How to correctly position a header image with docx4j?

I am trying to convert this Word document with a header showing an image on the right

http://www.filesnack.com/files/cduiejc7

to PDF using this sample code:

https://github.com/plutext/docx4j/blob/master/src/samples/docx4j/org/docx4j/samples/ConvertOutPDF.java

Here's the result:

While the Word document has the header image on the right, the converted PDF shows it on the left.

How can I make docx4j to reproduce the original document as PDF?

Solution

Your image is positioned relative to a paragraph:

      <w:drawing>
    <wp:anchor distT="0" distB="0" distL="114300" distR="114300" simplePos="0" relativeHeight="251658240" behindDoc="0" locked="0" layoutInCell="1" allowOverlap="1" wp14:anchorId="791936E3" wp14:editId="575B92C8">
      <wp:simplePos x="0" y="0"/>
      <wp:positionH relativeFrom="column">
        <wp:posOffset>5317388</wp:posOffset>
      </wp:positionH>
      <wp:positionV relativeFrom="paragraph">
        <wp:posOffset>-325755</wp:posOffset>
      </wp:positionV>

docx4j potential to support stuff like that in PDF output is limited by what XSL FO supports. See docx4j's TextBoxTest class for what we can do with text boxes.

Currently, although we can position some textBoxes; we don't do the same for floating images: https://github.com/plutext/docx4j/issues/127

In the meantime, a possible workaround for some cases (eg float right) is to use a table.

Or possibly, you could try putting the image inside a text box!
