PdfPermissions enumeration
PdfPermissions enumeration
Specifies the operations that are allowed to a user on an encrypted PDF document.
Members
| Name | Description |
|---|---|
| DISALLOW_ALL | Disallows all operations on the PDF document. This is the default value. |
| ALLOW_ALL | Allows all operations on the PDF document. |
| CONTENT_COPY | Copy or otherwise extract text and graphics from the document by operations other than that controlled by PdfPermissions.CONTENT_COPY_FOR_ACCESSIBILITY. |
| CONTENT_COPY_FOR_ACCESSIBILITY | Extract text and graphics (in support of accessibility to users with disabilities or for other purposes). |
| MODIFY_CONTENTS | Modify the contents of the document by operations other than those controlled by PdfPermissions.MODIFY_ANNOTATIONS, PdfPermissions.FILL_IN, and PdfPermissions.DOCUMENT_ASSEMBLY. |
| MODIFY_ANNOTATIONS | Add or modify text annotations, fill in interactive form fields, and, if PdfPermissions.MODIFY_CONTENTS is also set, create or modify interactive form fields (including signature fields). |
| FILL_IN | Fill in existing interactive form fields (including signature fields), even if PdfPermissions.MODIFY_CONTENTS is clear. |
| DOCUMENT_ASSEMBLY | Assemble the document (insert, rotate, or delete pages and create document outline items or thumbnail images), even if PdfPermissions.MODIFY_CONTENTS is clear. |
| PRINTING | Print the document (possibly not at the highest quality level, depending on whether PdfPermissions.HIGH_RESOLUTION_PRINTING is also set). |
| HIGH_RESOLUTION_PRINTING | 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 PdfPermissions.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.
doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
builder.writeln('Hello world!')
# Extend permissions to allow the editing of annotations.
encryption_details = aw.saving.PdfEncryptionDetails(user_password='password', owner_password='', permissions=aw.saving.PdfPermissions.MODIFY_ANNOTATIONS | aw.saving.PdfPermissions.DOCUMENT_ASSEMBLY)
# Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
# to modify how that method converts the document to .PDF.
save_options = aw.saving.PdfSaveOptions()
# Enable encryption via the "EncryptionDetails" property.
save_options.encryption_details = encryption_details
# When we open this document, we will need to provide the password before accessing its contents.
doc.save(file_name=ARTIFACTS_DIR + 'PdfSaveOptions.EncryptionPermissions.pdf', save_options=save_options)
