CGPDFStream

A stream or sequence of data bytes in a PDF document.

Overview

A PDF stream consists of a dictionary that describes a sequence of bytes. Streams typically represent objects with potentially large amounts of data, such as images and page descriptions.

This object is not derived from CFType and therefore there are no functions for retaining and releasing it.
