Images and Unique Identifiers

[LokiTC]

I am inserting images in my docs, as per the example shown in AddImage.java:

Code: Select all

BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(_package, bytes);
Inline inline = imagePart.createImageInline(null, null, id1, id2, false);

// Now wrap the inline in w:p/w:r/w:drawing
P p = _objFactory.createP();
R run = _objFactory.createR();      
p.getParagraphContent().add(run);       
org.docx4j.wml.Drawing drawing = _objFactory.createDrawing();      
run.getRunContent().add(drawing);      
drawing.getAnchorOrInline().add(inline);
      
_documentPart.addObject(p);


My question is, for the create image inline call, id1 & 2 are supposed to be unique ids:

id1 - An id unique in the document
id2 - Another id unique in the document

So, is there a class/method somewhere to query what the next available IDs are? Or do have to track / figure it out manually?

Does it matter if they are not unique? In the example the same values for id1 & 2 are reused several times.

Thanks,

LokiTC

They don't matter for most purposes, but its been a while since I looked into that, so I don't recall their significance (surely they have some purpose..).

There is no class/method to query what the next available IDs are.

You can research them more if you use the search menu above to search documentinteropinitiative.
