How not apply page margins on the background image in JasperSoft Studio? - jasper-reports

Question

I have TIBCO Jaspersoft® Studio 6.8.0.
My report has a background image. When I set page margins to i.e 20mm, it's applied to everything on the page(bands and background). I need to apply the margins to everything on the page except for the background so the background covers all the page including margins and the bands start printing after the page margins. Can this be accomplished?

Answer 1

No, you cannot have different margins on different bands.
Since you need the background image to be without margins you need to set the margins to 0 and then use as top margin the pageHeader band, bottom margin the pageFooter band*. The left and right margin are achieved by moving and sizing text elements.
The x position will be x=margin and width=pageWidth-2xmargin

</jasperReport>
* If you are using summary band, make sure that isSummaryWithPageHeaderAndFooter="true", as in example to get the top and bottom margins also on the summary band.
