This short topic describes how to remove watermark from PDF using Python. It encompasses all the resources required to establish the environment, a step-by-step procedure to develop the application, and a runnable sample code to remove watermark text from PDF using Python. You will also experience working with different types of artifacts on a page and filtering out the artifacts of the required types.

Steps to Delete Watermark from PDF using Python

1. Establish the environment to add Aspose.PDF for Python via .NET into your project to remove the watermark
2. Access the source PDF file using the Document class object to delete the watermark
3. Traverse through all the artifact on each page of the document and make a list of watermark-type artifacts
4. Delete all the watermarks, once the list is populated with the desired artifacts
5. Save the generated PDF file on the disk after removing the watermarks

The aforementioned steps explain the procedure to remove watermark from PDF document using Python by exposing the important resources, classes, methods, and properties required while developing this application. Initially, the source PDF file is loaded using the Document class object, and then all of its pages are traversed. For each page, respective artifacts are checked for the type watermark and saved inside a list for removal at the end of the traversal.

Code to Remove Watermark from PDF using Python

This code exhibits the procedure to develop a water mark remover in PDF using Python. It accesses the Page.artifacts collection to identify the watermark type artifacts by comparing the Subtype property with the enumerator value Artifact.artifact_subtype.WATERMARK. Once all the watermark artifacts are traversed and collected inside a list, this list is then parsed and respective watermarks are deleted from each page separately.
