C1.Framework.Drawing.Gdi.DeviceContexts.DeviceContext.SetBackgroundMode
SetBackgroundMode Method
SetBackgroundMode(BackgroundMode)
Sets the background mode of the device context.
Declaration
public BackgroundMode SetBackgroundMode(BackgroundMode backgroundMode)Parameters
| Type | Name | Description |
|---|---|---|
| BackgroundMode | backgroundMode |
Returns
| Type | Description |
|---|---|
| BackgroundMode | Returns the previous foreground mode of the device context. |
Remarks
The BackgroundMode affects the line styles for lines drawn using a pen created by the CreatePen GDI API function. The BackgroundMode does not affect lines drawn using a pen created by the ExtCreatePen GDI API function.
backgroundMode parameter can also be set to driver-specific values.
GDI passes such values to the device driver and otherwise ignores them.
