flush
public void flush(boolean flushResourcesContentStreams)
Description copied from class:PdfPage
Flushes page dictionary, its content streams, annotations and thumb image. IfflushResourcesContentStreams
is true, all content streams that are rendered on this page (like FormXObjects, annotation appearance streams, patterns) and also all images associated with this page will also be flushed.For notes about tag structure flushing see
PdfPage#flush() method
.If
PdfADocument
is used, flushing will be applied only ifflushResourcesContentStreams
is true.Be careful with handling document in which some of the pages are flushed. Keep in mind that flushed objects are finalized and are completely written to the output stream. This frees their memory but makes it impossible to modify or read data from them. Whenever there is an attempt to modify or to fetch flushed object inner contents an exception will be thrown. Flushing is only possible for objects in the writing and stamping modes, also its possible to flush modified objects in append mode.
