FileAccess

public FileAccess(ExternalHandlers externalHandlers,
                  PdfResources res,
                  DecoderOptions options)

Method Detail

isFileViewable

public boolean isFileViewable(PdfObjectReader currentPdfFile)

getRes

public PdfResources getRes()

openPdfFileFromStream

public final void openPdfFileFromStream(Object filename,
                                        String password)
                                 throws PdfException

routine to open PDF file and extract key info from pdf file so we can decode any pages which also sets password. Does not actually decode the pages themselves. Also reads the form data. You must explicitly close your stream!!

Throws:

PdfException

setPageNumber

public void setPageNumber(int newPage)

getPageCount

public int getPageCount()

get page count of current PDF file

isPasswordSupplied

public boolean isPasswordSupplied(PdfObjectReader currentPdfFile)

getObjectStore

public ObjectStore getObjectStore()

return object which provides access to file images and name

setUserEncryption

public void setUserEncryption(Certificate certificate,
                              PrivateKey key)

getNewReader

public PdfObjectReader getNewReader()

isOpen

public boolean isOpen()

getIO

public PdfObjectReader getIO()

setIO

public void setIO(PdfObjectReader pdfObjectReader)

isEncrypted

public final boolean isEncrypted()

return true if the current pdf file is encrypted
check isFileViewable(),

if file is encrypted and not viewable - a user specified password is needed.

dispose

public void dispose()

getFilename

public String getFilename()

readAllPageReferences

public int readAllPageReferences(boolean ignoreRecursion,
                                 PdfObject pdfObject,
                                 Map<String,Integer> rotations,
                                 Map<String,String> parents,
                                 int tempPageCount,
                                 AcroRenderer formRenderer,
                                 PdfResources res,
                                 int insetW,
                                 int insetH)

read the data from pages lists and pages so we can open each page.
