A parser object for handling content and operators in a PDF content stream.
Framework
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. Use CGPDFScanner and CGPDFScanner to manage the retain count of CGPDFScanner instances; do not use CFRetain and CFRelease.
