Calixte Denizet	ddba096191	Make tagged images visible for screen readers (bug 1708040) ... The idea is to insert a span in the text layer with an aria-role set to img and use the bounding box provided by the attribute field in the tag dict in order to have non-null dimensions for the image to make it "visible".	2024-09-05 17:59:42 +02:00
Jonas Jenwald	971ac8e993	Include the /Lang-property, when it exists, in the StructTree-data (issue 14261) ... *Please note:* This is a tentative patch, since I don't have the necessary a11y-software to actually test it.	2021-11-14 12:37:41 +01:00
Brendan Dahl	fc9501a637	Add support for basic structure tree for accessibility. ... When a PDF is "marked" we now generate a separate DOM that represents the structure tree from the PDF. This DOM is inserted into the <canvas> element and allows screen readers to walk the tree and have more information about headings, images, links, etc. To link the structure tree DOM (which is empty) to the text layer aria-owns is used. This required modifying the text layer creation so that marked items are now tracked.	2021-04-09 09:56:28 -07:00
