How do I rotate a page?

Q: How do I rotate a page?

A: To rotate a page in a document you can use the DocumentOperation API. Let’s say you want to rotate the first page of your document 90 degrees clockwise:

// Rotate the first page of the document 90 degrees clockwise
instance.applyOperations({
  type: "rotatePages",
  pageIndexes: [0],
  rotateBy: 90
});
