Watermarks in a docx exported with JRDocxExporter

[pepelotas]

Hi!

I know the JRDocxExporter is a grid exporter and cells cannot be overlaped, however, if in a jasper template in the background band there is a watermark, it could be possible that the exporter exports al the bands except for the background one, and at the end set it in the docx document as a watermark.

The question is, is there a way to add some watermarks in an exported docx? A watermark that is a real watermark in the docx and even overlapping some content on top of it.

I have tryed but could not get it to work.

Can anyone help me, please?

Thanks in advance!
