From 40870db0aadef4e145fd3b2b95fa5a083afb3161 Mon Sep 17 00:00:00 2001 From: Diana Gage Date: Wed, 19 Jul 2017 18:16:03 -0700 Subject: Add FPDFAnnot_GetFormFieldAtPoint() and embedder tests. Given a point on a page, this method returns the interactive form annotation whose rectangle contains that point. If there is no such annotation, nullptr is returned. FPDFPage_CloseAnnot() must be called after the annotation this method returns is no longer needed. The tests for this method use the returned annotation to check its interactive form annotation flags via FPDFAnnot_GetFormFieldFlags().
