From within any .NET application (using C# or VB.NET), PDF Toolkit for .NET SDK allows .NET developers to modify any existing PDF document.
Powerful PDF Merger for .NET Environments
From within any .NET application (using C# or VB.NET), VeryPDF PDF Merger for .NET SDK allows .NET software developers the ability to take any existing PDF document and merge, stamp, append, form fill, flatten, encrypt, rotate, scale, split and so much more. Use an entire PDF document or just specific PDF pages. Add content to existing PDF pages or create new pages from scratch. Do all of this using an object model that is intuitive and easy to learn yet flexible enough to put the power into the hands of the developer.

Performance
Performance was a major consideration during the development of VeryPDF PDF Merger for .NET SDK. The techniques used to parse and manage the imported data are extremely fast and well designed. Only the data required in the output document is parsed and commonly used documents or pages can be stored as static variable to eliminate repeated parsing of the same data. This results in extremely fast performance.
Ease of Use
The VeryPDF PDF Merger for .NET SDK object model is intuitive and easy to learn.
Two documents can be merged together and output to a Web Form, file, byte array, or System.IO.Stream object with just two lines of code:
MergeDocument document = MergeDocument.Merge( @"C:\DocA.pdf", @"C:\DocB.pdf" );
document.Draw( @"C:\DocOut.pdf" );
Documents can be appended to an instantiated MergeDocument with one line of code:
document.Append( @"C:\DocC.pdf" );
A page (or range of pages) can be appended to an instantiated MergeDocument object with one line of code:
document.Append( @"C:\DocC.pdf", 2, 1 );
Flexibility
The VeryPDF PDF Merger for .NET SDK object model is very flexible and can be used to achieve many PDF manipulation tasks. The MergeDocument object can be used to merge and append PDF documents. Pages from the resulting document can then be accessed and new content can be added to the pages.
VeryPDF PDF Merger for .NET SDK also includes an ImportedPage object that can be used to add content to an imported page using the Generator for .NET object model. This object inherits from the Generator for .NET's Page object and can have Page Elements or Custom Page Elements added to it. This is ideal for form filling or using an existing PDF document as a template.
The included ImportedPageArea and ImportedPageData objects are Page Elements that allow an imported page to be placed on a Generator for .NET page and be scaled, shifted or rotated. This allows multiple pages from an existing PDF to be placed onto one page. This is ideal for pre-press work as well and using existing PDF documents as templates for portions of a page.
Objects and methods are also included for reading the content from an imported page and for determining the number of pages in an imported PDF document.
