The viewer selector is a special field that is used when using RIA to redact parts of the document pages. These fields must be used when redacting PII from documents.
PII detection logic in RIA finds is tasked with finding text that needs to be redacted. When it finds each text element it knows what the text was, and what its bounding rectangle co-ordinates and page number within the document are.
When the words requiring redaction are passed to the RIA page by the pre-processor that is performing PII searches, the RIA page places the word into a Viewer Selector and also keeps track of the page number and bounding rectangle co-ordinates.
When the user clicks on a Viewer Selector field on the RIA page, the viewer moves to the position of the PII word on the page and draws a highlight rectangle over it.
