How to insert strikeout annotations to PDF documents via Aspose.PDF Cloud Python SDK

To add annotations into PDF, we’ll use Aspose.PDF Cloud Python SDK. This Cloud SDK assists Python programmers in developing cloud-based PDF creator, annotator, editor, and converter apps using Python programming language via Aspose.PDF REST API. Simply create an account at Aspose for Cloud and get your application information. Once you have the App SID & key, you are ready to give the Aspose.PDF Cloud Python SDK. If the python package is hosted on Github, you can install directly from Github:

Installation from Github


     
    pip install git+https://github.com/aspose-pdf-cloud/aspose-pdf-cloud-python.git

Package Manager Console Command

     
    pip install asposepdfcloud

Steps to add Strikeout annotations to PDF via Python

Aspose.PDF Cloud developers can easily load & add annotations to PDF in just a few lines of code.

  1. Install Python SDK.
  2. Uploads the input PDF.
  3. Creates a new StrikeOutAnnotation with properties like position, color, and text.
  4. Post Annotation to PDF.
  5. Validates the response.
  6. Download Annotated Document.
