All Implemented Interfaces:

DocListener, ElementListener, PdfAnnotations, PdfDocumentActions, PdfEncryptionSettings, PdfPageActions, PdfRunDirection, PdfVersion, PdfViewerPreferences, EventListener

public class PdfASmartCopy
extends PdfACopy

PdfASmartCopy has the same functionality as PdfACopy, but when resources (such as fonts, images,...) are encountered, a reference to these resources is saved in a cache, so that they can be reused. This requires more memory, but reduces the file size of the resulting PDF document.
