How to insert Image Stamp to PDF document pages via Java SDK

In order to add Image Stamp to PDF via Cloud Java SDK, we’ll use Aspose.PDF Cloud Java SDK This Cloud SDK allows you to easily build cloud-based PDF creator, editor & add link apps in Java language for various cloud platforms. Open Repository package manager, search for Aspose.PDF Cloud and install. You may also use the following command from the Package Manager Console for install it using Maven.

Add Aspose Cloud repository to your application pom.xml

Add Aspose Cloud repository


    <repositories>
        <repository>
            <id>aspose-cloud</id>
            <name>Aspose Cloud Repository</name>
            <url>https://releases.aspose.cloud/java/repo/</url>
        </repository>
    </repositories>

To install the API client library to your local Maven repository, simply execute:

Installation from Github


    mvn clean install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

Deploy Maven repository


    mvn clean deploy

Steps to add Stamps via Cloud Java

Aspose.PDF Cloud developers can easily add Image Stamp to PDF in just a few lines of code.

  1. Create an object to connect to the Pdf.Cloud API
  2. Upload your document file
  3. Create a new Image stamp for page with the required properties
  4. Append new Image stamp to the document page using putPageAddStamp() function
  5. Perform some action after successful addition
  6. Download the result if needed it

Work with the Stamps via Java SDK

Adding stamps to PDF documents serves multiple purposes, enhancing both the functionality and security of digital files. As a developer, understanding these benefits can inform the implementation of features that streamline document workflows and reinforce data integrity.​ In collaborative environments, documents often require multiple reviews and approvals. Stamps can deter unauthorized distribution and modification. Stamping functionality into PDF management systems can significantly enhance document workflows, security, and compliance. By effectively leveraging stamps, organizations can ensure their documents are professional and protected. Add the Stamps to PDF documents with Aspose.PDF Cloud Java SDK.

  • Add PDF document’s header & footer in text or image format.
  • Add tables & stamps (text or image) to PDF documents.
  • Append multiple PDF documents to an existing file.
  • Work with PDF attachments, annotations, & form fields.
  • Apply encryption or decryption to PDF documents & set a password.
  • Delete all stamps & tables from a page or entire PDF document.
  • Delete a specific stamp or table from the PDF document by its ID.
  • Replace single or multiple instances of text on a PDF page or from the entire document.
  • Extensive support for converting PDF documents to various other file formats.
  • Extract various elements of PDF files & make PDF documents optimized.
  • You can try out our free Apps to test the functionality online.
