Interpolate Values Along Line

Description
The tool allows one to change the values of the input grid along a line. The values along the line will be interpolated linearly between the start and the end point of the line. Thus you must assure that these grid cells contain valid data. Optionally the changes can be limited to grid cells with No Data only.
Once the tool is executed and running, you can use the 'Action' tool to digitize a line. Use left mouse button clicks to set line vertices. A right mouse button click will finish the line.
