Display our own logo image BI 4.1

Hello

I need to display a custom logo image on all reports. We are migrating from BO 3.1 to 4.1.

As per api, there is an option to set whether logo should be displayed or not (setHasLogo(true);), but i cannot find any method where custom image can be set.

Setting viewer.setHasLogo(true) in jsp does not have any difference on report displayed.

Please help.

Thanks & Regards,

Gaurav.
