Detailed Description

Instead of drawing directly on a device (like the screen or a printer), you can use GDI classes to draw on a bitmap using a device context (DC). A device context is a structure that contains information about the drawing attributes (pens, brushes, text color, and so on) of a particular device. DC classes support a variety of device context operations.

• TDC is the root class for GDI DC wrapper classes.
• TWindowDC and its derived classes such as TClientDC and TScreenDC provide access to the area owned by a window.
• TCreatedDC and its derived classes provide access to various DCs that are created and deleted such as memory and print DCs.
