CDC::FloodFill 

  • Article

BOOLFloodFill(intx**,inty,COLORREFcrColor);**

Return Value

Nonzero if the function is successful; otherwise 0 is returned if the filling could not be completed, the given point has the boundary color specified by crColor, or the point is outside the clipping region.

Parameters

x

Specifies the logical x-coordinate of the point where filling begins.

y

Specifies the logical y-coordinate of the point where filling begins.

crColor

Specifies the color of the boundary.

Remarks

Fills an area of the display surface with the current brush. The area is assumed to be bounded as specified by crColor. The FloodFill function begins at the point specified by x and y and continues in all directions to the color boundary.

Only memory-device contexts and devices that support raster-display technology support the FloodFill member function. For information about RC_BITBLT capability, see the GetDeviceCaps member function.

The ExtFloodFill function provides similar capability but greater flexibility.
