CGPDFScanner

Overview

You can set up the PDF scanner object to invoke callbacks when it encounters specific PDF operators in the stream.

This object is not derived from CFType. In Objective-C, use CGPDFScannerRetain(_:) and CGPDFScannerRelease(_:) to manage the retain count of CGPDFScannerRef instances; do not use CFRetain and CFRelease.
