将BufferedImage添加到PDFBox文档

感谢您帮助我解决垃圾问题。昨晚和今天花了几个小时，人们对PipedIn /
OutStreams感到困惑。无法解决。但是，我得到它的工作。事实证明，这并不是很困难。

public void exportToPDF(JFreeChart chart, String filePath){    PDdocument doc = null;    PDPage page = null;    PDXObjectImage ximage = null;    try {        doc = new PDdocument();        page = new PDPage();        doc.addPage(page);        PDPageContentStream content = new PDPageContentStream(doc, page);        //create a new outStream        ByteArrayOutputStream out = new ByteArrayOutputStream();        ChartUtilities.writeChartAsJPEG(out, chart, 300, 300);//write to outstream        //create a new inputstream        InputStream in = new ByteArrayInputStream(out.toByteArray());        ximage = new PDJpeg(doc, in);        content.drawImage(ximage, 5, 300);        content.close();    }    catch (IOException ie){        //handle exception    }    //save and close    doc.save(filePath);    doc.close();}

我敢肯定，这样做可以做得更好，但是可以。
