Rotate PDF Pages in UWP

Pages can be rotated in 90-degree intervals, either clockwise or counterclockwise, by using an Editor.Job:

// Make a job with a source document as its input.
var editorJob = new PSPDFKit.Document.Editor.Job(sourceDocument);

// Rotate the second page 90 degrees counterclockwise.
await job.RotatePageAsync(1, Rotation.DegreesNegative90);

// Generate a new document.
var newDocumentStorageFile = await PSPDFKit.Document.Editor.Editor.NewStorageFileFromJobAsync(editorJob);
