Constructor Detail

PDDocument

public PDDocument()
           throws IOException

Constructor, creates a new PDF Document with no pages. You need to add at least one page for the document to be valid.

Throws:

IOException - If there is an error creating this document.

PDDocument

public PDDocument(COSDocument doc)

Constructor that uses an existing document. The COSDocument that is passed in must be valid.

Parameters:

doc - The COSDocument that this document wraps.

Method Detail

addPage

public void addPage(PDPage page)

This will add a page to the document. This is a convenience method, that will add the page to the root of the hierarchy and set the parent of the page to the root.

Parameters:

page - The page to add to the document.

removePage

public boolean removePage(PDPage page)

Remove the page from the document.

Parameters:

page - The page to remove from the document.

Returns:

true if the page was found false otherwise.

removePage

public boolean removePage(int pageNumber)

Remove the page from the document.

Parameters:

pageNumber - 0 based index to page number.

Returns:

true if the page was found false otherwise.

importPage

public PDPage importPage(PDPage page)
                  throws IOException

This will import and copy the contents from another location. Currently the content stream is stored in a scratch file. The scratch file is associated with the document. If you are adding a page to this document from another document and want to copy the contents to this document's scratch file then use this method otherwise just use the addPage method.

Parameters:

page - The page to import.

Returns:

The page that was imported.

Throws:

IOException - If there is an error copying the page.

getDocument

public COSDocument getDocument()

This will get the low level document.

Returns:

The document that this layer sits on top of.

getDocumentInformation

public PDDocumentInformation getDocumentInformation()

This will get the document info dictionary. This is guaranteed to not return null.

Returns:

The documents /Info dictionary

setDocumentInformation

public void setDocumentInformation(PDDocumentInformation info)

This will set the document information for this document.

Parameters:

info - The updated document information.

getDocumentCatalog

public PDDocumentCatalog getDocumentCatalog()

getNumberOfPages

public int getNumberOfPages()

Specified by:

getNumberOfPages in interface Pageable

This will send the PDF document to a printer. The printing functionality depends on the org.pdfbox.pdfviewer.PageDrawer functionality. The PageDrawer is a work in progress and some PDFs will print correctly and some will not. This is a convenience method to create the java.awt.print.PrinterJob. The PDDocument implements the java.awt.print.Pageable interface and PDPage implementes the java.awt.print.Printable interface, so advanced printing capabilities can be done by using those interfaces instead of this method.

Throws:

PrinterException - If there is an error while sending the PDF to the printer, or you do not have permissions to print this document.

public void silentPrint()
                 throws PrinterException

This will send the PDF to the default printer without prompting the user for any printer settings.

Throws:

PrinterException - If there is an error while printing.

print()

close

public void close()
           throws IOException

This will close the underlying COSDocument object.

Throws:

IOException - If there is an error releasing resources.

protect

public void protect(ProtectionPolicy pp)
             throws BadSecurityHandlerException

Protects the document with the protection policy pp. The document content will be really encrypted when it will be saved. This method only marks the document for encryption.

Parameters:

pp - The protection policy.

Throws:

BadSecurityHandlerException - If there is an error during protection.

See Also:

StandardProtectionPolicy, PublicKeyProtectionPolicy

openProtection

public void openProtection(DecryptionMaterial pm)
                    throws BadSecurityHandlerException,
                           IOException,

Tries to decrypt the document in memory using the provided decryption material.

Parameters:

pm - The decryption material (password or certificate).

Throws:

BadSecurityHandlerException - If there is an error during decryption.

IOException - If there is an error reading cryptographic information.

CryptographyException - If there is an error during decryption.

See Also:

StandardDecryptionMaterial, PublicKeyDecryptionMaterial

getCurrentAccessPermission

public AccessPermission getCurrentAccessPermission()

Returns the access permissions granted when the document was decrypted. If the document was not decrypted this method returns the access permission for a document owner (ie can do everything). The returned object is in read only mode so that permissions cannot be changed. Methods providing access to content should rely on this object to verify if the current user is allowed to proceed.

Returns:

the access permissions for the current user on the document.

getSecurityHandler

public SecurityHandler getSecurityHandler()

Get the security handler that is used for document encryption.

Returns:

The handler used to encrypt/decrypt the document.
