I'm using PDFBox 2. Trying to write a PNG image file to new PDF file.
I saw there was already an answer that mention it was fixed on PDFBox2:
How to add .png images to pdf using Apache PDFBox and
https://issues.apache.org/jira/browse/PDFBOX-1990
This is my code:
package pdfProj;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.PDPageContentStream;
import org.apache.pdfbox.pdmodel.graphics.image.LosslessFactory;
import org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject;
public class b {
public static void main(String[] args) {
PDDocument doc = null;
doc = new PDDocument();
doc.addPage(new PDPage());
try{
BufferedImage awtImage = ImageIO.read( new File( "c://temp//line_chart.png" ) );
PDImageXObject pdImageXObject = LosslessFactory.createFromImage(doc, awtImage);
PDPageContentStream contentStream = new PDPageContentStream(doc, new PDPage(), true, false);
contentStream.drawImage(pdImageXObject, 200, 300, awtImage.getWidth() / 2, awtImage.getHeight() / 2);
contentStream.close();
doc.save( "c://temp//pdf//PDF_image.pdf" );
doc.close();
} catch (Exception io){
System.out.println(" -- fail --" + io);
}
}
}
There is no exception. Just getting an empty PDF file created.
The issue is that you add a new page to the document
doc.addPage(new PDPage());
but then create a content stream for yet another new page which you don't add to the document:
PDPageContentStream contentStream = new PDPageContentStream(doc, new PDPage(), true, false);
You should create the content stream for the page you added to the document, e.g. like this:
PDDocument doc = null;
doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage(page);
try{
BufferedImage awtImage = ImageIO.read( new File( "c://temp//line_chart.png" ) );
PDImageXObject pdImageXObject = LosslessFactory.createFromImage(doc, awtImage);
PDPageContentStream contentStream = new PDPageContentStream(doc, page, true, false);
contentStream.drawImage(pdImageXObject, 200, 300, awtImage.getWidth() / 2, awtImage.getHeight() / 2);
contentStream.close();
doc.save( "c://temp//pdf//PDF_image.pdf" );
doc.close();
} catch (Exception io){
System.out.println(" -- fail --" + io);
}

I have written an android app to do inspections. It collects the data and then formats it and places it on a PDF document. I am having a problem creating a 2nd page of the PDF before I save it and email it. I have commented out "PAGE 2 OF PDF". This section of code up to the declaration of pdfName is where the problem is. I do not want to use anything like iText or Apose. Can anyone help???

I am generating PDF using PDFBox, where I need to add a checkbox, which needs to be preset to checked and readonly. But some how it does not work.
Please find below code, which adds the checkbox on PDF:
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.cos.COSArray;
import org.apache.pdfbox.cos.COSDictionary;
import org.apache.pdfbox.cos.COSFloat;
import org.apache.pdfbox.cos.COSName;
import org.apache.pdfbox.cos.COSString;
import org.apache.pdfbox.exceptions.COSVisitorException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.interactive.form.PDAcroForm;
import org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox;
import org.apache.pdfbox.pdmodel.interactive.form.PDField;
public class MyTest {
public static void main(String arg[]) throws IOException, COSVisitorException
{
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDPage.PAGE_SIZE_LETTER);
document.addPage(page);
COSDictionary acroFormDict = new COSDictionary();
acroFormDict.setItem(COSName.getPDFName("Fields"), new COSArray()); // Added this line for Tilman's comment
PDAcroForm acroForm = new PDAcroForm(document, acroFormDict);
document.getDocumentCatalog().setAcroForm(acroForm);
float x = 10f;
float y = page.getMediaBox().getHeight();
float yOffset = 15f;
float yCurrent = y - yOffset;
COSDictionary cosDict = new COSDictionary();
COSArray rect = new COSArray();
rect.add(new COSFloat(x));
rect.add(new COSFloat(yCurrent));
rect.add(new COSFloat(x+20));
rect.add(new COSFloat(yCurrent-20));
cosDict.setItem(COSName.RECT, rect);
cosDict.setItem(COSName.FT, COSName.getPDFName("Btn")); // Field Type
cosDict.setItem(COSName.TYPE, COSName.ANNOT);
cosDict.setItem(COSName.SUBTYPE, COSName.getPDFName("Widget"));
cosDict.setItem(COSName.T, new COSString("testChk"));
cosDict.setItem(COSName.DA, new COSString("/Helv 7 Tf 0 g"));
PDCheckbox checkbox = new PDCheckbox(acroForm, cosDict);
// checkbox.setReadonly(true);
// checkbox.setFieldFlags(PDField.FLAG_READ_ONLY);
checkbox.setValue("Yes");
// checkbox.check();
page.getAnnotations().add(checkbox.getWidget());
acroForm.getFields().add(checkbox); // Added this line for Tilman's comment
yCurrent = yCurrent - 20 - yOffset;
File file = new File("C:\\pdf\\CheckBox\\CheckBoxSample1.pdf");
System.out.println("Sample file saved at : " + file.getAbsolutePath());
document.save(file);
document.close();
}
}
Now if you uncomment the line:
checkbox.setReadonly(true);
Or
checkbox.setFieldFlags(PDField.FLAG_READ_ONLY);
The checkbox will no more displayed (or may be there but value is unchecked).
I am using PDFBox 1.8.10
Behavior is similar in Adobe Reader 11 and Foxit.
Also if I generate the PDF without setting the box readonly, in Adobe, I see the checkbox displayed with value set, but when I bring focus on it using tab, it gets disappear. And again on focus out (I click somewhere else other than checkbox), it appears again.
It seems like I am missing a very small thing, but could not find out.
Any help?
Thanks in advance.
You need to give field appearance using PDAppearanceCharacteristicsDictionary class. That will fix above issue.

I am using iText and some SVG rendering library.
I want to render a SVG image to PDF. I am using following code to do that. Now the problem is I am giving an area chart SVG to it, it is not rendering line properly. Attaching screenshots.
Following classes has been used:
import org.apache.batik.bridge.BridgeContext;
import org.apache.batik.bridge.DocumentLoader;
import org.apache.batik.bridge.GVTBuilder;
import org.apache.batik.bridge.UserAgent;
import org.apache.batik.bridge.UserAgentAdapter;
import org.apache.batik.dom.svg.SAXSVGDocumentFactory;
import org.apache.batik.gvt.GraphicsNode;
import org.apache.batik.util.XMLResourceDescriptor;
import org.w3c.dom.svg.SVGDocument;
and here the cop snippet:
String parser = XMLResourceDescriptor.getXMLParserClassName();
factory = new SAXSVGDocumentFactory(parser);
UserAgent userAgent = new UserAgentAdapter();
DocumentLoader loader = new DocumentLoader(userAgent);
ctx = new BridgeContext(userAgent, loader);
ctx.setDynamicState(BridgeContext.DYNAMIC);
builder = new GVTBuilder();
PdfContentByte cb = writer.getDirectContent();
PdfTemplate chartImageTemplate = cb.createTemplate(1000, 1000);
SVGDocument svgDoc=null;
try {
InputStream in = new ByteArrayInputStream(chartImage.getBytes());
svgDoc = factory.createSVGDocument("", in);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try{
GraphicsNode mapGraphics = builder.build(ctx, svgDoc);
DefaultFontMapper mapper = new DefaultFontMapper();
PdfGraphics2D g2 = (PdfGraphics2D)cb.createGraphics(1000, 500, mapper);
Graphics2D g2d = g2;
mapGraphics.paint(g2d);
g2d.dispose();
cb.addTemplate(chartImageTemplate, 0, 0);
return mapGraphics.getGeometryBounds().getHeight();
}catch(Exception e){
}

I want to add a hyperlink in PDF created using PDFBOX, such that i click on some text example 'Click here' will redirect to URL. I tried using PDAnnotationLink and PDActionURI, but how to add it in contentstream?
PDBorderStyleDictionary borderULine = new PDBorderStyleDictionary();
borderULine.setStyle(PDBorderStyleDictionary.STYLE_UNDERLINE);
PDAnnotationLink txtLink = new PDAnnotationLink();
txtLink.setBorderStyle(borderULine);
txtLink.setColour(colourBlue);
// add an action
PDActionURI action = new PDActionURI();
action.setURI("www.google.com");
txtLink.setAction(action);
contentStream.beginText();
contentStream.moveTextPositionByAmount(400, y-30);
contentStream.drawString(txtLink);----error
contentStream.endText();
To add to contentStream use the following code
PDRectangle position = new PDRectangle();
position.setLowerLeftX(10);
position.setLowerLeftY(20);
position.setUpperRightX(100);
position.setUpperRightY(10);
txtLink.setRectangle(position);
page.getAnnotations().add(txtLink);
There is a library called PDFBox-Layout which makes it easier to add hyperlinks:
Document document = new Document();
Paragraph paragraph = new Paragraph();
paragraph.addMarkup(
"This is a link to {link[https://github.com/ralfstuckert/pdfbox-layout]}PDFBox-Layout{link}",
18f, BaseFont.Helvetica);
document.add(paragraph);
final OutputStream outputStream = new FileOutputStream("link.pdf");
document.save(outputStream);
This is a fully working example, tested with PDFBox 2.0.19:
