Key Object Reports and accessing image references

[canonrad]

If I have a key Object report or any SR, is there a way to parse out the image references? DSRDocument tree has the gotoNamedNode function, but I didn't think image references had names. I thought about using getNextNode of goToNext, but there is no guarantee that the node would be an image node.
Any suggestions?

You could e.g. use iterate() and then check the value type using getValueType().

The following code snippet from the dcmsr module shows how this approach basically works:

Code: Select all

void DSRDocumentTree::unmarkAllContentItems()
{
    DSRTreeNodeCursor cursor(getRoot());
    if (cursor.isValid())
    {
        DSRDocumentTreeNode *node = NULL;
        /* iterate over all nodes */
        do {
            node = OFstatic_cast(DSRDocumentTreeNode *, cursor.getNode());
            if (node != NULL)
                node->setMark(OFFalse);
        } while (cursor.iterate());
    }
}

Also see examples section in the documentation for how to access the content tree of an SR document.

Btw, I guess it could be useful to write a wrapper class for accessing Key Object Selection Documents or to write a new helper function similar to gotoNamedNode() that allows for going to nodes of a particular value type. This shouldn't be too difficult.
