In order to answer your question, I added a watermark (choosing picture) to a document in Word 2007, then saved it as XML, then had a look at it in an XML editor (XPontus).

I found that Word added:

Code: Select all

                    <w:sectPr>
                        <w:headerReference w:type="even" r:id="rId6"/>
                        <w:headerReference w:type="default" r:id="rId7"/>
                        <w:footerReference w:type="even" r:id="rId8"/>
                        <w:footerReference w:type="default" r:id="rId9"/>
                        <w:headerReference w:type="first" r:id="rId10"/>
                        <w:footerReference w:type="first" r:id="rId11"/>


with each of the 3 headerReference having a rel pointing to the image "/word/media/image1.jpeg" (a jpeg in this case).

For example:

Code: Select all

    <pkg:part pkg:name="/word/_rels/header1.xml.rels" pkg:contentType="application/vnd.openxmlformats-package.relationships+xml">
        <pkg:xmlData>
            <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
                <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="media/image1.jpeg"/>
            </Relationships>
        </pkg:xmlData>
    </pkg:part>


to be continued ...

There are 2 ways you can get the image part.

The first is to get one of the header parts, then ask it for the image part by relationship type. Search this forum for posts on how to get the header part. Then:

Code: Select all

RelationshipsPart rp = headerpart.getRelationshipsPart();
Relationship rel = rp.getRelationshipByType(Namespaces.IMAGE);


Once you have the rel, you can do:

Code: Select all

BinaryPart p = (BinaryPart)rp.getPart(rel);

or, for example

Code: Select all

ImageJpegPart p = (ImageJpegPart)rp.getPart(rel);

The second, only if you already know the name of the part, is to get it directly from the parts collection. For a JPEG, something like:

Code: Select all

ImageJpegPart p = (ImageJpegPart)wordMLPackage.getParts().get(new PartName("/word/media/image1.jpeg" ) )

Look in the samples dir for basics such as how to load the wordMLPackage from a file.

Hi jason ,
Thanks a lot.I can able to proceed till Imagepart. Is it possible to get image as a file after that ?.so that i can do my process on that image.

Assuming BinaryPart p and target File f:

Code: Select all

               FileOutputStream fos = new FileOutputStream( f );
               ((BinaryPart)p).writeDataToOutputStream(fos);
               fos.close();
