An object representing content within a PDF document.
- Core Graphics
PDF supports several basic types of object: Boolean values, integer and real numbers, strings, names, arrays, dictionaries, and streams. Most of these are represented in Core Graphics by corresponding specific types. A CGPDFObject can represent any of these types. You use CGPDFObject functions to determine the type of the object, and retrieve the object value if it is of an expected type.
This object is not derived from CFType and therefore there are no functions for retaining and releasing it. CGPDFObject objects exist as constituent parts of a CGPDFDocument object, and are managed by their container.
