Method Detail

preOpen
void preOpen(ITextRenderer iTextRenderer)
Called immediately after the iText Document instance is created but before the call toDocument.open()
is called. At this point you may still modify certain properties of the PDF document header via thePdfWriter
; once open() is called, you can't change, e.g. the version. See the iText documentation for what limitations there are at this phase of processing.- Parameters:
iTextRenderer
- the renderer preparing the document
-
preWrite
void preWrite(ITextRenderer iTextRenderer, int pageCount)
Called immediately before the pages of the PDF file are about to be written out. This is an opportunity to modify any document metadata that will be used to generate the PDF header fields (the document information dictionary). Document metadata may be accessed through theITextOutputDevice
that is returned byITextRenderer.getOutputDevice()
.- Parameters:
iTextRenderer
- the renderer preparing the documentpageCount
- the number of pages that will be written to the PDF document
-
onClose
void onClose(ITextRenderer renderer)
Called immediately before the iText Document instance is closed, e.g. beforecom.itextpdf.text.Document#close()
is called.- Parameters:
renderer
- the iTextRenderer preparing the document
