I’m using PDFBox 2.0.4 to create PDF documents with acroForms. Here is my test code example:
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
document.getDocumentCatalog().setAcroForm(acroForm);
String dir = "../testPdfBox/src/main/resources/fonts/";
PDType0Font font = PDType0Font.load(document, new File(dir + "Roboto-Regular.ttf"));
PDResources resources = new PDResources();
String fontName = resources.add(font).getName();
acroForm.setDefaultResources(resources);
String defaultAppearanceString = format("/%s 12 Tf 0 g", fontName);
acroForm.setDefaultAppearance(defaultAppearanceString);
PDTextField field = new PDTextField(acroForm);
field.setPartialName("SampleField");
field.setDefaultAppearance(defaultAppearanceString);
acroForm.getFields().add(field);
PDAnnotationWidget widget = field.getWidgets().get(0);
PDRectangle rect = new PDRectangle(50, 750, 200, 50);
widget.setRectangle(rect);
widget.setPage(page);
widget.setPrinted(true);
page.getAnnotations().add(widget);
field.setValue("Sample field 123456");
acroForm.flatten();
document.save("target/SimpleForm.pdf");
document.close();
Everything works fine. But when I try to copy text from the created document and paste it to the NotePad or Word it becomes squares.
I search a lot about this problem. The most popular answer is that there is no toUnicode cmap in created PDF. So I explore my document with CanOpener for Acrobat:
Yes, there is no toUnicode cmap, but everything works properly, if not to use acroForm.flatten(). When form fields are not flattened, I can copy/paste text from the document and it looks correct. Nevertheless I need all fields to be flattened.
So, I have two questions:
Why there is a problem with copy/pasting text in flattened form, and everything is ok in non-flattened?
What can I do to avoid problem with text copy/pasting?
Is there only one solution - to create toUnicode CMap by my own, like in this example?
My test pdf files are available here.
Please replace
PDType0Font font = PDType0Font.load(document, new File(dir + "Roboto-Regular.ttf"));
with
PDType0Font font = PDType0Font.load(document, new FileInputStream(dir + "Roboto-Regular.ttf"), false);
This makes sure that the font is embedded in full and not just as a subset.
I want to create a new pdf for each iteration of the loop so i wrote the below code in java:
PdfWriter writer;
PdfDocument pdf;
Document document;
int i=0;
while(condition){
writer = new PdfWriter("test_"+Integer.toString(i)+".pdf");
pdf = new PdfDocument(writer);
document = new Document(pdf);
//content code here
document.close()
i++;
}
i get the below exception on the line of the document.close() command:
Exception in thread "main" com.itextpdf.kernel.PdfException: Pdf

i have tried a lot but i cannot find why i get an error. If i do it without a loop it works. Any help?
P.S: i use itext 7
I had the below code out of the loop and it should be into the loop...
PdfFont normalFont = PdfFontFactory.createFont(fontDirectory.getAbsolutePath()+"\\arial.ttf", "Identity-H", true);
normal.setFont(normalFont).setFontSize(14);
Style red = new Style();
PdfFont redFont = PdfFontFactory.createFont(fontDirectory.getAbsolutePath()+"\\arial.ttf", "Identity-H", true);
red.setFont(redFont).setFontSize(14).setFontColor(Color.RED);
Style big = new Style();
PdfFont bigFont = PdfFontFactory.createFont(fontDirectory.getAbsolutePath()+"\\arial.ttf", "Identity-H", true);
big.setFont(bigFont).setFontSize(18).setBold();

the dummy.txt is a simple html with aranic and latin characters

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"));

PdfPCell cell = new PdfPCell();
cell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);

cell.addElement(e);
}
table.addCell(cell);
document.add(table);
// step 5
document.close();

I am trying to create a pdf/a 1a document with iText 5.5.2
I can create a simple pdf/a with hello world but I am not able to add an image in the document without the error:
com.itextpdf.text.pdf.PdfAConformanceException: Alt entry should specify alternate description for /Figure element.
Below is my code tryout. I don't know how to add Alt entry Figure for the image. I tried with the PdfDictionary but it does not work. I am out of idea's. Does anyone have a tip for me?
final float MARGIN_OF_ONE_CM = 28.8f;
final com.itextpdf.text.Document document = new com.itextpdf.text.Document(PageSize.A4
, MARGIN_OF_ONE_CM
, MARGIN_OF_ONE_CM
, MARGIN_OF_ONE_CM
, MARGIN_OF_ONE_CM);
ByteArrayOutputStream pdfAsStream = new ByteArrayOutputStream();
PdfAWriter writer = PdfAWriter.getInstance(document,
new FileOutputStream("D:\\tmp\\pdf\\test.pdf"), PdfAConformanceLevel.PDF_A_1A);
document.addAuthor("Author");
document.addSubject("Subject");
document.addLanguage("nl-nl");
document.addCreationDate();
document.addCreator("Creator");
document.addTitle("title");
writer.setPdfVersion(PdfName.VERSION);
writer.setTagged();
writer.createXmpMetadata();
document.open();
final String FONT = "./src/main/resources/fonts/arial.ttf";
Font font = FontFactory.getFont(FONT, BaseFont.CP1252, BaseFont.EMBEDDED);
final Paragraph element = new Paragraph("Hello World", font);
document.add(element);
final InputStream logo = this.getClass().getResourceAsStream("/logos/logo.jpg");
final byte[] bytes = IOUtils.toByteArray(logo);
Image logoImage = Image.getInstance(bytes);
document.add(logoImage);
final String colorProfile = "/color/sRGB Color Space Profile.icm";
final InputStream resourceAsStream = this.getClass().getResourceAsStream(colorProfile);
ICC_Profile icc = ICC_Profile.getInstance(resourceAsStream);
writer.setOutputIntents("Custom", "", "http://www.color.org", "sRGB IEC61966-2.1", icc);
document.close();
Normally, you need to add the alternate description like this:
logoImage.setAccessibleAttribute(PdfName.ALT, new PdfString("Logo"));
This works for PDF/A2-A and PDF/A3-A, but not for PDF/A1-A. I have tested this and I see that you have discovered a bug. This bug has now been fixed. The fix will be in the next release.
I want to do the following with iText:
(1) parse an existing PDF file
(2) add some data to it, on the existing single page of the document (such as a timestamp)
(3) write out the document
I just can't seem to figure out how to do this with iText. In pseudo code I would do this:
Document document = reader.read(input);
document.add(new Paragraph("my timestamp"));
writer.write(document, output);
But for some reason iText's API is so dauntingly complicated that I can't wrap my head around it. The PdfReader actually holds the document model or something (rather than spitting out a document), and you need a PdfWriter to read pages from it... eh?
iText has more than one way of doing this. The PdfStamper class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.
// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1);
// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);
// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp"));
document.close();
This will read in a PDF from templateInputStream and write it out to outputStream. These might be file streams or memory streams or whatever suits your application.
Gutch's code is close, but it'll only work right if:
There are no annotations (links, fields, etc), no Document Structure/Marked Content, no bookmarks, no document-level script, etc, etc, etc...
The page size happens to be A.4 (decent odds, but it won't work on any ol' PDF you happen to come across)
You don't mind losing all the original document metadata (producer, creation date, possibly author/title/keywords), and maybe the document ID. You can't copy the creation date and doc ID unless you do some pretty deep hackery on iText itself).
The Approved Method is to do it the other way around. Open the existing document with a PdfStamper, and use the returned PdfContentByte from getOverContent() to write text (and whatever else you might need) directly to the page. No second document needed.
And you can use a ColumnText to handle layout and such for you... no need to get down and dirty with beginText(),setFontAndSize(),drawText(),drawText()...,endText().
This is the most complicated scenario I can imagine: I have a PDF file created with Ilustrator and modified with Acrobat to have AcroFields (AcroForm) that I'm going to fill with data with this Java code, the result of that PDF file with the data in the fields is modified adding a Document.
Actually in this case I'm dynamically generating a background that is added to a PDF that is also dynamically generated with a Document with an unknown amount of data or pages.
I'm using JBoss and this code is inside a JSP file (should work in any JSP webserver).
Note: if you are using IExplorer you must submit a HTTP form with POST method to be able to download the file. If not you are going to see the PDF code in the screen. This does not happen in Chrome or Firefox.

String str = "";

Document doc = new Document( PageSize.A4, 25, 25, 200, 70 );
ByteArrayOutputStream streamDoc = new ByteArrayOutputStream();
PdfWriter.getInstance( doc, streamDoc );
// lets start filling with info
doc.open();
doc.add(new Paragraph(str));
doc.close();
// the beauty of this is the PDF will have all the pages it needs
PdfReader frente = new PdfReader(streamDoc.toByteArray());
PdfStamper stamperDoc = new PdfStamper( frente, response.getOutputStream());
// -------- THE BACKGROUND PDF FILE -------
// in JBoss the file has to be in webinf/classes to be readed this way
PdfReader fondo = new PdfReader("listaPrecios.pdf");
ByteArrayOutputStream streamFondo = new ByteArrayOutputStream();
PdfStamper stamperFondo = new PdfStamper( fondo, streamFondo);
// the acroform
AcroFields form = stamperFondo.getAcroFields();
// the fields
form.setField("nombre","Avicultura");

stamperFondo.setFormFlattening(true);
stamperFondo.close();

PdfReader fondoEstampado = new PdfReader( streamFondo.toByteArray() );
// ---- ADDING THE BACKGROUND TO EACH DATA PAGE ---------
PdfImportedPage pagina = stamperDoc.getImportedPage(fondoEstampado,1);

PdfContentByte background;

background = stamperDoc.getUnderContent(i);
background.addTemplate(pagina, 0, 0);
}
// after this everithing will be written in response.getOutputStream()
stamperDoc.close();

There is another solution much simpler, and solves your problem. It depends the amount of text you want to add.
// read the file
PdfReader fondo = new PdfReader("listaPrecios.pdf");
PdfStamper stamper = new PdfStamper( fondo, response.getOutputStream());
PdfContentByte content = stamper.getOverContent(1);
// add text
ColumnText ct = new ColumnText( content );
// this are the coordinates where you want to add text
// if the text does not fit inside it will be cropped
ct.setSimpleColumn(50,500,500,50);
ct.setText(new Phrase(str, titulo1));
ct.go();

new FileOutputStream("E:/TextFieldForm.pdf"));
