public PSDocumentHandler(IFContext context)
Default constructor.

Method Detail

supportsPagesOutOfOrder

public boolean supportsPagesOutOfOrder()
Indicates whether the painter supports to handle the pages in mixed order rather than ascending order.

Returns:
true if out-of-order handling is supported

getMimeType

public java.lang.String getMimeType()
Returns the MIME type of the output format that is generated by this implementation.

Returns:
the MIME type

getConfigurator

public IFDocumentHandlerConfigurator getConfigurator()
Returns the configurator for this document handler, if any.

Returns:
the configurator or null if there's no configurator

getPSUtil

public PSRenderingUtil getPSUtil()

startDocument

public void startDocument()
                   throws IFException
Indicates the start of a document. This method may only be called once before any other event method.

Specified by:
startDocument in interface IFDocumentHandler
Overrides:
startDocument in class AbstractBinaryWritingIFDocumentHandler
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 interface IFDocumentHandler
Overrides:
endDocumentHeader in class AbstractIFDocumentHandler
Throws:
IFException - if an error occurs while handling this event

endDocument

public void endDocument()
                 throws IFException
Indicates the end of a document. This method may only be called once after the whole document has been handled. Implementations can release resources (close streams). It is an error to call any event method after this method.

Specified by:
endDocument in interface IFDocumentHandler
Overrides:
endDocument in class AbstractBinaryWritingIFDocumentHandler
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.

Parameters:
id - the page sequence's identifier (or null if none is available)
Throws:
IFException - if an error occurs while handling this event

endPageSequence

public void endPageSequence()
                     throws IFException
Indicates the end of a page sequence.

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

startPage

public void startPage(int index,
                      java.lang.String name,
                      java.lang.String pageMasterName,
                      java.awt.Dimension size)
               throws IFException
Indicates the start of a new page.

Parameters:

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

startPageHeader

public void startPageHeader()
                     throws IFException
Indicates the start of the page header.

Specified by:
startPageHeader in interface IFDocumentHandler
Overrides:
startPageHeader in class AbstractIFDocumentHandler
Throws:
IFException - if an error occurs while handling this event

endPageHeader

public void endPageHeader()
                   throws IFException
Indicates the end of the page header.

Specified by:
endPageHeader in interface IFDocumentHandler
Overrides:

startPageContent

public IFPainter startPageContent()
                           throws IFException
Indicates the start of the page content. The method returns an IFPainter interface which is used to paint the page contents.

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

startPageTrailer

public void startPageTrailer()
                      throws IFException
Indicates the start of the page trailer. The page trailer is used for writing down page elements which are only know after handling the page itself (like PDF targets).

Specified by:
startPageTrailer in interface IFDocumentHandler
Overrides:
startPageTrailer in class AbstractIFDocumentHandler
Throws:
IFException - if an error occurs while handling this event

endPageTrailer

public void endPageTrailer()
                    throws IFException
