This short tutorial guides on how to remove restrictions on PDF document in Python. It has all the details for establishing the development environment, a list of steps to be performed while writing the application, and a runnable sample code to remove all restrictions from PDF in Python. After removing all the restrictions, it will teach you to apply a few restrictions if required.
Steps to Unlock PDF Restrictions in Python
- Set the environment to use Aspose.PDF for Python via .NET to remove restrictions
- Create a DocumentPrivilege class object and initialize it with DocumentPrivilege.allow_all
- Create a PdfFileSecurity object for allowing the desired privileges
- Bind the target PDF having some restrictions on it using the PdfFileSecurity object
- Call the set_privilege() method to apply the settings
- Save the resultant PDF file after removing all the restrictions
These steps define the process to develop a PDF file restriction remover in Python. In this process, a DocumentPrivilege object is declared and initialized with an “Allow All” value by default followed by declaring a PdfFileSecurity class object to open or bind the target PDF file. In the final steps, call the set_privilege() method by passing the DocumentPrivilege class object as an argument and save the resultant PDF file where all the restrictions are removed.
Code to Remove Restrictions on PDF Document in Python
The aforementioned code demonstrates the process to develop a PDF restriction remover software in Python. In this sample code, we have used the DocumentPrivilege class for setting the allow_all privilege however you may use other values also for instance allow_fill_in, modify_contents, and modify_annotations to list a few. Using the PDFFileSecurity class, you may enable/disable different restrictions like allow_print, allow_copy, and forbid_all to apply all the restrictions.
