Graphics Objects Overview

ObjectWindows encapsulates the Windows Graphics Device Interface (GDI) and makes it easier to use GDI graphics objects and functions by simplifying how you create and manipulate GDI objects.

From simple objects such as pens and brushes to more complex objects such as fonts and bitmaps, the GDI encapsulation of the ObjectWindows library provides a simple, consistent model for graphical programming in Windows.
