Inserting Graphics in a Writer document

[Niklas Johansson]

If I were you I would set the Anchor before I insert the image into the 
document. So change the order of these lines:

     xText.insertTextContent(cursor, oGraphic, False)
     # Setting the anchor type - must be done first, otherwise the graphic will be put after the //
     oGraphic.AnchorType = AS_CHARACTER

Once the image is inserted into the document you won't always be able to 
change the anchor as you try to do in the code above. For some reason it 
works in your first example but as you can see it won't work in your 
second example.

So remember to always change the anchor of the graphic before you insert 
it otherwise you'll get more of these nice surprises. If I remember 
correctly there are a few more settings that should be done to the 
graphic object before it's inserted and some that needs to be set after, 
but I don't remember the details at the moment.

It seems that what is happening in the second case is that the image 
gets inserted before the anchor-change and when the re-anchoring occurs 
the image is already in the wrong position.

Niklas Johansson

The image is indeed anchored to this position, as I can see when I manually insert some more text before it. So it is not a matter of an offset.
