## Device context information and manipulation

The following functions provide the API routines that are used to change the attributes of the currently active device context, such as the current foreground and background colors, and the current pen pattern. These routines also provide information about device contexts, such as the resolution, pixel depth, aspect ratio etc.

Note that some of these functions are bound to a specific device context, and if this device context is not the currently active context, the active context will not be affected.
