MatFloodFill Method (Point, Scalar, Rect, NullableScalar, NullableScalar, FloodFillFlag) OpenCvSharp Class Library
Fills a connected component with the given color. Input/output 1- or 3-channel, 8-bit, or floating-point image. It is modified by the function unless the FLOODFILL_MASK_ONLY flag is set in the second variant of the function. See the details below.

Namespace:  OpenCvSharp.CPlusPlus
Assembly:  OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax

public int FloodFill(
	Point seedPoint,
	Scalar newVal,
	out Rect rect,
	Nullable<Scalar> loDiff = null,
	Nullable<Scalar> upDiff = null,
	FloodFillFlag flags = FloodFillFlag.Link4
)

Parameters

seedPoint
Type: OpenCvSharp.CPlusPlusPoint
Starting point.
newVal
Type: OpenCvSharp.CPlusPlusScalar
New value of the repainted domain pixels.
rect
Type: OpenCvSharp.CPlusPlusRect
Optional output parameter set by the function to the minimum bounding rectangle of the repainted domain.
loDiff (Optional)
Type: SystemNullableScalar
Maximal lower brightness/color difference between the currently observed pixel and one of its neighbors belonging to the component, or a seed pixel being added to the component.
upDiff (Optional)
Type: SystemNullableScalar
Maximal upper brightness/color difference between the currently observed pixel and one of its neighbors belonging to the component, or a seed pixel being added to the component.
flags (Optional)
Type: OpenCvSharpFloodFillFlag
Operation flags. Lower bits contain a connectivity value, 4 (default) or 8, used within the function. Connectivity determines which neighbors of a pixel are considered.

Return Value

Type: Int32
