Extract Pages from PDFs in UWP

The following example shows how to use Editor.Job to produce a new document that keeps only pages 0 and 2 from a source document:

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

// Keep the first and third pages.
await editorJob.KeepPagesAsync(new int[]{ 0, 2 });

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

// Load this document into a `PdfView`.
PdfView.PdfFileSource = newDocumentStorageFile;
