A sample PDF created in C# with Quick PDF Library.

Quick PDF Library (formerly iSEDQuickPDF) is a royalty-free PDF developer SDK used in thousands of desktop and server applications for working with PDFs on all levels. Its robust API includes over 500 functions, enabling you to create, render, print split, merge, encrypt, modify and manipulate PDF form fields. Quick PDF Library provides advanced support for JavaScript. Images can be added in BMP, TIFF, JPEG, PNG and EMF format with Quick PDF Library. Quick PDF Library allows you to embed TrueType and Type1 fonts. With Quick PDF Library, TrueType fonts can be subsetted allowing Unicode text to be drawn. It also includes a full built-in PDF rasterizer allowing PDFs to be rendered to the screen or printer. Adding advanced PDF functionality to your applications is simple with Quick PDF Library (formerly iSEDQuickPDF).
