## Detailed Description

A PDF document object can be constructed with an existing PDF file from file path, memory buffer, a custom implemented FileReaderCallback object and an input file stream. And then call function PDFDoc.Load or PDFDoc.StartLoad to load document content. This class offers functions to retrieve different part of a PDF document. For example:

- To retrieve pages, please use functions PDFDoc.GetPageCount and PDFDoc.GetPage.
- To retrieve bookmark, such as function PDFDoc.GetRootBookmark, PDFDoc.CreateRootBookmark, etc.
- To retrieve some document's dictionaries (in low-level), such as functions PDFDoc.GetCatalog, PDFDoc.GetTrailer, etc.
- To retrieve reading bookmark, such as functions PDFDoc.GetReadingBookmarkCount, PDFDoc.GetReadingBookmark, etc.
- To check if a PDF document has interactive form, please use function PDFDoc.HasForm.
- To check if a PDF document has header-footer, please use function PDFDoc.HasHeaderFooter. To modify header-footer, please refer to functions such as PDFDoc.AddHeaderFooter, PDFDoc.UpdateHeaderFooter, and PDFDoc.RemoveAllHeaderFooters.

This class also offers functions for features, such as saving current document as another PDF file, importing pages from another PDF file, setting security handler in order to save encrypted PDF file, and so on.
This class object can also be used to construct objects of other classes in order to access specified information in PDF document:

- To access form, please construct a Form object with PDF document object.
- To access additional actions, please construct an AdditionalAction object with PDF document object.
- To access viewer preferences information, please construct a DocViewerPrefs object with PDF document object.
- To access metadata information, please construct a Metadata object with PDF document object.
- To manage page labels information, please construct a PageLabels object with PDF document object.
- To search among a PDF file, please construct a TextSearch object with PDF document object.
- To access layers, please construct a LayerTree object with PDF document object. And to render layers, please constructor a LayerContext object with PDF document object.
- To construct a new FileSpec object.
- To manage associated files, please construct an AssociatedFiles object with PDF document object.
- To access name tree, please construct a PDFNameTree object with PDF document object. Specially, for EmbeddedFiles name tree, an Attachments object can be constructed with PDF document object, for convenient use.
- To do redaction, please construct a Redaction object with PDF document object.

## Member Function Documentation

## ◆ AddHeaderFooter()

PDFDoc.AddHeaderFooter | ( | headerfooter |  | ) |

Add new header-footer.

A PDF document can be added header-footer sereral times. When a new header-footer is added, the old ones will not be removed but be covered by the new one if the old ones appear in the same place as new one.

Parameters

  [in] | headerfooter | A valid header-footer object to be added to current document.

Returns
  None.

## ◆ AddIndirectObject()

PDFDoc.AddIndirectObject | ( | pdf_object |  | ) |

Add a PDF object to current PDF document, to be an indirect object.

- If input PDF object is a direct object (whose indirect object number is 0), this functions will change it to be an indirect object and add to PDF document. Then return the new indirect object number.
- If input PDF object is already an indirect object (whose indirect object number is above 0), this function will not add it into document again. The return value will be its own indirect object number.

Parameters

  [in] | pdf_object | A PDFObject object. It should not be null.

Returns
  The new indirect object number. It would be above 0.

## ◆ AddPageFromTemplate()

PDFDoc.AddPageFromTemplate | ( | template_name |  | ) |

Adds a new PDF page to document, from a named template.

There may exist hidden pages in a PDF document. Hidden pages are mapped to the names defined in the template name tree in the PDF document. This function can be used to add a hidden page to the end of the PDF document.
Class PDFNameTree (initialized with type PDFNameTree.e_Templates) can be used to determine which template names are available.
After a template has been added, the name will be moved to the document's pages name tree internally.

Parameters

  [in] | template_name | The name of a template, whose mapping hidden page will be added to the end of current PDF document. If the template name cannot be found, exception e_ErrParam will be thrown.

Returns
  A new PDF page object if input template name was found.

Parameters

  [in] | page_range | A range object that specifies some pages. These pages will be added a signature. The valid page range: from 1 to count. count is returned by function PDFDoc.GetPageCount.

This function does not support a range with a single index or a document with a single page.
  [in] | width | The width of paging seal. The value will be used for setting rectangle of the signature on each page.

For each element in input array, valid range: from 1 to (depth). depth is returned by function PDFDoc.GetBookmarkLevelDepth. If input array is an empty array, that means all bookmarks are used to generate "Table of Contents".

Returns
  None.

## ◆ CheckPassword()
