PDFBox 2.0.9 - creating TOC with multiple pages

I'm working on PDF Toc. It generates the first page but when I have more elements I did logic to create a new page for TOC. I'm using PDF Box and that PDPageContentStream.
I had to create a function to calculate how many pages I need. Then I'm creating the exact amount of pages in the list and add them to the PDF document before I start PDPageContentStream. That stream is in a loop and it's only generating the first page. Other pages come blank. I don't know what exactly is wrong. Here is the code:
PDDocument pdf = new PDDocument();
int numberOfTocPages = calculateTocPages(50, tocStyle, _height, currentYPosition, leading);
List<PDPage> tocPages = new ArrayList<PDPage>();
for (int i = 0; i < numberOfTocPages; i++) {
PDPage toc = new PDPage(new PDRectangle(_width, _height));
tocPages.add(toc);
}
float numberingXPosition = _width - (contentMarginLeft + contentMarginRight) - 100;
int j = 0;
PDDocument temp = new PDDocument();
for (int i = 0; i < numberOfTocPages; i++) {
PDPage toc = tocPages.get(i);
pdf.addPage(toc);
try {
PDPageContentStream contentStream = new PDPageContentStream(pdf, toc, PDPageContentStream.AppendMode.APPEND, true, false);
contentStream.beginText();
if (i == 0) {
contentStream.setFont(font, fontSize);
contentStream.setNonStrokingColor(tocStyle.getHeaderFontColor());
contentStream.newLineAtOffset(headerMarginLeft, currentYPosition);
contentStream.showText(StylingEnums.TABLE_OF_CONTENTS);
}
fontSize = tocStyle.getContentFontSize();
leading = 1.5f * fontSize;
contentStream.setFont(PDType1Font.HELVETICA, fontSize);
contentStream.setNonStrokingColor(tocStyle.getContentFontColor());
contentStream.newLineAtOffset(contentMarginLeft, -leading);
currentYPosition -= leading;
contentStream.setLeading(leading);
// List<TocContentData> tocItems = _tocData.getTocItems();
while (j < 50) {
if (currentYPosition >= 2 * tocStyle.getContentMarginBottom()) {
// TocContentData item = tocItems.get(i);
contentStream.showText("Item " + j);
contentStream.newLineAtOffset(numberingXPosition, 0);
int pageNumber = j;
contentStream.showText(Integer.toString(pageNumber + 1));
contentStream.newLineAtOffset(-numberingXPosition, 0);
contentStream.newLine();
currentYPosition -= leading;
j++;
} else {
System.out.println("New page!!!");
currentYPosition = initialPosition;
break;
}
}
contentStream.endText();
contentStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
FileOutputStream out;
try {
out = new FileOutputStream(fileName + ".pdf");
pdf.save(out);
out.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Page 2 sets the Y offset with this code because currentYPosition is not used when i > 0
contentStream.newLineAtOffset(contentMarginLeft, -leading);
so your first Y offset value is negative.

PDFBox: put two A4 pages on one A3

I have a pdf document with one or more pages A4 paper.
The resulting pdf document should be A3 paper where each page contains two from the first one (odd on the left, even on the right side).
I already got it to render the A4 pages into images and the odd pages are successfully placed on the first parts of a new A3 pages but I cannot get the even pages to be placed.
public class CreateLandscapePDF {
public void renderPDF(File inputFile, String output) {
PDDocument docIn = null;
PDDocument docOut = null;
float width = 0;
float height = 0;
float posX = 0;
float posY = 0;
try {
docIn = PDDocument.load(inputFile);
PDFRenderer pdfRenderer = new PDFRenderer(docIn);
docOut = new PDDocument();
int pageCounter = 0;
for(PDPage pageIn : docIn.getPages()) {
pageIn.setRotation(270);
BufferedImage bufferedImage = pdfRenderer.renderImage(pageCounter);
width = bufferedImage.getHeight();
height = bufferedImage.getWidth();
PDPage pageOut = new PDPage(PDRectangle.A3);
PDImageXObject image = LosslessFactory.createFromImage(docOut, bufferedImage);
PDPageContentStream contentStream = new PDPageContentStream(docOut, pageOut, AppendMode.APPEND, true, true);
if((pageCounter & 1) == 0) {
pageOut.setRotation(90);
docOut.addPage(pageOut);
posX = 0;
posY = 0;
} else {
posX = 0;
posY = width;
}
contentStream.drawImage(image, posX, posY);
contentStream.close();
bufferedImage.flush();
pageCounter++;
}
docOut.save(output + "\\LandscapeTest.pdf");
docOut.close();
docIn.close();
} catch(IOException io) {
io.printStackTrace();
}
}
}
I'm using Apache PDFBox 2.0.2 (pdfbox-app-2.0.2.jar)

Thank you very much for your help and the link to the other question - I think I already read it but wasn't able to use in in my code yet.
But finally the PDFClown made the job, though I think it's not very nice to use PDFBox and PDFClown in the same program.
Anyway here's my working code to combine A4 pages on A3 paper.
public class CombinePages {
public void run(String input, String output) {
try {
Document source = new File(input).getDocument();
Pages sourcePages = source.getPages();
Document target = new File().getDocument();
Page targetPage = null;
int pageCounter = 0;
double moveByX = .0;
for(Page sourcePage : source.getPages()) {
if((pageCounter & 1) == 0) {
//even page gets a blank page
targetPage = new Page(target);
target.setPageSize(PageFormat.getSize(PageFormat.SizeEnum.A3, PageFormat.OrientationEnum.Landscape));
target.getPages().add(targetPage);
moveByX = .0;
} else {
moveByX = .50;
}
//get content from source page
XObject xObject = sourcePages.get(pageCounter).toXObject(target);
PrimitiveComposer composer = new PrimitiveComposer(targetPage);
Dimension2D targetSize = targetPage.getSize();
Dimension2D sourceSize = xObject.getSize();
composer.showXObject(xObject, new Point2D.Double(targetSize.getWidth() * moveByX, targetSize.getHeight() * .0), new Dimension(sourceSize.getWidth(), sourceSize.getHeight()), XAlignmentEnum.Left, YAlignmentEnum.Top, 0);
composer.flush();
pageCounter++;
}
target.getFile().save(output + "\\CombinePages.pdf", SerializationModeEnum.Standard);
source.getFile().close();
} catch (FileNotFoundException fnf) {
log.error(fnf);
} catch (IOException io) {
log.error(io);
}
}
}

Create Multiple Sheet in jExcel API

I need to create multiple excel sheet in Java using jExcel API if one sheet is full (65536 rows). Suppose if one sheet got full then in the next sheet it should start writing automatically from where it left off in the first sheet. I am just stuck on putting the logic to create it dynamically whenever one sheet is full. Below is the code that I have done so far.
public void write() throws IOException, WriteException {
File file = new File(inputFile);
WorkbookSettings wbSettings = new WorkbookSettings();
wbSettings.setLocale(new Locale("en", "EN"));
WritableWorkbook workbook = Workbook.createWorkbook(file, wbSettings);
writingToExcel(workbook);
}
//Logic to create sheet dyanmically if one is full should be done here I guess?
private void writingToExcel(WritableWorkbook workbook) {
workbook.createSheet("Report", 0);
WritableSheet excelSheet = workbook.getSheet(0);
try {
createLabel(excelSheet);
createContent(excelSheet);
} catch (WriteException e) {
e.printStackTrace();
} finally {
try {
workbook.write();
workbook.close();
} catch (IOException e) {
e.printStackTrace();
} catch (WriteException e) {
e.printStackTrace();
}
}
}
private void createLabel(WritableSheet sheet) throws WriteException {
WritableFont times10pt = new WritableFont(WritableFont.TIMES, 10);
times = new WritableCellFormat(times10pt);
times.setWrap(true);
WritableFont times10ptBoldUnderline = new WritableFont(WritableFont.TIMES, 10, WritableFont.BOLD, false,UnderlineStyle.SINGLE);
timesBoldUnderline = new WritableCellFormat(times10ptBoldUnderline);
timesBoldUnderline.setWrap(true);
CellView cv = new CellView();
cv.setFormat(times);
cv.setFormat(timesBoldUnderline);
cv.setAutosize(true);
// Write a few headers
addCaption(sheet, 0, 0, "Header 1");
addCaption(sheet, 1, 0, "This is another header");
}
private void createContent(WritableSheet sheet) throws WriteException,
RowsExceededException {
for (int i = 1; i < 70000; i++) {
addNumber(sheet, 0, i, i + 10);
addNumber(sheet, 1, i, i * i);
}
}
private void addCaption(WritableSheet sheet, int column, int row, String s)
throws RowsExceededException, WriteException {
Label label;
label = new Label(column, row, s, timesBoldUnderline);
sheet.addCell(label);
}
private void addNumber(WritableSheet sheet, int column, int row,
Integer integer) throws WriteException, RowsExceededException {
Number number;
number = new Number(column, row, integer, times);
sheet.addCell(number);
}
I am not sure how to add that logic here in my code.
Any suggestions will be of great help?
Or in any case, can anyone provide me a simple example in which if one sheet is full, it should start writing automatically into different sheet (Second sheet)?

I made changes to the following 2 methods:-
private void writingToExcel(WritableWorkbook workbook) {
try {
// don't create a sheet now, instead, pass it in the workbook
createContent(workbook);
}
catch (WriteException e) {
e.printStackTrace();
}
finally {
try {
workbook.write();
workbook.close();
}
catch (IOException e) {
e.printStackTrace();
}
catch (WriteException e) {
e.printStackTrace();
}
}
}
// instead of taking a sheet, take a workbook because we cannot ensure if the sheet can fit all the content at this point
private void createContent(WritableWorkbook workbook) throws WriteException {
int excelSheetIndex = 0;
int rowIndex = 0;
WritableSheet excelSheet = null;
for (int i = 1; i < 70000; i++) {
// if the sheet has hit the cap, then create a new sheet, new label row and reset the row count
if (excelSheet == null || excelSheet.getRows() == 65536) {
excelSheet = workbook.createSheet("Report " + excelSheetIndex, excelSheetIndex++);
createLabel(excelSheet);
rowIndex = 0;
}
// instead of using i for row, use rowIndex
addNumber(excelSheet, 0, rowIndex, i + 10);
addNumber(excelSheet, 1, rowIndex, i * i);
// increment the sheet row
rowIndex++;
}
}

How to read bookmarks in PDF using itext at multi level?

I am using iText-Java to split PDFs at bookmark level.
Does anybody know or have any examples for splitting a PDF at bookmarks that exist at a level 2 or 3?
For ex: I have the bookmarks in the following levels:
Father
|-Son
|-Son
|-Daughter
|-|-Grand son
|-|-Grand daughter
Right now I have below code to read the bookmark which reads the base bookmark(Father). Basically SimpleBookmark.getBookmark(reader) line did all the work.
But I want to read the level 2 and level 3 bookmarks to split the content present between those inner level bookmarks.
public static void splitPDFByBookmarks(String pdf, String outputFolder){
try
{
PdfReader reader = new PdfReader(pdf);
//List of bookmarks: each bookmark is a map with values for title, page, etc
List<HashMap> bookmarks = SimpleBookmark.getBookmark(reader);
for(int i=0; i<bookmarks.size(); i++){
HashMap bm = bookmarks.get(i);
HashMap nextBM = i==bookmarks.size()-1 ? null : bookmarks.get(i+1);
//In my case I needed to split the title string
String title = ((String)bm.get("Title")).split(" ")[2];
log.debug("Titel: " + title);
String startPage = ((String)bm.get("Page")).split(" ")[0];
String startPageNextBM = nextBM==null ? "" + (reader.getNumberOfPages() + 1) : ((String)nextBM.get("Page")).split(" ")[0];
log.debug("Page: " + startPage);
log.debug("------------------");
extractBookmarkToPDF(reader, Integer.valueOf(startPage), Integer.valueOf(startPageNextBM), title + ".pdf",outputFolder);
}
}
catch (IOException e)
{
log.error(e.getMessage());
}
}
private static void extractBookmarkToPDF(PdfReader reader, int pageFrom, int pageTo, String outputName, String outputFolder){
Document document = new Document();
OutputStream os = null;
try{
os = new FileOutputStream(outputFolder + outputName);
// Create a writer for the outputstream
PdfWriter writer = PdfWriter.getInstance(document, os);
document.open();
PdfContentByte cb = writer.getDirectContent(); // Holds the PDF data
PdfImportedPage page;
while(pageFrom < pageTo) {
document.newPage();
page = writer.getImportedPage(reader, pageFrom);
cb.addTemplate(page, 0, 0);
pageFrom++;
}
os.flush();
document.close();
os.close();
}catch(Exception ex){
log.error(ex.getMessage());
}finally {
if (document.isOpen())
document.close();
try {
if (os != null)
os.close();
} catch (IOException ioe) {
log.error(ioe.getMessage());
}
}
}
Your help is much appreciated.
Thanks in advance! :)

You get an ArrayList<HashMap> when you call SimpleBookmark.getBookmark(reader); (do the cast if you need it). Try to iterate through that Arraylist and see its structure. If a bookmarks have sons (as you call it), it will contains another list with the same structure.
A recursive method could be the solution.

Reference for those who are looking at this using itext7
public void walkOutlines(PdfOutline outline, Map<String, PdfObject> names, PdfDocument pdfDocument,List<String>titles,List<Integer>pageNum) { //----------loop traversing all paths

PDFBox - merge 2 portrait pages onto a single side by side landscape page

I am trying to write a pdf conversion, that will take a pdf containing 1-up portrait pages, and create a new document, but merge every 2 pages into one 2-up landscape page
ie.
the following code will scale down the content 50%, but I cant figure out how to make the new page landscape, while injecting the other page as portrait, and injecting into the top left, and right of centre
public static void main(String[] args) throws IOException, DocumentException, COSVisitorException {
scalePages("c:/pdf/in.pdf", "c:/pdf/out" + new Date().getTime() + ".pdf", 0.50f);
}
public static void scalePages(String inFile, String outFile, float scale ) throws IOException, COSVisitorException {
PDDocument doc1 = null;
try {
doc1 = PDDocument.load( inFile );
List allPages = doc1.getDocumentCatalog().getAllPages();
for( int i=0; i<allPages.size(); i++ ) {
PDPage page1 = (PDPage)allPages.get(i );
PDRectangle mediaBox = page1.getMediaBox();
float oldX = mediaBox.getUpperRightX();
float newX = oldX * scale;
float oldY = mediaBox.getUpperRightY();
float newY = oldY * scale;
mediaBox.setUpperRightX(newX);
mediaBox.setUpperRightY(newY);
PDFStreamParser parser = new PDFStreamParser(page1.getContents());
parser.parse();
List tokens = parser.getTokens();
tokens.add(0,new COSFloat(scale));
tokens.add(1,new COSInteger(0));
tokens.add(2,new COSInteger(0));
tokens.add(3,new COSFloat(scale));
tokens.add(4,new COSInteger(0));
tokens.add(5,new COSInteger(0));
tokens.add(6,PDFOperator.getOperator("cm"));
PDStream newContents = new PDStream( doc1 );
ContentStreamWriter writer = new ContentStreamWriter( newContents.createOutputStream() );
writer.writeTokens( tokens );
newContents.addCompression();
page1.setContents(newContents);
//page1.setRotation(90);
mediaBox.setUpperRightX(oldX);
mediaBox.setUpperRightY(oldY);
}
doc1.save( outFile );
} finally {
if( doc1 != null ) {
doc1.close();
}
}
}
so the result is as follows
any pointers would be greatly appreciated

Here is an example that "stitches" two one page PDFs side-by-side and saves result in a new file using PDFBox. Enjoy!
function void generateSideBySidePDF() {
File pdf1File = new File(FILE1_PATH);
File pdf2File = new File(FILE2_PATH);
File outPdfFile = new File(OUTFILE_PATH);
PDDocument pdf1 = null;
PDDocument pdf2 = null;
PDDocument outPdf = null;
try {
pdf1 = PDDocument.load(pdf1File);
pdf2 = PDDocument.load(pdf2File);
outPdf = new PDDocument();
// Create output PDF frame
PDRectangle pdf1Frame = pdf1.getPage(0).getCropBox();
PDRectangle pdf2Frame = pdf2.getPage(0).getCropBox();
PDRectangle outPdfFrame = new PDRectangle(pdf1Frame.getWidth()+pdf2Frame.getWidth(), Math.max(pdf1Frame.getHeight(), pdf2Frame.getHeight()));
// Create output page with calculated frame and add it to the document
COSDictionary dict = new COSDictionary();
dict.setItem(COSName.TYPE, COSName.PAGE);
dict.setItem(COSName.MEDIA_BOX, outPdfFrame);
dict.setItem(COSName.CROP_BOX, outPdfFrame);
dict.setItem(COSName.ART_BOX, outPdfFrame);
PDPage outPdfPage = new PDPage(dict);
outPdf.addPage(outPdfPage);
// Source PDF pages has to be imported as form XObjects to be able to insert them at a specific point in the output page
LayerUtility layerUtility = new LayerUtility(outPdf);
PDFormXObject formPdf1 = layerUtility.importPageAsForm(pdf1, 0);
PDFormXObject formPdf2 = layerUtility.importPageAsForm(pdf2, 0);
// Add form objects to output page
AffineTransform afLeft = new AffineTransform();
layerUtility.appendFormAsLayer(outPdfPage, formPdf1, afLeft, "left");
AffineTransform afRight = AffineTransform.getTranslateInstance(pdf1Frame.getWidth(), 0.0);
layerUtility.appendFormAsLayer(outPdfPage, formPdf2, afRight, "right");
outPdf.save(outPdfFile);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (pdf1 != null) pdf1.close();
if (pdf2 != null) pdf2.close();
if (outPdf != null) outPdf.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

I ended up doing this with itext
private String createTwoUp(String originalPdfFile) throws IOException, DocumentException {
String newFilename = FilenameUtils.getBaseName(originalPdfFile) + "_2up." + FilenameUtils.getExtension(originalPdfFile);
newFilename = FilenameUtils.concat(getPdfFileFolder(), newFilename);
PdfReader reader = new PdfReader(originalPdfFile);
Document doc = new Document(new RectangleReadOnly(842f, 595f), 0, 0, 0, 0);
PdfWriter writer = PdfWriter.getInstance(doc, new FileOutputStream(newFilename));
doc.open();
int totalPages = reader.getNumberOfPages();
for (int i = 1; i <= totalPages; i = i + 2) {
doc.newPage();
PdfContentByte cb = writer.getDirectContent();
PdfImportedPage page = writer.getImportedPage(reader, i); // page #1
float documentWidth = doc.getPageSize().getWidth() / 2;
float documentHeight = doc.getPageSize().getHeight();
if (i > 1) {
documentHeight = documentHeight - 65f;
}
float pageWidth = page.getWidth();
float pageHeight = page.getHeight();
float widthScale = documentWidth / pageWidth;
float heightScale = documentHeight / pageHeight;
float scale = Math.min(widthScale, heightScale);
//float offsetX = 50f;
float offsetX = (documentWidth - (pageWidth * scale)) / 2;
float offsetY = 0f;
cb.addTemplate(page, scale, 0, 0, scale, offsetX, offsetY);
if (i+1 <= totalPages) {
PdfImportedPage page2 = writer.getImportedPage(reader, i+1); // page #2
pageWidth = page.getWidth();
pageHeight = page.getHeight();
widthScale = documentWidth / pageWidth;
heightScale = documentHeight / pageHeight;
scale = Math.min(widthScale, heightScale);
offsetX = ((documentWidth - (pageWidth * scale)) / 2) + documentWidth;
cb.addTemplate(page2, scale, 0, 0, scale, offsetX, offsetY);
}
}
doc.close();
return newFilename;
}
