Now I can use the PDFBox to extract the outlines from PDF, but some PDF can get the outlines, others can't.
Every PDF has outlines and when I open a pdf use pdf read tool, I can click an outline to a certain page.
Here is my code:
public static void main(String[] args) {
try {
PDDocument document = PDDocument.load(new File(filePath));
PDDocumentOutline outline = document.getDocumentCatalog().getDocumentOutline();
getOutlines(document, outline, "");
document.close();
} catch (InvalidPasswordException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void getOutlines(PDDocument document, PDOutlineNode bookmark, String indentation) throws IOException{
PDOutlineItem current = bookmark.getFirstChild();
while (current != null) {
PDPage currentPage = current.findDestinationPage(document);
Integer pageNumber = document.getDocumentCatalog().getPages().indexOf(currentPage) + 1;
System.out.println(current.getTitle() + "-------->" + pageNumber);
getOutlines(document, current, indentation);
current = current.getNextSibling();
}
}

I am trying very simple steps to add colorspace to resources using PDFBOX version 2.0.7, but it is not working.
I have PDF "pdf1.pdf", I am reading the colorspaces from this file and adding them to HashMap, then I am creating new resources and trying to add the colorspaces to the newly created resources. But it is not working
So the first Step, I read the colorSpaces from the sourcePdf file and add them to HashMap:
seperationColors = new HashMap<COSName, PDColorSpace>();
PDDocument sourcePdfFile = null;
try {
sourcePdfFile = PDDocument.load(new FileInputStream(new File(pdfPath)));
PDPage page = sourcePdfFile.getPages().get(0);
page.getContents();
for (COSName name : page.getResources().getColorSpaceNames()) {
PDColor color = page.getResources().getColorSpace(name).getInitialColor();
if (color.getColorSpace() instanceof PDSeparation) {
seperationColors.put(name, page.getResources().getColorSpace(name));
}
}
} catch (FileNotFoundException e) {
// e.printStackTrace();
} catch (IOException e) {
// e.printStackTrace();
} finally {
if (sourcePdfFile != null)
try {
sourcePdfFile.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
sourcePdfFile = null;
}
}
}
Then, at later stages in the code, I want to create new PDF document, and add the colorSpaces from the source Pdf to the new one.
PDResources newResources = new PDResources();
PDColorSpace colorSpace = originalDocumentColorSpaces.values().iterator().next();
newResources.add(colorSpace);
newResources will have the error: COSDictionary{COSStream has been closed and cannot be read. Perhaps its enclosing PDDocument has been closed?}
after the add operation (line 3)
colorSpace is of type PDSeperation.
Any clue?
Please help me out.
I want to add all the steps screenshot in one document(word) file using selenium webdriver with java for that particular test case and that file should get stored with a that particular test case name.

for (int counter = 1; counter <= 5; counter++) {
captureScreenShot(docx, run, out);
TimeUnit.SECONDS.sleep(1);
}
docx.write(out);
out.flush();
out.close();
docx.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void captureScreenShot(XWPFDocument docx, XWPFRun run, FileOutputStream out) throws Exception {
String screenshot_name = System.currentTimeMillis() + ".png";
BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
File file = new File(System.getProperty("user.dir")+"\\Result\\Screenshot" + screenshot_name);
ImageIO.write(image, "png", file);
InputStream pic = new FileInputStream(System.getProperty("user.dir")+"\\Result\\Screenshot" + screenshot_name);
run.addBreak();
run.addPicture(pic, XWPFDocument.PICTURE_TYPE_PNG, screenshot_name, Units.toEMU(350), Units.toEMU(350));
pic.close();

Creating pdf file by reading a text file
using apache pdfbox 2.0.6. Text which is being read is not getting displayed and is getting cut.
Below is the sample program which I am using:-
public static void main(String[] args) {
// TODO Auto-generated method stub
PDDocument doc = null;
TextToPDF text2pdf = new TextToPDF();
try {
doc = text2pdf.createPDFFromText(new FileReader("C:/sampleTextRead2.txt"));
ByteArrayOutputStream out = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(out);
PDFTextStripper stripper = new PDFTextStripper();
stripper.writeText(doc, writer);
writer.close();
doc.save("C:/SamplePDF.pdf");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

I am using pdfbox to get the names of all fonts that are used in a pdf.
So far it was working well. However, I recently came across a pdf that has 'Webdings' font. PDFBox was not able to identify it.Could anyone help please.
This is the code I have used:
public static Set<String> extractFonts(String pdfPath) throws IOException
{
PDDocument doc = PDDocument.load(new File(pdfPath));
PDPageTree pages = doc.getDocumentCatalog().getPages();
Set<String> fontSet = new HashSet<String>();
try{
for(PDPage page:pages){
PDResources res = page.getResources();
for (COSName fontName : res.getFontNames())
{
PDFont font = res.getFont(fontName);
if(font != null){
String fontUsedName = font.getName();
if(fontUsedName.contains("+")) {
fontUsedName = fontUsedName.substring(fontUsedName.indexOf("+")+1, fontUsedName.length());
}
fontSet.add(fontUsedName);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(fontSet);
return fontSet;
}
I was able to know that the font 'Webdings' is present from the File-> Properties->Fonts option in Adobe Reader
