Extract pages from PDFs on iOS
Nutrient’s Processor can extract pages from one document and put them in another document. You can choose to extract a single page, a range of pages, or even multiple page ranges.
In most cases, you’ll want to use Processor to create a new PDF document on disk based on a current Document. The example below shows how to flatten annotations and extract the first three pages in a document to another document on disk:
// Create a default configuration.let configuration = Processor.Configuration(document: document)!// Change all annotations to be flattened (instead of saved as annotations).configuration.modifyAnnotations(ofTypes: .all, change: .flatten)// Only extract pages 0, 1, and 2.configuration.includeOnlyIndexes(IndexSet(integersIn: 0...2))
// Start the conversion from `document` to `extractedURL`.let processor = Processor(configuration: configuration, securityOptions: nil)// Save to a new file on disk. Alternatively, you can use `output(to:)`// to save the resulting document to a custom data source.try processor.write(toFileURL: extractedURL)// Create a default configuration.PSPDFProcessorConfiguration *configuration = [[PSPDFProcessorConfiguration alloc] initWithDocument:document];// Change all annotations to be flattened (instead of saved as annotations).[configuration modifyAnnotationsOfTypes:PSPDFAnnotationTypeAll change:PSPDFAnnotationChangeFlatten];// Only extract pages 0, 1, and 2.[configuration includeOnlyIndexes:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, 2)]];
// Start the conversion from `document` to `extractedURL`.PSPDFProcessor *processor = [[PSPDFProcessor alloc] initWithConfiguration:configuration securityOptions:nil];// Save to a new file on disk. Alternatively, you can use `outputToDataSink:error:`// to save the resulting document to a custom data source.[processor writeToFileURL:extractedURL error:NULL];Similar functionality is also available via Document Editor. See the PDFDocumentEditor.exportPages(_:toPath:withCompletionBlock:) API documentation for more information.
