Device Context Operations

An application can perform the following operations on a device context:

• Enumerate existing graphic objects.
• Select new graphic objects.
• Delete existing graphic objects.
• Save the current graphic objects, their attributes, and the graphic modes.
• Restore previously saved graphic objects, their attributes, and the graphic modes.

In addition, an application can use a device context to determine how graphics output is translated, cancel lengthy drawing operations (begun by a thread in a multithreaded application), or reset a printer to a particular state.
