/**

* Resource extractor class is used to detach resources from original PDF document.
|
|
*
|
|
* It provides resources sharing, so different pages or other PDF resources can share
|
|
* its dependent resources (e.g. fonts or images) or other resources still use them without duplication.
|
|
* It also reduces output PDF size, required memory for PDF processing and
|
|
* processing time.
|
|
*
|
|
* The same extractor may be used for different source documents, several
|
|
* extractors may be used for constracting one target document, but extractor
|
|
* must not be shared between target documents.
