FloodSpiller-CSharp — an open-source multi-purpose flood-filling algorithm for C#

What can you do with it?

  • run a flood-fill in two-dimensional space
  • pass your own conditions for visiting positions and for stopping the flood
  • pass your own callbacks that will be executed for visited positions
  • use LIFO, FIFO or priority queue for deciding in what order positions should be processed
  • use scanline fill to double up execution speed
  • reuse position queue and the matrix used for marking visited positions to minimize memory allocation

It is:

  • fast
  • easy to use
  • elastic
  • compatible with .NET Standard 2.0 and .NET Framework 3.5

Code sample

private int[,] _positionMarkMatrix;

public void BucketFillImage(int floodStartX, int floodStartY, Color replacedColor, Color targetColor)
	var floodParameters = new FloodParameters(floodStartX, floodStartY)
		BoundsRestriction = new FloodBounds(_imageSizeX, _imageSizeY),
		NeighbourhoodType = NeighbourhoodType.Four,
		Qualifier = (x, y) => GetColor(x, y) == replacedColor,
		NeighbourProcessor = (x, y, mark) => SetColor(x, y, targetColor),
		ProcessStartAsFirstNeighbour = true

	var floodSpiller = new FloodSpiller();
	floodSpiller.SpillFlood(floodParameters, _positionMarkMatrix);
