-
startDocumentHeader
public void startDocumentHeader() throws IFException
Indicates the start of the document header. This method is called right after theIFDocumentHandler.startDocument()
method. Extensions sent to this painter betweenIFDocumentHandler.startDocumentHeader()
andIFDocumentHandler.endDocumentHeader()
apply to the document as a whole (like document metadata).- Specified by:
startDocumentHeader
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
endDocumentHeader
public void endDocumentHeader() throws IFException
Indicates the end of the document header. This method is called before the first page sequence.- Specified by:
endDocumentHeader
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
startPageSequence
public void startPageSequence(java.lang.String id) throws IFException
Indicates the start of a new page sequence.- Specified by:
startPageSequence
in interfaceIFDocumentHandler

IFException
- if an error occurs while handling this event
-

endDocument
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
