple images and I need to extract/get size of all of them differently. I am attaching my PDFBox image extraction code here. Please let me know, how can I get

I have a PDF from which I extracted a page using PDFBox: (...) File input = new File("C:\\temp\\sample.pdf"); document = PDDocument.load(input); List allPages = document.getDocumentCatalog().getAllPages(); PDPage page = (PDPage) allPages.get(2); PDStream contents = page.getContents(); if (contents != null) { System.out.println(contents.getInputStreamAsString()); (...) This gives the following result, which looks like something you'd expect, based on the PDF spec . q /GS0 gs /Fm0 Do Q /Span <</Lang (en-US)/MCID 88 >>BDC BT /CS0 cs 0 0 0 scn /GS1 gs /T1_0 1 Tf 8.5 0 0 8.5 70.8661 576 Tm (This

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. 回答1: 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)

Same question was answered here: a quick way to do this, is to remove the fields from the acrofrom. For this you just need to get the document catalog, then the acroform and then remove all fields from this acroform. The graphical representation is linked with the annotation and stay in the document. So I wrote this code: import java.io.File; import java.util.ArrayList; import java.util.List; import org.apache.pdfbox.pdmodel.PDDocument; import
