I think captions are just a UI feature. The doc model just stores a text
frame around the image and the image is followed by the caption itself.
(I.e. later it's not possible to reliably detect if some content around
an image in a frame was created by hand or using the captions UI code.)
So you can do the same "manually" using the UNO API. When in doubt, see
what UNO API the ODT import uses to create the doc model based on the
yep, insert a Frame, insert a Image in the frame and add a caption
oDoc = ThisComponent
oText = oDoc.getText()
oViewCursor = oDoc.getCurrentController().getViewCursor()
oReference = oDoc.createInstance("com.sun.star.text.textfield.GetReference")
.SourceName = "Illustration"
.ReferenceFieldPart = com.sun.star.text.ReferenceFieldPart.ONLY_SEQUENCE_NUMBER
.ReferenceFieldSource = com.sun.star.text.ReferenceFieldSource.SEQUENCE_FIELD
.SequenceNumber = 0
oText.insertTextContent(oViewCursor, oReference, False)
I thank you for your answers. Yes I want to add an image with a caption programmatically and I want a caption like this "Illustration 1 : My caption"
To my mind, it would be better/cleaner if I was able to generate the same thing than I do the UI. Thanks to you, I succeed to build the expected structure for the image and to set a text below it, but I still have some problems, mainly with the GetReference.
The GetReference generates :
<text:reference-ref text:reference-format="text" text:ref-name="refIllustration0">Erreur : source de la référence non trouvée</text:reference-ref> (sorry my Libo is in French, it is written "Sorry : source of the reference not found").
And I would like to get a text:sequence instead of a text:reference, to get this result:
<text:sequence text:ref-name="refIllustration0" text:name="Illustration" text:formula="ooow:Illustration+1" style:num-format="1">1</text:sequence>
Please, do you know how I can build a text:sequence ?
Please found in attachment the java code I wrote , the expect xml structure  and the current xml structure .
I know I have some difference between  and  with the width/height properties and inside the draw frame, but it is not the subject of this thread.
In addition, I have more generic question, do you know if it exists a documentation, indicating mapping, between the xml elements and how to get/create them from java ? For example, in xml svg:width is called Height in the java API, and my Textframe becomes <draw:text-box...<

And actually, if an image is not intended to be floating, but (as seen in majority of cases) is a part of normal text flow, then the frame could be not needed at all - simply add an image anchored as character, then add a paragraph with required style and numbering range field, then continue with other paragraphs. This makes the document structure clearer. Just an advise based on own experience.
