Method Detail

processPageContent

public void processPageContent(com.itextpdf.kernel.pdf.PdfPage page)

Overrides:

processPageContent in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

processPageAnnotations

public void processPageAnnotations(com.itextpdf.kernel.pdf.PdfPage page,
                                   List<com.itextpdf.kernel.geom.Rectangle> regions,
                                   boolean redactRedactAnnotations)

Process the annotations of a page. Default process behaviour is to remove the annotation if there is (partial) overlap with a redaction region

Parameters:

page - the page to process

regions - a list of redaction regions

redactRedactAnnotations - true if annotation with subtype /Redact should also be removed

processContent

public void processContent(byte[] contentBytes,
                           com.itextpdf.kernel.pdf.PdfResources resources)

Overrides:

processContent in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

Parameters:

contentBytes - the bytes of a content stream

resources - the resources of the content stream. Must not be null.

getEventListener

public com.itextpdf.kernel.pdf.canvas.parser.listener.IEventListener getEventListener()

Overrides:

getEventListener in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

                              List<com.itextpdf.kernel.pdf.PdfObject> operands)

Overrides:

invokeOperator in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

beginMarkedContent

protected void beginMarkedContent(com.itextpdf.kernel.pdf.PdfName tag,

Overrides:

beginMarkedContent in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

eventOccurred

protected void eventOccurred(com.itextpdf.kernel.pdf.canvas.parser.data.IEventData data,
