PdfPermissions enumeration

Specifies the operations that are allowed to a user on an encrypted PDF document.

[Flags]
public enum PdfPermissions

Values

Name Value Description
DisallowAll 0 Disallows all operations on the PDF document. This is the default value.
AllowAll FFFF Allows all operations on the PDF document.
ContentCopy 10 Copy or otherwise extract text and graphics from the document by operations other than that controlled by ContentCopyForAccessibility.
ContentCopyForAccessibility 200 Extract text and graphics (in support of accessibility to users with disabilities or for other purposes).
ModifyContents 8 Modify the contents of the document by operations other than those controlled by ModifyAnnotations, FillIn, and DocumentAssembly.
ModifyAnnotations 20 Add or modify text annotations, fill in interactive form fields, and, if ModifyContents is also set, create or modify interactive form fields (including signature fields).
FillIn 100 Fill in existing interactive form fields (including signature fields), even if ModifyContents is clear.
DocumentAssembly 400 Assemble the document (insert, rotate, or delete pages and create document outline items or thumbnail images), even if ModifyContents is clear.
Printing 4 Print the document (possibly not at the highest quality level, depending on whether HighResolutionPrinting is also set).
HighResolutionPrinting 804 Print the document to a representation from which a faithful digital copy of the PDF content could be generated, based on an implementation-dependent algorithm. When this flag is clear (and Printing is set), printing shall be limited to a low-level representation of the appearance, possibly of degraded quality.

Examples

Shows how to set permissions on a saved PDF document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Writeln("Hello world!");

PdfEncryptionDetails encryptionDetails =
    new PdfEncryptionDetails("password", string.Empty);

// Start by disallowing all permissions.
encryptionDetails.Permissions = PdfPermissions.DisallowAll;

// Extend permissions to allow the editing of annotations.
encryptionDetails.Permissions = PdfPermissions.ModifyAnnotations | PdfPermissions.DocumentAssembly;

// Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
// to modify how that method converts the document to .PDF.
PdfSaveOptions saveOptions = new PdfSaveOptions();

// Enable encryption via the "EncryptionDetails" property.
saveOptions.EncryptionDetails = encryptionDetails;

// When we open this document, we will need to provide the password before accessing its contents.
doc.Save(ArtifactsDir + "PdfSaveOptions.EncryptionPermissions.pdf", saveOptions);
