Welcome to the PDF Stamper SDK. This SDK allows you to stamp barcodes, hyperlinks, images, lines and text to PDF pages.

PDF Stamper SDK is a professional PDF stamp creator or PDF watermark creator, which can help you stamp PDF with images, text, graphic lines and rectangles. With the help of this stamp creator, you can annotate your PDF with custom stamps.

PDF Stamper SDK is a powerful and useful tool which enables you to easily apply company logos, signatures, charts, page numbers, date and time, contact information to the PDF files.

You can use PDF Stamper SDK to add new contents to existing PDF documents. The PDF Stamper component contains a PHP module which allow PHP developers to add new content to existing PDF documents in a fast, easy, and reliable way.

The PHP component in PDF Stamper SDK comes with all features of the PDF Stamper component, including support for encrypted PDF files if rights are granted or an owner password is known.

PDF Stamper SDK is a standalone SDK DLL Library, it doesn't require Adobe Acrobat or Adobe Reader, it enables you to add sets of stamps to large PDF document collections. Insert text, dynamic text, bates numbering, watermarks, headers and footers to your PDFs with advanced control.

PDF Stamper SDK also allows you to undo stamps; sequence and combine stamping tasks with other tasks in batch mode; and apply navigation, form field and JavaScript-related actions.

PDF Stamper SDK comes with an extensive range of predefined stamp sets that help you get started and help you get the job done quicker. PDF Stamper SDK is a software component intended to be used by C++, VB, Delphi, PHP, C#, VB.NET, ASP, PHP, etc. developers, and it enables you to integrate PDF stamping functions into your applications.

With the help of this development kit, you can build programs that have the ability to apply watermarks consisting of images, text or graphic lines, making it possible to personalize documents or prevent them from being stolen. Of course, the complexity of the created application depends on the type of project you have in mind, but PDF Stamper SDK enables you to integrate several useful customization options and supports multiple image formats. For instance, it is possible to customize the position and appearance of the watermarks, process only specific page ranges and insert various dynamic elements, such as the current date or time, page numbers, file names and so on.

When applying image-based watermarks, multiple popular picture formats are supported, including JPEG, GIF, TIF, TIFF, PNG and BMP.

The downloadable package includes libraries for multiple programming languages, including C#, C++, Visual Basic and VB.NET. Because of this, the development kit can help you create applications for a wide range of platforms.

Also provided are sample programs that allow you to test the capabilities of the component and get a good idea of what can be achieved with its help. Naturally, they are not particularly complex, but they are merely designed to demonstrate the capabilities of the included libraries.

Developers can consult the bundled user manual to ensure they get started on the right track. It explains how the component can be integrated into your application and lists all the supported parameters.
