Iam working on adding Watermark to a docx document using docx4j apis.Here is my code
The w:p node formed with v:shapetype and v:shape node are complete , except that Iam unable to set the r:id attribute in v:imagedata inside v:shape node.

<v:shape o:spid="_x0000_s2052" style="position:absolute;margin-left:0;margin-top:0;width:468pt;height:351pt;z-index:-251656192;mso-position-horizontal:center;mso-position-horizontal-relative:margin;mso-position-vertical:center;mso-position-vertical-relative:margin" type="#_x0000_t75" id="WordPictureWatermark775137986"><v:imagedata o:title="watermark" id="2"/></v:shape>

How can I add r:id attribute to v:imagedata node.Can someone help me on this?.

Thanks in Advance,
Krithi.

am unable to set the r:id attribute in v:imagedata inside v:shape node.

Interesting one. CTImageData contains:

Code: Select all

    public Map<QName, String> getOtherAttributes() {
        return otherAttributes;
    }


That's where you put it.

The reason for this is that imagedata is defined as follows in vml.xsd:

Code: Select all

  <xsd:element name="imagedata" type="CT_ImageData" />^M

  <xsd:complexType name="CT_ImageData">^M
    <xsd:sequence>^M
      <xsd:any processContents="strict" namespace="##other" minOccurs="0" maxOccurs="unbounded" />^M
    </xsd:sequence>^M
    <xsd:attribute name="id" type="xsd:string" use="optional" />^M
    <xsd:attribute name="src" type="xsd:string" use="optional" />^M
    <xsd:attribute name="cropleft" type="ST_Float" use="optional" />^M
    <xsd:attribute name="croptop" type="ST_Float" use="optional" />^M

  </xsd:complexType>^M



Note the xsd:anyAttribute, which is how r:id is allowed.

By the way, are you aware of XmlUtils.unmarshalString(String str), which is a quick way to make a JAXB object for say w:p from a string of XML? You can obtain the string of XML by saving a Word document containing the structure you want as .xml. Make sure all namespaces are declared within the snippet.

Thanks for such a swift response.It worked perfectly.

Thanks,
