Default Reading Order

Post by gregorio.pellegrino » Fri Feb 08, 2019 1:30 pm

We have noticed that, using the SDK to get the text with which we make the text-to-speech, the default reading order is not interpreted correctly.

In the attached file I used the specifications of the PDF format (from Adobe Indesign) to force the reading order in 1-2-3-4 and this is correctly interpreted by Acrobat Pro.

PDF-XChange Viewer SDK, on the other hand, reads 4-2-3-1. Is this something that can be changed in the SDK API, or is it a bug?

Thank you,
