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.
