How to image stream to jasper report ?
It is very easy to pass image stream to jasper report pdf.
Steps are,
1) Convert the image to stream and set it in parameter ("logo")
2) In jrxml file , create a parameter with parameter class as "java.io.InputStream"
3) Place a image on the jrxml design, set "Image Expression" to $P{logo} and "Expression class" to java.lang.String
@Test
public void createPdfWithImageAsStream() {
try {
System.out.println("pdf report creation started .... ");
String outFileNamePDF = "/Users/user/Tried/POC/imageStreamToPdf/createPdfWithImageAsStream.pdf";
new File(outFileNamePDF).getParentFile().mkdirs();
String containerJrxmlFile = "/Users/user/Tried/POC/imageStreamToPdf/createPdfWithImageAsStream.jrxml";
// pass logo as stream.
Map<String, Object> parameters = new HashMap<String,Object>();
File img = new File("/Users/user/Desktop/wallpaper.jpg");
InputStream fis = new FileInputStream(img);
System.out.println("printnng");
parameters.put("logo", fis);
InputStream reportStream = new FileInputStream(containerJrxmlFile);
BufferedInputStream bufferedInputStream = new BufferedInputStream(reportStream);
JasperDesign jasperDesign = JRXmlLoader.load(bufferedInputStream);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileNamePDF);
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.exportReport();
System.out.println("pdf report created .... ");
} catch (Exception e) {
e.printStackTrace();
}
}
Happy coding :)
