JFreechart export to Powerpoint PPT

[paintool]

Is it possible to export a JFreechart chart to a Microsoft powerpoint slide?

[paradoxoff]

Yes.
Here a two methods that I quickly copied from one of my projects:
I am using apache POI for the powerpoint part and freehep VectorGraphics project to create the EMF file. "slideShow" is an instance of org.apache.poi.hslf.usermodel.SlideShow.

Code: Select all

    public void export(JFreeChart chart) throws Exception {
        ByteArrayOutputStream emfout = new ByteArrayOutputStream();
        EMFChartExporter ee = new EMFChartExporter(emfout);
        ee.exportChart(chart, width, height);
        int emfindex = slideShow.addPicture(emfout.toByteArray(), Picture.EMF);
        Picture emf = new Picture(emfindex);
        Slide slide = slideShow.createSlide();
        emf.setAnchor(new java.awt.Rectangle(25, 100, (int)(width * scalingFactor), (int)(height * scalingFactor)));
        slide.addShape(emf);
    }
public class EMFChartExporter{
    private OutputStream out;

    public EMFChartExporter(OutputStream out) {
        this.out = out;
    }

    public void exportChart(JFreeChart chart, int width, int height) throws IOException {
        EMFGraphics2D g2d = new EMFGraphics2D(this.out, new Dimension(width, height));
        g2d.setDeviceIndependent(true);//needs to be set, otherwise the export is lousy
        g2d.startExport();
        chart.draw((Graphics2D) g2d.create(), new Rectangle(width, height));
        g2d.endExport();
        g2d.closeStream();
    }
}

Thank's, it really works!! I thought I can import it like I usually import animated templates from http://www.pptstar.com/powerpoint/animated/, but it didn't work with Jfreechart

Hi,
I'm always used templates for PowerPoint from this site http://www.poweredtemplate.com/. Export will be working with these templates?
