/**

|
|
* <P>
|
|
* The marking operations for drawing a page are stored in a stream that is the value of the
|
|
* <B>Contents</B> key in the Page object's dictionary. Each marking context includes a list
|
|
* of the named resources it uses. This resource list is stored as a dictionary that is the
|
|
* value of the context's <B>Resources</B> key, and it serves two functions: it enumerates
|
|
* the named resources in the contents stream, and it established the mapping from the names
|
|
* to the objects used by the marking operations.<BR>
|
|
* This object is described in the 'Portable Document Format Reference Manual version 1.3'
|
|
* section 7.5 (page 195-197).
