Windows supports five graphic modes that allow an application to specify how colors are mixed, where output appears, how the output is scaled, and so on. These modes, which are stored in a DC, are described in the following table.
Graphics modeDescriptionBackgroundDefines how background colors are mixed with existing window or screen colors for bitmap and text operations.DrawingDefines how foreground colors are mixed with existing window or screen colors for pen, brush, bitmap, and text operations.MappingDefines how graphics output is mapped from logical (or world) space onto the window, screen, or printer paper.Polygon-fillDefines how the brush pattern is used to fill the interior of complex regions.StretchingDefines how bitmap colors are mixed with existing window or screen colors when the bitmap is compressed (or scaled down).
As it does with graphic objects, the system initializes a DC with default graphic modes. An application can retrieve and examine these default modes by calling the following
