Use this method to retrieve the locations of tagged visible
items. The locations are to be used with the value of Doc.Transform the same
as when the ID is obtained.
To use this method you need to enable the tagging functionality.
See the AddTags property
This function takes an ID obtained from a call to Doc.AddImageUrl, Doc.AddImageHtml or
and returns the locations of any items which are visible on the PDF
page as a result of that call.
The locations match up directly on a one-to-one basis with the
IDs returned by the GetTagIDs
