Change Grid Values - Flood Fill

Author: O.Conrad (c) 2018
Menu: Grid | Values

Description

A flood fill algorithm will be used for replacement of grid cell values starting at the positions of the input points. If one or more points are selected, only these will be processed, otherwise all. If the target grid is not set, the changes will be applied to the original grid.

Parameters

	Value to be replaced	choice	`REPLACE`	-	Available Choices: [0] value at mouse position [1] fixed value Default: 0
	Fixed value to be replaced	floating point number	`REPLACE_VALUE`	Replace only this value with respect to the specified tolerance.	Default: 0.000000
	Tolerance	floating point number	`TOLERANCE`	-	Minimum: 0.000000 Default: 1.000000
	Ignore No-Data	boolean	`IGNORE_NODATA`	Do not fill areas representing no-data.	Default: 1
