Change an image properties before the report generation [message #635451]

Hi,

I am generating a report using Report Engine classes and I would like to change the url of an image inserted in the report using BIRT Report Designer.

Is it possible to access this item and change its properties before the generation?

this is a sample of my code :

IReportEngine engine = null;
engine = Engine.getInstance().getEngine();
IReportRunnable design = null;
// Open the report design
try {
    design = engine.openReportDesign(report.getSource());
} catch (EngineException e) {
        LoggerBI.getInstance().fatal("", e);
        return false;
}
IRunAndRenderTask runtask = engine.createRunAndRenderTask(design);
ULocale lc = new ULocale(task.getLocale());
runtask.setLocale(lc);
runtask.setParameterValues(reportParams);
try {
     runtask.run();
} catch (EngineException e) {
     LoggerBI.getInstance().error("", e);
      return (false);
}
runtask.close();

Thanks!

Yes this is possible. You can also change it in script.

In Java like this:

ReportDesignHandle report = (ReportDesignHandle) design.getDesignHandle( );
ImageHandle myimage =(ImageHandle)report.findElement("MyImage1");
myimage.setURL("\"http://tomcat.apache.org/images/tomcat.gif\"");

In the above example note that the image element has been named in the
general properties for the image.

in Script

//beforeFactory script

var img1 =reportContext.getDesignHandle().findElement("MyImage1");
img1.setURL("\"http://tomcat.apache.org/images/tomcat.gif\"");
