Wikcet Freechart and SVG
Hi, i have some jfreechart generated images on my application. I did this
using an example on the wicket wiki. I wonder if i can do the same thing,
but sending an SVG image to the client. I have the svg generated by
jfreechar but now i dont know how can i use this on the html and on the Page
with wicket. Can anyone help me?
Thanks in advance.
Best regards.
Manuel.

Ahh okay, then you need to create a panel or something(maybe do it like
image itself just copy the source and make it attachable to embed) that
contains the embed...

Re: Wikcet Freechart and SVG
Posted by Manuel Corrales <ma...@gmail.com>.
Sorry for my stupidity :(
Ive tried your code, and as said before, the svg is being generated ok, but
it is not displayed on the browser (attached an image of the page). When i
right click on the broken image icon, and press save as, i can download the
svg.
For what i was reading, i dont think it is possible to include a svg image
in a <img> tag, i think only <embed> <object> and <iframe> can have an svg
image.
Anyway, i will keep looking for a solution.
Thanks!

I am going to try your code as soon as i can, but i still don't understand
where are you generating the svg image on this code.

Re: Wikcet Freechart and SVG
Posted by Nino Saturnino Martinez Vazquez Wael <ni...@jayway.dk>.
hmm whats JFreeChart image?
I usually do this, in my domain classes :
JFreeChart chart = ChartFactory
.createTimeSeriesChart(
Messages.getString("ReportWeightChart.5",
locale), Messages.getString("ReportWeightChart.6", locale),
Messages.getString("ReportWeightChart.7", locale), dataset, true, true,
false); //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$
return chart.createBufferedImage(500, 270);
And this in the wicket page :
Report simpleReport = (Report) item.getModelObject();
BufferedImage report = simpleReport.getReport(getLocale());
ImageResource imageResource = new ImageResource(report);
item.add(new Image("image", imageResource));
Ahh, I see you are mixing things(found the JFreeChart on the wiki).. You
cant do it like that it should be like this(although the otherway can
also be done):
JFreeChart chart = ChartFactory.createPieChart("Resumen de gastos",
dataSet, true, true, false);
PiePlot plot = (PiePlot) chart.getPlot();
plot.setSectionOutlinesVisible(false);
add(new Image("image",chart.createBufferedImage(640, 480)));

Re: Wikcet Freechart and SVG
Posted by Manuel Corrales <ma...@gmail.com>.
Here is the page code: (this is all prototype code, just messing around with
graphics on wicket)
JFreeChart chart = ChartFactory.createPieChart("Resumen de gastos",
dataSet, true, true, false);
PiePlot plot = (PiePlot) chart.getPlot();
plot.setSectionOutlinesVisible(false);
add(new Image("image",new JFreeChartImage("image", chart, 640,
480)));
Thanks a lot!!

Yes, i know, but i have tried with firefox and opera. Also to implement the
<object> solution i have to write the image to the disc first and then
dynamically set the data attribute on the object tag.
Nino: what do you mean by where is the page? If i can see a non SVG image
with exactly the same page, shouldn't i be able to see an SVG image?
Best regards.

Hey, great!! But still having issues, sorry to bother you again. Now i added
the svg to the page, but the browser do not display it. The image is there,
because when i right click the broken image that is displayed by the broser
and press save as, i can save the svg and is good. Should my html tag be
different, or should i set something else on my code:
....
private byte[] image;
public JFreeChartImage(String id, JFreeChart chart, int width, int
height) {
setFormat("svg");
try {
this.width = width;
this.height = height;
this.chart = chart;
DOMImplementation domImpl = GenericDOMImplementation
.getDOMImplementation();
Document document = domImpl.createDocument(null, "svg", null);
SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
chart.draw(svgGenerator,
new Rectangle2D.Double(0, 0, 1024, 768), null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Writer svgOutput;
svgOutput = new OutputStreamWriter(baos, "UTF-8");
svgGenerator.stream(svgOutput, true);
image = baos.toByteArray();
} catch (Exception e) {
image = new byte[0];
}
}
@Override
protected byte[] getImageData() {
return image;
}
and the html:
<img class="centrada" wicket:id="image" />
Thank you very much!!

instantiate a wicket image, with the resource.. It will not change the
format.. Just set the format to svg..

Thanks, but still dont get it. I did that, but now how can i add this image
to a page? The add method on page does not accept this DynamicImageResource.
Also, this will render the svg directly to the page? Or will transform it to
other format? (the documentation on DynamicImageResource only mention PNG,
JPG and GIF).
Thanks!

somewhat like this, and then just add the image as an image...:
import org.apache.wicket.markup.html.image.resource.DynamicImageResource;
public class ImageResource extends DynamicImageResource {
// has to save this. or get the image another way!
private byte[] image;
public ImageResource(byte[] image, String format) {
this.image = image;
setFormat(format);
}
public ImageResource(BufferedImage image) {

@Override

} else {
return new byte[0];
