[two A5 in one A4]

Hi,

I have the same problem, I solved doing this:

 

 

JasperDesign jd = JRXmlLoader.load(ResourceUtils.getFile(getFileResourcesJRXML("myjasper_A5.jrxml")));

JasperReport jrRH02 = JasperCompileManager.compileReport(jd);

jp = JasperFillManager.fillReport(jrRH02, data, dataSource);

 

getResponse().setContentType("application/pdf");

ServletOutputStream outputStream = getResponse().getOutputStream();

ByteArrayOutputStream baos = new ByteArrayOutputStream();

JRPdfExporter exporter = new JRPdfExporter();

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT, jp);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, baos);

exporter.exportReport();

 

exporter.reset();

exporter = null;

System.gc();

 

Document document = new Document();

document.setPageSize(new Rectangle(jp.getPageWidth(), jp.getPageHeight() * 2)); // This is because A4 Size == 2 * A5

PdfReader pdfReader = new PdfReader(baos.toByteArray());

PdfWriter writer = PdfWriter.getInstance(document, outputStream);

document.open();

PdfContentByte cb = writer.getDirectContent();

for(int i = 1; i <= pdfReader.getNumberOfPages(); i++){

document.newPage();

PdfImportedPage page = writer.getImportedPage(pdfReader, i);

cb.addTemplate(page, 0, 0);

cb.addTemplate(page, 0, jp.getPageHeight());

}

 

outputStream.flush();

document.close();
