I'm trying to add an image to odoo invoices as the company sign to all pages in the report, i'am added it by this way
<template id="durar_sale_order_sign_inv" inherit_id="account.report_invoice_document">
<xpath expr="//div[@id='qrcode']" position="after">
<div class="watermark" style="position:absolute;opacity:0.25;width:100%;heights:100%;z-index:4000;">
<img style="width:200px;heights:350px;text-align:right;border-radius: 50%;" t-attf-src="data:image/*;base64,{{o.sign_img}}"/>
</div>
</xpath>
</template>
I need it on every page in the report , so I tried this way
<template id="report_layout" inherit_id="web.external_layout_background">
<xpath expr="//div[hasclass('header')]" position="inside">
<div style="position:absolute;opacity:0.25;width:100%;heights:100%;z-index:4000;">
<img style="width:200px;heights:opacity:0.25;350px;text-align:right;border-radius: 50%;" t-attf-src="data:image/*;base64,{{o.sign_img}}"/>
</div>
</xpath>
</template>
but this put the image under the header in every page and it covered contents, so how can I place the image in right bottom and repeat it in every page
