How to apply texture pattern to 3D bars in pdf generated using iReport?

I have a requirement like applying texture pa开发者_开发知识库ttern to the 3D bars in 3D Barchart using ireport. I am able to see the texture pattern in the default JRViewer. But when I take the PDF from the same report, I cannot see the texture pattern instead I can see a transparent 3D bars.

Can someone have a solution ?

with a little research we found the answer. There is an option in the iReport for the charts called renderType. We need to set this as svg(Scalable Vector Graphics). So the texture pattern will apply to the PDF also.

The disadvantage of using this is - The PDF file size gets increased.
