Store rotation

[KillerCodeMonkey]

Before you start - checklist

• I understand that React-PDF does not aim to be a fully-fledged PDF viewer and is only a tool to make one
• I have checked if this feature request is not already reported

Description

Currently we are using this wonderful and easy to use lib to show existing pdfs - which works great!

But we have an option to rotate each page.
Now it would be nice to get the new pdf data back when using the "saveDocument or "getData" methods, so we can somehow store that rotation by uploading the changed pdf again :).

Proposed solution

saveDocument or getData should return the data of the currently visible pdf with all "changes" made by transformations/rotations that the lib already supports.
I know this is not possible that easy, because even pdfjs does not saves rotations.

Sorry, where are these methods coming from? Do you have a code example (might be non functional) of you're trying to achieve?

[KillerCodeMonkey]

Currently, I am sick, but i am using those methods coming from the document instance I get when listening to "onLoadSuccess".

On the frontendside, we implemented some rotation buttons per page or the whole document.

As workaround, we are storing the rotations per page and passing them to the backend, which applies the rotation per page and uploads the file to s3.

But I have to recheck it again. It might be an implementation issue, where we passed 0 as default rotation, because we thought after rotating the page and uploading the file, the rotation is 0 again per default. If this makes sense.

But it seems the page is not really (natively?!) rotated, since after setting the default rotation to 0, it rotates it back.

Thanks for your feedback!

Ohhh. Well, this package does not support saving PDFs. Rotate prop, similarly to width, height props, just changes the way existing PDF displays.

[KillerCodeMonkey]

Yes, i retested it again. getData and save just returns the original file and not the possible changed :).

Thanks for the fast answers.

you can decide what you (not) want to do with that enhancement :).
