Image not found for background-image attribute of block-container

问题

I have xslt template that generates pdf using Apache FOP. I have problem that background image cannot be found. I have tried absolute paths, relative paths and many else, but nothing happens. Could any of you help me ?

I have tried following paths, but it did not help. c:/Projects/demo/src/main/resources/certificate.png is absolute path

background-image="c:/Projects/demo/src/main/resources/certificate.png"
background-image="file:///c:/Projects/demo/src/main/resources/certificate.png"
background-image="certificate.png"
background-image="./certificate.png"
background-image="url(certificate.png)"
background-image="url(./certificate.png)"
background-image="url(c:/Projects/demo/src/main/resources/certificate.png)"
background-image="url(file:///c:/Projects/demo/src/main/resources/certificate.png)"
background-image="url(file:///./certificate.png)"

<fo:block-container position="absolute" height="210mm" width="297mm"
                                        background-image="c:/Projects/demo/src/main/resources/certificate.png"
                                        background-position="right" background-color="transparent">

                    </fo:block-container>

You need to use url() and wrap the URL in single quotes, like so:

<fo:block-container background-image="url('./certificate.png')" />
