Properties

AuthorizationOnDocumentOpen

Gets or sets a value indicating whether authorization should be handled right away when PDF document is opened or when the first string or stream is read.

Default value: false.

public bool AuthorizationOnDocumentOpen { get; set; }
Public Property AuthorizationOnDocumentOpen As Boolean
Property Value
System.Boolean

true if authorization should be handled right away when PDF document is opened; otherwise, false.

Gets the default options used for loading any PdfDocument from a PDF file.

public static PdfLoadOptions Default { get; }
Public Shared ReadOnly Property Default As PdfLoadOptions
Property Value
PdfLoadOptions

The default options used for loading any PdfDocument from a PDF file.

Password

Gets or sets the password used to load a PDF document from a password-encrypted PDF file.

If PDF file is not encrypted, then this property is ignored.

If PDF file is encrypted and Password is invalid, then InvalidPdfPasswordException is thrown when loading a PDF document.

public string Password { get; set; }
Public Property Password As String
Property Value
System.String

The password used to load a PDF document from a password-encrypted PDF file.

Exceptions
System.ArgumentNullException

Value is null.

ReadOnly

Gets or sets a value indicating whether to load a PdfDocument from a read-only PDF file so that changes made to the PdfDocument cannot be saved back to the same PDF file.

When a PDF file is opened in Adobe Acrobat Reader, it will lock the file so no other process can write to the file while it is opened. Use this property to load a PdfDocument from the PDF file in a read-only mode while it is still opened in Adobe Acrobat Reader.

Also, if you want to open a PDF file in Adobe Acrobat Reader while the PdfDocument is loaded from the PDF file and before it is closed, then use this property to load a PdfDocument from a PDF file in a read-only mode.

Note that loading a PdfDocument from a PDF file in a read-only mode (without acquiring an exclusive write lock on the file) might lead to unpredictable behavior if the file is simultaneously changed by another process because the PDF file is read into memory incrementally and lazily. To prevent the unpredictable behavior at the expense of performance, use Load() method to read the entire PDF file into memory.

Default value: false.

public bool ReadOnly { get; set; }
Public Property ReadOnly As Boolean
Property Value
System.Boolean

true to load PdfDocument from a read-only PDF file so that changes made to the PdfDocument cannot be saved back to the same PDF file; otherwise, false.

Events
