[birt-report-designer-dev] How to set a background picture in the rptdes

[Alexander Wang <Alexander.Wang@xxxxxxxxxxxxxxxxxx>]

Hi,  all,

I want to print a given invoice which is already been designed, then I 
want to take the following steps:
1) Firstly, I scan the invoice into a jpeg file
2) Secondly, I set the scaned jpeg file as the backgroud of the 
rptdesign file
3) Thirdly, drag the corresponding db fields into the corresponding 
blank the fields
4) Finally, I want to se the backgroud unvisible and print it. Of 
course, the given invoice is placed in the printer, thus the invoice can 
be printed.

But I come across a big question: now the BIRT support the backgroud 
picture?(see step 2 and step 4). If not, how can I relize this print 
function.

Thank you all,

Sincerely
Alexander
