Exporting to image

[njrfrens]

How can I export the chart output of .jasper result as an image?

We have exporters like JRHtmlExporter,pdf,xls,xml etc. but couldn't find any exporter for image. Why is it so?

if not image, atleast can I get the byte array of the result of .jasper? so that I'll convert the byte stream to image...

Assuming you already have the jasperprint object

 

 

 

Code:

			        	response.setContentType("image/jpeg");			        				        	BufferedImage pageImage = new BufferedImage(jasperPrint.getPageWidth() + 1, jasperPrint.getPageHeight() + 1, BufferedImage.TYPE_INT_RGB);			        				        	exporter = new JRGraphics2DExporter();			        	exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);			        			                Map imagesMap = new HashMap();		        				                request.getSession().setAttribute("IMAGES_MAP", imagesMap);			        			                exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR, Boolean.FALSE);		                exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap);		                exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, context+"/images?image=");			        				        	exporter.setParameter(JRGraphics2DExporterParameter.GRAPHICS_2D, pageImage.getGraphics());			        	exporter.setParameter(JRExporterParameter.PAGE_INDEX, new Integer(0));			        				            exporter.exportReport();			            output = bufferedImageToByteArray(pageImage);	      public static byte[] bufferedImageToByteArray(BufferedImage img) throws IOException{	   	      ByteArrayOutputStream os = new ByteArrayOutputStream();	   	      JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(os);	   	      encoder.encode(img);	   	      return os.toByteArray();	   	      }
