A representation of one or more content data streams in a PDF page.
- Core Graphics
CGPDFContent object represents one or more PDF content streams for a page and their associated resource dictionaries. A PDF content stream is a sequential set of instructions that specifies how to paint items on a PDF page. A resource dictionary contains information needed by the content stream in order to decode the sequential instructions of the content stream.
CGPDFContent functions can retrieve both the content streams and the resource dictionaries associated with a PDF page.
This type is not derived from
CFType and therefore there are no functions for retaining and releasing it.
CGPDFContent objects exist only as constituent parts of a
CGPDFDocument object, and they are managed by their container.
