Pdf-lib: Page rotation?

Created on 4 Jun 2019 · 2Comments · Source: Hopding/pdf-lib

I went through the documentation and source code. It seems we can't do page rotation right now. Is my understanding correct?

Hello @qingxiang-jia!

Page rotation is not currently documented, but it is certainly possible to do. It's quite straightforward:

import { PDFNumber } from 'pdf-lib';

const pdfDoc = ...
const firstPage = pdfDoc.getPages()[0];

// Rotate the first page by 180 degrees
firstPage.set('Rotate', PDFNumber.fromNumber(180));

Please let me know if you have any further questions!
