Rich Graphics
Features
Sample
Description
ComponentOne PDF creates documents using commands that are similar to those provided by the .NET Graphics class, and the same objects (fonts, colors, rectangles, points, etc.). The main difference is that C1Pdf always uses points as units, while the .NET Graphics class uses pixels by default and allows you to switch to other coordinate systems with transforms. This demo requires Adobe Reader to view the PDF.
