Enum PdfPermissions

Enum PdfPermissions

Namespace: Aspose.Words.Saving
Assembly: Aspose.Words.dll (26.2.0)

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

[Flags]
public enum PdfPermissions

Fields

AllowAll = 65535

Allows all operations on the PDF document.

ContentCopy = 16

Copy or otherwise extract text and graphics from the document by operations other than that controlled by Aspose.Words.Saving.PdfPermissions.ContentCopyForAccessibility.

ContentCopyForAccessibility = 512

Extract text and graphics (in support of accessibility to users with disabilities or for other purposes).

DisallowAll = 0

Disallows all operations on the PDF document. This is the default value.

DocumentAssembly = 1024

Assemble the document (insert, rotate, or delete pages and create document outline items or thumbnail images), even if Aspose.Words.Saving.PdfPermissions.ModifyContents is clear.

FillIn = 256

Fill in existing interactive form fields (including signature fields), even if Aspose.Words.Saving.PdfPermissions.ModifyContents is clear.

HighResolutionPrinting = 2052

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 Aspose.Words.Saving.PdfPermissions.Printing is set), printing shall be limited to a low-level representation of the appearance, possibly of degraded quality.

ModifyAnnotations = 32

Add or modify text annotations, fill in interactive form fields, and, if Aspose.Words.Saving.PdfPermissions.ModifyContents is also set, create or modify interactive form fields (including signature fields).

ModifyContents = 8

Modify the contents of the document by operations other than those controlled by Aspose.Words.Saving.PdfPermissions.ModifyAnnotations, Aspose.Words.Saving.PdfPermissions.FillIn, and Aspose.Words.Saving.PdfPermissions.DocumentAssembly.

Printing = 4

Print the document (possibly not at the highest quality level, depending on whether Aspose.Words.Saving.PdfPermissions.HighResolutionPrinting is also set).

Examples

Shows how to set permissions on a saved PDF document.

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

                                                                builder.Writeln("Hello world!");

                                                                // Extend permissions to allow the editing of annotations.
                                                                PdfEncryptionDetails encryptionDetails =
                                                                    new PdfEncryptionDetails("password", string.Empty, 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);
