SetBkMode info  Overview  Group

The SetBkMode function sets the background mix mode of the specified device context. The background mix mode is used with text, hatched brushes, and pen styles that are not solid lines.

int SetBkMode(

    HDC hdc,

// handle of device context

    int iBkMode 

// flag specifying background mode



Identifies the device context.
Specifies the background mode. This parameter can be either of the following values:




Background is filled with the current background color before the text, hatched brush, or pen is drawn.


Background remains untouched.

Return Values

If the function succeeds, the return value specifies the previous background mode.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


The SetBkMode function affects the line styles for lines drawn using a pen created by the CreatePen function. SetBkMode does not affect lines drawn using a pen created by the ExtCreatePen function.

The iBkMode parameter can also be set to driver-specific values. GDI passes such values to the device driver and otherwise ignores them.
