PDFs with mixed page orientation display text vertically

PDF.js Express Plus

PDF.js Express Version

Detailed description of issue
We have a file with mixed page orientation: some are landscape, some are portrait. The text fields on the landscape pages appear just fine in Adobe Acrobat Pro with no edits needed on the field orientation. However when viewed and edited in pdfjs, the text is vertical.

Expected behaviour
The text field is presented with horizontal text to match the page orientation.

Does your issue happen with every document, or just one?
All documents with mixed page orientation

Code snippet

Hello Chris,

I was able to reproduce the issue of the vertical text on the landscape pages.
I have created a bug report and added this to our backlog.

Best Regards,

Thanks for checking Darian.

What workarounds can we do in the interim and what’s the ETC on a fix?

Hello Chris,

Unfortunately, I don’t think we have any workarounds for this issue at the moment. We don’t have an estimated time, but we will let you know.

Best Regards,

Hey Darian,

Any update on an ETA for this one? We tried also just a document all in landscape (thinking that it was the mix that was causing it) and it won’t work so we’re out of options. Anything we can do, even with javascript or something else?
