Hi Andrew,
Thank you for your answer. In fact I want to create a numbered caption (something like « Figure 1 : my nice caption ») under an
inserted image and I want to create a table of figure with these captions to list all images.
-
The image is well inserted
-
The Table Of Figure is created and works fine when I add manually an image with a caption in the generated document.
-
This table of Figure doesn’t work for the image inserted programmatically, probably, because I don’t know how to create properly
a numbered caption.
I’m a bit confused about the SetExpression, DependentField, field master, … I will continue to investigate about that, but if you have
some references for me, please don’t hesitate.
Regards,
/Vincent Lorenzo

Objet : RE: need help to insert an image with a caption with the Libo java API <text:sequence-ref instead of <text:sequence
Are you looking to insert the caption, or the reference to the caption? I think you want to insert a reference to a dependent field for a text field master. Does this sound correct?
The text field master, which is of type:
com.sun.star.text.fieldmaster.SetExpression.Figure
But you want to reference a Dependent field. If my guess is correct, this is how I insert a reference to the first Figure using Basic. Note that there is almost no error checking, so, this could go very wrong.
Sub Main
Dim oField
Dim oNewField
Dim oText
Dim oCurs
Dim oReferencedField
Dim oEnum
Dim oDispatcher ' Dispatcher object.
Dim oFrame
' Setup to perform a dispatch.
oFrame = ThisComponent.CurrentController.Frame
oDispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
oText = ThisComponent.getText()
oCurs = ThisComponent.CurrentController.getViewCursor()
oEnum = ThisComponent.getTextFields().createEnumeration()
If Not IsNull(oEnum) Then
Do While oEnum.hasMoreElements()
oField = oEnum.nextElement()
'Inspect oField
If oField.supportsService("com.sun.star.text.TextField.SetExpression") Then
If oField.VariableName = "Figure" Then
Print "Found one"
Exit Do
End If
End If
Loop
End If
' No error checking, I just assume that I found one. DANGER DANGER DANGER
_oNewField_ = ThisComponent.createInstance("com.sun.star.text.textfield.GetReference")
oNewField.ReferenceFieldPart = com.sun.star.text.ReferenceFieldPart.CATEGORY_AND_NUMBER
oNewField.ReferenceFieldSource = com.sun.star.text.ReferenceFieldSource.SEQUENCE_FIELD
oNewField.SequenceNumber = oField.SequenceValue
oNewField.SourceName = "Figure"
oText.insertTextContent(oCurs, oNewField, True)
' This next part will NOT work until after all of the fields have updated.
' So, force an update.
oDispatcher.executeDispatch(oFrame, ".uno:UpdateFields", "", 0, Array())
End Sub

Hello everybody,
Since my last question, I switched task. Now I come back to my LibreOffice task to resolve my caption problem.
I'm still blocked on this problem. I get a different result compared to my last email, but the reference for the caption is still not found.
I replace Illustration by Figure, but the problem keeps the same.
I obtain a text:sequence-ref instead of a text:sequence. Does someone know why or which is the API to use to generate a text:sequence...
My result for the numbering of the caption:
<text:sequence-ref text:reference-format="value" text:ref-name="refFigure0">Erreur : source de la référence non trouvée</text:sequence-ref> (the french text said "reference not found")
I would like to get :
<text:sequence text:ref-name="refFigure0" text:name="Figure" text:formula="ooow:Figure+1" style:num-format="1">1</text:sequence>
My java code for that :
Object oReference = xMultiServiceFactory.createInstance("com.sun.star.text.textfield.GetReference");
XPropertySet oReferencePropertySet = UnoRuntime.queryInterface(XPropertySet.class, oReference);
oReferencePropertySet.setPropertyValue("SourceName", "Figure");// I get <text:sequence-ref
oReferencePropertySet.setPropertyValue("ReferenceFieldPart", ReferenceFieldPart.ONLY_SEQUENCE_NUMBER);
oReferencePropertySet.setPropertyValue("ReferenceFieldSource", ReferenceFieldSource.SEQUENCE_FIELD);
oReferencePropertySet.setPropertyValue("SequenceNumber", 0);// (short) 2);//not requireed ?
XTextContent xRef = UnoRuntime.queryInterface(XTextContent.class, oReference);
localCursor.getText().insertTextContent(localCursor, xRef, false);

Objet : [PROVENANCE INTERNET] RE: need help to insert an image with a caption with the Libo java API
Hello everybody,
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 [1], the expect xml structure [2] and the current xml structure [3].
I know I have some difference between [2] and [3] with the width/height properties and inside the draw frame, but it is not the subject of this thread.
[1] insertImage.java
[2] expectedResult.xml
[3] currentResult.xml
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...<
Best regards,

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.
