Hello,
I've searched the forum and can't find any information regarding this, so maybe someone can help me. I've added an image and a pagenumber to my footer, however, I need to be able to get the image to sit behind the pagenumbers. I tried to edit my word doc to see how word is handling it, and it seems it converts the inline image to an anchor image somehow. I don't want the image to be a link, I need it embedded. When I tried to add the image as an anchor, nothing happens, but I think that is due to me not linking the image to the anchor correctly. I've attached an example of what my footer looks like. Below is my code, any help is much appreciated:

In your working example, you have:



Per the spec:

drawing objects can exist in two states:

Inline - The drawing object is in line with the text, and affects the line height and layout of its line (like a character glyph of similar size).

Floating - The drawing object is anchored within the text, but can be absolutely positioned in the document relative to the page.

You need this floating type (ie wp:anchor), with @behindDoc="1", and



The language is a bit confusing; both wp:inline and wp:anchor images can be linked or embedded; that is controlled by whether a:blip has a @r:embed or @r:link.

docx4j's BinaryPartAbstractImage class only creates wp:inline images (as opposed to wp:anchor images). This would be worth enhancing.

In the absence of that, you can create the wp:anchor in several ways; the easiest might be using XmlUtils.unmarshalString or unmarshallFromTemplate (which is what BinaryPartAbstractImage does for wp:inline).

You may find this useful.

The xml contents of an inline element are similar to a lot of the elements inside an anchor element. The anchor contains those, and goes on to specify extra positional information.

So, rather than create an anchor from scratch, I used createImageInline to create an inline object and then marshall/unmarshalled this object into an anchor object. From here I can add the positional parameters.

Code: Select all

    BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, sourcePart, bytes);

    Inline inline = imagePart.createImageInline(filenameHint, altText, id1, id2, false);

    // convert the inline to an anchor (xml contents are essentially the same)
    String anchorXml = XmlUtils.marshaltoString(inline, true, false, Context.jc, Namespaces.NS_WORD12, "anchor",
        Inline.class);

    org.docx4j.dml.ObjectFactory dmlFactory = new org.docx4j.dml.ObjectFactory();
    org.docx4j.dml.wordprocessingDrawing.ObjectFactory wordDmlFactory = new org.docx4j.dml.wordprocessingDrawing.ObjectFactory();

    Anchor anchor = (Anchor) XmlUtils.unmarshalString(anchorXml, Context.jc, Anchor.class);
    anchor.setSimplePos(dmlFactory.createCTPoint2D());
    anchor.getSimplePos().setX(0L);
    anchor.getSimplePos().setY(0L);
    anchor.setSimplePosAttr(false);
    anchor.setPositionH(wordDmlFactory.createCTPosH());
    anchor.getPositionH().setAlign(STAlignH.RIGHT);
    anchor.getPositionH().setRelativeFrom(STRelFromH.MARGIN);
    anchor.setPositionV(wordDmlFactory.createCTPosV());
    anchor.getPositionV().setPosOffset(HEADER_TOP_OFFSET);
    anchor.getPositionV().setRelativeFrom(STRelFromV.PAGE);
    anchor.setWrapNone(wordDmlFactory.createCTWrapNone());

    // Now add the inline in w:p/w:r/w:drawing
    org.docx4j.wml.Drawing drawing = getObjectFactory().createDrawing();
    R run = getObjectFactory().createR();
    run.getContent().add(drawing);

    drawing.getAnchorOrInline().add(anchor);
   
    return run;


Note: from memory, I needed to specify the simple pos coordinates, even though I disabled simple pos via setSimplePosAttr(false)/

Hope this makes it simpler.
