FloodFill

The FloodFill function fills an area of the display surface with the current brush. The area is assumed to be bounded as specified by the crFill parameter.

Note  The FloodFill function is included only for compatibility with 16-bit versions of Windows. For Win32-based applications, use the ExtFloodFill function with FLOODFILLBORDER specified.

BOOL FloodFill(
  HDC hdc,          // handle to device context
  int nXStart,      // x-coordinate, where fill begins
  int nYStart,      // y-coordinate, where fill begins
  COLORREF crFill   // fill color
);
 

Parameters

hdc

Handle to a device context.

nXStart

Specifies the logical x-coordinate of the point where filling is to begin.

nYStart

Specifies the logical y-coordinate of the point where filling is to begin.

crFill

Specifies the color of the boundary or of the area to be filled.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Windows NT: To get extended error information, call GetLastError.

Remarks

Following are reasons this function might fail:

• The fill could not be completed.
• The given point has the boundary color specified by the crFill parameter.
• The given point lies outside the current clipping region — that is, it is not visible on the device.
