Math2DFloodFill_4Neighbour(Int32, Int32, FuncInt32, Int32, Boolean, ActionInt32, Int32, Int32, Int32, Int32, Int32) Method

public static void FloodFill_4Neighbour(
	int xStart,
	int yStart,
	Func<int, int, bool> IsPixelToBeFilled,
	Action<int, int> SetPixelToNewValue,
	int xLower,
	int yLower,
	int xSize,
	int ySize
)

Parameters

xStart  Int32

The start pixel's x coordinate.

yStart  Int32

The start pixel's x coordinate.

IsPixelToBeFilled  FuncInt32, Int32, Boolean

Function that evaluated if the pixel fulfills a condition so that it should be set to a new value. Args are the x and y pixel coordinates, the return value is true if the pixel should be set to a new value.

SetPixelToNewValue  ActionInt32, Int32

Action to set the pixel to a new value. Args are the x and y coordinates of the pixel. Since the pixel's value is never tested again, there is no need to really set the pixel's value. Thus, this action can also be used to count the pixels that fulfill the condition given in IsPixelToBeFilled, etc.

xLower  Int32

The lowest possible value for a pixel's x coordinate.

yLower  Int32

The lowest possible value for a pixel's y coordinate

xSize  Int32

The x size. The x coordinate can take values from xStart to xStart+xSize-1.

ySize  Int32

The y size. The y coordinate can take values from yStart to yStart+ySize-1.
