From 002a6fee2fbd07c3f0cd1f1ddba39c691130727e Mon Sep 17 00:00:00 2001 From: Michael Stahl Date: Fri, 24 Mar 2023 18:45:53 +0100 Subject: tdf#152234 drawinglayer,svx: PDF/UA export: add Alt text to form controls Specification: ISO 14289-1:2014, Clause: 7.18.1, Test number: 3 A form field whose hidden flag is not set and whose rectangle is not outside the crop-box shall have a TU key present or all its Widget annotations shall have alternative descriptions (in the form of an Alt entry in the enclosing structure elements) Form controls are weird because they have an SdrObject with the usual name/title/description plus a property "HelpText" on the control itself which is already exported as "/TU" on the /Annot unless it's empty. Exporting the SdrObject properties via ObjectInfoPrimitive2D doesn't work as tragically that is only created for form controls when painting to the screen while PDF export takes a detour that needs special handling.
