Unable to read PDF using itextpdf

I am using itextpdf-5.5.4 jar to merge or add two pdf into one PDF.
I did not get any error or exception while running code but displayed below text in Merged PDF. I did not get below text when i open individual PDF's.

Non removable watermark on PDF file using iText in Java

We have a requirement where we need to add text watermark on magazines which has multiple rich images on each page. I tried com.itextpdf.jar version 5.0.6 to add the watermark but eventually I am able to remove it using Adobe Acrobat Pro.
I tried below option also but that too didn't work.
stamper.setFreeTextFlattening(true);
Is it possible with iText to add a watermark which can not be removed without much effort.
Below is my implementation.
public static void addWaterMark() throws IOException, DocumentException {
PdfReader reader = new PdfReader("C:/Trade-catalog/Catalog2017.pdf");
ByteArrayOutputStream outputPdf = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, outputPdf);
String bodyWatermarkText = "12345 - John Smith";
String bodyWatermarkRotation = "35";
String footerWatermarkText = "Richard Parker";
BaseFont font = BaseFont.createFont("/fonts/micross.ttf", "Cp1250", BaseFont.EMBEDDED);
PdfGState state = new PdfGState();
state.setFillOpacity(0.3f);
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
Rectangle thisPageSize = reader.getPageSize(i);
PdfPatternPainter bodyPainter = stamper.getOverContent(i).createPattern(thisPageSize.getWidth(),
thisPageSize.getHeight());
bodyPainter.setColorFill(new BaseColor(0, 0, 0));
bodyPainter.beginText();
bodyPainter.setTextRenderingMode(PdfPatternPainter.TEXT_RENDER_MODE_FILL);
bodyPainter.setFontAndSize(font, 60);
bodyPainter.showTextAlignedKerned(Element.ALIGN_CENTER, bodyWatermarkText, thisPageSize.getWidth() / 2,
thisPageSize.getHeight() / 2, Integer.valueOf(bodyWatermarkRotation));
bodyPainter.showTextAlignedKerned(Element.ALIGN_RIGHT, footerWatermarkText, thisPageSize.getWidth() * 0.97f,
thisPageSize.getHeight() * 0.015f, 0);
bodyPainter.endText();
PdfContentByte overContent = stamper.getOverContent(i);
overContent.setGState(state);
overContent.setColorFill(new PatternColor(bodyPainter));
overContent.rectangle(thisPageSize.getLeft(), thisPageSize.getBottom(), thisPageSize.getWidth(),
thisPageSize.getHeight());
overContent.fill();
overContent.setFlatness(100);
}
stamper.close();
FileOutputStream outputStream = new FileOutputStream(
"C:/Trade-catalog/output/TradeCatalog2017Watermarked_bodyPainter.pdf");
outputPdf.writeTo(outputStream);
outputPdf.close();
reader.close();
}

Merging PDFs with iText 2.1.7 is causing them to shrink

I am using iText 2.1.7 to merge some document PDFs into a single PDF. The code below seems to work just fine, however it appears in some instances the rendered PDF is scaled slightly smaller, like at 90% of the PDF if printed directly before processing.
Is there a way to keep the current size?
private void doMerge(List<InputStream> list, OutputStream outputStream) throws DocumentException, IOException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
for (InputStream in : list) {
PdfReader reader = new PdfReader(in);
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
document.newPage();
//import the page from source pdf
PdfImportedPage page = writer.getImportedPage(reader, i);
//add the page to the destination pdf
cb.addTemplate(page, 0, 0);
}
}
outputStream.flush();
document.close();
outputStream.close();
}

The API was already available with that version. I would even suggest to use PdfSmartCopy instead of PdfCopy (or PdfCopyFields if form fields are inside).
private PdfSmartCopy copier;
public void SomeMainMethod(){
Document finalPdf = new Document();
copier = new PdfSmartCopy(finalPdf, outputstream);
//Start adding pdfs
finalPdf.open();
//add n documents
addDocuments(...);
finalPdf.close();
formCopier.close();
}
public void addDocument(InputStream pdfDocument, int startPage, int endPage){
PdfReader reader= new PdfReader(pdfDocument);
int startPage = 1;
int endPage = reader.getNumberOfPages();
for (int i = startPage; i <= endPage; i++) {
copier.addPage(this.copier.getImportedPage(reader,i));
}
if(copier!=null){
//Important: Free Memory!
copier.flush();
copier.freeReader(reader);
}
if (reader!=null) {
reader.close();
reader=null;
}
pdfDocument.close();
}

Jasper Report how to create an excel xlsx file with RTL sheet?

We are using jasper version 6. We can export to EXCEL ( XLS and XLSX) .
Below code works for XLS and creates a RTL sheet:
exporter = new JRXlsExporter();
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(out));
SimpleXlsReportConfiguration xlsReportConfig = new SimpleXlsReportConfiguration();
xlsReportConfig.setSheetDirection(RunDirectionEnum.RTL);
exporter.setConfiguration(xlsReportConfig);
However when I try the same code to make a XLSX file the sheet direction will not change to RTL:
exporter = new JRXlsxExporter();
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(out));
SimpleXlsxReportConfiguration xlsxReportConfiguration = new SimpleXlsxReportConfiguration();
xlsxReportConfiguration.setSheetDirection(RunDirectionEnum.RTL);
exporter.setConfiguration(xlsxReportConfiguration);

I finally used below code ( It is costy but works) , which is mentioned at https://community.jaspersoft.com/questions/523041/right-left-arabic-reports
public class ReportUtils {
private ReportUtils(){
}
/**
* mirror each page layout
* #param print
*/
public static void mirrorLayout(JasperPrint print) {
int pageWidth = print.getPageWidth();
for (Object element : print.getPages()) {
JRPrintPage page = (JRPrintPage) element;
mirrorLayout(page.getElements(), pageWidth);
}
}
/**
* mirror a list of elements
* #param print
*/
protected static void mirrorLayout(List<?> elements, int totalWidth) {
for (Iterator<?> it = elements.iterator(); it.hasNext();) {
JRPrintElement element = (JRPrintElement) it.next();
int mirrorX = totalWidth - element.getX() - element.getWidth();
element.setX(mirrorX);
if (element instanceof JRPrintFrame) {
JRPrintFrame frame = (JRPrintFrame) element;
mirrorLayout(frame.getElements(), frame.getWidth());
}
}
}
}
Use it like:
Exporter exporter;
ByteArrayOutputStream out = new ByteArrayOutputStream();
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(out));
JasperPrint jasperPrint = JasperFillManager.fillReport(report,
params, dataSource != null ? new JRMapArrayDataSource(
dataSource) : new JREmptyDataSource());
ReportUtils.mirrorLayout(jasperPrint);
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.exportReport();
return out.toByteArray();

Seems to be a bug in the jasper report library tested with v 6.1.1, adding code below after export it will work correctly (with poi libraries included in jasper report distribution, so no bug in POI...).
//out is the file after jasper report export
XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream(out));
int ns = workbook.getNumberOfSheets();
for (int i = 0; i < ns; i++) {
XSSFSheet sheet = workbook.getSheetAt(i);
sheet.setRightToLeft(true);
}
FileOutputStream outStream = new FileOutputStream(out);
workbook.write(outStream);
outStream.close();
Current bug report tracker on jaspersoft community

I had a problem generating a report in XLSX, in the last version of JasperReports 6.1, but this code works for me:
Firstly, i configure the jasper print
JRSwapFile swapFile = new JRSwapFile(".", 1024, 1024);
JRVirtualizer virtualizer = new JRSwapFileVirtualizer(100, swapFile, true);
parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer);
JasperPrint print = JasperFillManager.fillReport(stream, parameters, dbConnection);
List<JasperPrint> prints = new ArrayList<JasperPrint>();
prints.add(print);
After that, i configure the output for the generated report, in my case the report will be managed in memory by an ByteArrayOutputStream:
ByteArrayOutputStream output = new ByteArrayOutputStream();
I create an instance of JRXlsxExporter for generate a file with the .xslx extension, and putting the printers and the output:
JRXlsxExporter exporter = new JRXlsxExporter();
exporter.setExporterInput(SimpleExporterInput.getInstance(prints));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(output));
The next step is to create the report configuration for the exporter, when i put this code my report works!, so you must use it!:
SimpleXlsxReportConfiguration xlsxReportConfiguration = new SimpleXlsxReportConfiguration();
xlsxReportConfiguration.setSheetDirection(RunDirectionEnum.RTL);
exporter.setConfiguration(xlsxReportConfiguration);
Finally, generate the report and close the outputStream:
exporter.exportReport();
output.flush();
output.close();
I hope that this works for you

Merging files into single pdf generate different view

I´m trying to merge into one file with one or more PDF files stored files and a JasperReports file using iText.
I did this method.
Map<String, Object> parameters = new HashMap<String, Object>();
List<String> arquivos = new LinkedList<String>();
arquivos.add("/Formulario/teste.jrxml");
arquivos.add("/Formulario/teste.pdf");
try {
Document document = new Document(PageSize.A4);
document.setMargins(0F, 0F, 0F, 0F);
PdfCopy pdfCopy = new PdfCopy(document, new FileOutputStream("c:\\labels\\teste.pdf"));
pdfCopy.setMargins(0, 0, 0, 0);
document.open();
PdfReader pdfReader = null;
InputStream inputStream = null;
for (String arquivo : arquivos) {
inputStream = ReportService.class.getResourceAsStream(arquivo);
if (FilenameUtils.getExtension(arquivo).equals("jrxml")) {
JasperReport report = JasperCompileManager.compileReport(inputStream);
JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameters, new JREmptyDataSource());
inputStream = new ByteArrayInputStream(JasperExportManager.exportReportToPdf(jasperPrint));
}
pdfReader = new PdfReader(inputStream);
for (int i = 1; i <= pdfReader.getNumberOfPages(); i++) {
pdfCopy.addPage(pdfCopy.getImportedPage(pdfReader, i));
}
pdfCopy.freeReader(pdfReader);
pdfReader.close();
}
document.close();
} catch (DocumentException | IOException | JRException e) {
e.printStackTrace();
}
I looked at google, but didn't found any answer. So whats wrong? It's possible to generate these pages in the same margins?
