Method Details
-
supportsPagesOutOfOrder
public boolean supportsPagesOutOfOrder()Indicates whether the painter supports to handle the pages in mixed order rather than ascending order.- Specified by:
supportsPagesOutOfOrder
in interfaceIFDocumentHandler
- Returns:
- true if out-of-order handling is supported
-
getMimeType
Returns the MIME type of the output format that is generated by this implementation.- Specified by:
getMimeType
in interfaceIFDocumentHandler
- Returns:
- the MIME type
-
getConfigurator
Returns the configurator for this document handler, if any.- Specified by:
getConfigurator
in interfaceIFDocumentHandler
- Returns:
- the configurator or null if there's no configurator
-
setDefaultFontInfo
Sets the default font set (with no custom configuration).- Specified by:
setDefaultFontInfo
in interfaceIFDocumentHandler
- Overrides:
setDefaultFontInfo
in classAbstractBinaryWritingIFDocumentHandler
- Parameters:
fontInfo
- the font info object to populate
-
getPCLUtil
PCLRenderingUtil getPCLUtil() -
getPCLGenerator
PCLGenerator getPCLGenerator() -
getResolution
protected int getResolution()- Returns:
- the target resolution
-
startDocument
Indicates the start of a document. This method may only be called once before any other event method.- Specified by:
startDocument
in interfaceIFDocumentHandler
- Overrides:
startDocument
in classAbstractBinaryWritingIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
endDocumentHeader
Indicates the end of the document header. This method is called before the first page sequence.- Specified by:
endDocumentHeader
in interfaceIFDocumentHandler
- Overrides:
endDocumentHeader
in classAbstractIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
endDocument
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 interfaceIFDocumentHandler
- Overrides:
endDocument
in classAbstractBinaryWritingIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
rewritePCLFile
- Throws:
IOException
-
copy
- Throws:
IOException
-
startPageSequence
Indicates the start of a new page sequence.- Specified by:
startPageSequence
in interfaceIFDocumentHandler
- Parameters:
id
- the page sequence's identifier (or null if none is available)- Throws:
IFException
- if an error occurs while handling this event
-
endPageSequence
Indicates the end of a page sequence.- Specified by:
endPageSequence
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
startPage
public void startPage(int index, String name, String pageMasterName, Dimension size) throws IFException Indicates the start of a new page.- Specified by:
startPage
in interfaceIFDocumentHandler
- Parameters:
index
- the index of the page (0-based)name
- the page name (usually the formatted page number)pageMasterName
- the name of the simple-page-master that generated this pagesize
- the size of the page (equivalent to the MediaBox in PDF)- Throws:
IFException
- if an error occurs while handling this event
-
startPageContent
Indicates the start of the page content. The method returns anIFPainter
interface which is used to paint the page contents.- Specified by:
startPageContent
in interfaceIFDocumentHandler
- Returns:
- the IFPainter for the page content
- Throws:
IFException
- if an error occurs while handling this event
-
createAllBitmapPainter
-
createBufferedImage
-
endPageContent
Indicates the end of the page content. Calls to theIFPainter
returned by the respectiveIFDocumentHandler.startPageContent()
method are illegal.- Specified by:
endPageContent
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
endPage
Indicates the end of a page- Specified by:
endPage
in interfaceIFDocumentHandler
- Throws:
IFException
- if an error occurs while handling this event
-
handleExtensionObject
Handles an extension object. This can be a DOM document or any arbitrary object. If an implementation doesn't know how to handle a particular extension it is simply ignored.- Specified by:
handleExtensionObject
in interfaceIFDocumentHandler
- Parameters:
extension
- the extension object- Throws:
IFException
- if an error occurs while handling this event
-
selectPageFormat
- Throws:
IOException
