Change image url before run task

frenchGuy

Hi,<br />
<br />
I am generating a report using a Report Engine classes and I would like to change the url of an image inserted in the report using BIRT Report Designer.<br />
<br />
Is it possible to access this item and change its properties before the generation?<br />
<br />
this is a sample of my code :<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
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();

</pre>
<br />
Thanks!

Yes this is possible.

The IReportRunnable interface has a method called getDesignHandle() this method gives you a reference to the ROM of your report. You can use it to access the representation of any object in the report you loaded.

Simply add
imageHandle = design.getDesignInstance().getImage("myImage");
imageHandle.setURL("My new URL");

One last thing to do:
Open your report and name the image you want to change myImage
