Changing the printed area of a book title page

Hi,

I would like the first page of my book to display an image that would
cover as much of the page as possible.

I customized fo/titlepage.templates.xml as follows:

   <t:titlepage t:element="book" t:wrapper="fo:block">

    <t:titlepage-content t:side="recto">      

     <mediaobject/>

    </t:titlepage-content>

and I used the following in the bookinfo
section:

  <mediaobject>

    <imageobject role="pdf">

    <imagedata  align="center" format="SVG"
fileref="cover-image.svg"/>

   </imageobject>  

  </mediaobject>

The parameters to specify the page layout
are:

 <xsl:param
name="page.height.portrait">11in</xsl:param>

 <xsl:param name="page.width.portrait">8.5in</xsl:param>

 <xsl:param name="page.margin.top">0.75in</xsl:param>

 <xsl:param name="page.margin.bottom">0.50in</xsl:param>

 <xsl:param name="page.margin.inner">1.00in</xsl:param>

 <xsl:param name="page.margin.outer">1.00in</xsl:param>

When I try to generate the pdf file (using xep) I have the following
error message:

[error] no space for an element, trying to recover

[error] no space for an element, trying to recover

The size of my image is 6.4x9.7 inches, which should fit. I tried to
reduce the image, and the maximum size I can fit is 5.56x8.375 inches.
What am I missing?
