Virtual Buffers

By now, it should be apparent that virtual buffers are the graphics cornerstone in Fastgraph for Windows programs. When we originally introduced virtual buffers, we talked about how to create virtual buffers and display or "blit" their contents in the window's client area. In this section, we'll begin with a review of these tasks and the associated Fastgraph functions. We'll then introduce other Fastgraph functions for working with virtual buffers, including copying data between virtual buffers, printing, communicating with the Windows clipboard, and some miscellaneous virtual buffer support functions. We'll wrap up the section with two example programs that show how to pan and scroll with virtual buffers.
