Identifies a device context.
Specifies the logical x-coordinate of the point where filling is to begin.
Specifies the logical y-coordinate of the point where filling is to begin.
Specifies the color of the boundary or of the area to be filled. The
interpretation of crColor
depends on the value of the fuFillType
Specifies the type of fill operation to be performed. It must be one of the
||The fill area is bounded by the color specified by the crColor parameter. This style is identical to the filling performed by the FloodFill function.
||The fill area is defined by the color that is specified by crColor. Filling continues outward in all directions as long as the color is
encountered. This style is useful for filling areas with multicolored boundaries.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError
Following are some of the reasons this function might fail:
- The filling could not be completed.
- The specified point has the boundary color specified by the crColor parameter (if FLOODFILLBORDER was requested).
- The specified point does not have the color specified by crColor (if FLOODFILLSURFACE was requested).
- The point is outside the clipping region that is, it is not visible on the device.
If the fuFillType
parameter is FLOODFILLBORDER, Windows assumes that the area to be filled is
completely bounded by the color specified by the crColor
parameter. The function begins filling at the point specified by the nXStart
parameters and continues in all directions until it reaches the boundary.
is FLOODFILLSURFACE, Windows assumes that the area to be filled is a single
color. The function begins to fill the area at the point specified by nXStart
and continues in all directions, filling all adjacent regions containing the
color specified by crColor
Only memory device contexts and devices that support raster-display operations
support the ExtFloodFill
function. To determine whether a device supports this technology, use the GetDeviceCaps
