Constructor Detail

Line

public Line(int ox1,
            int oy1,
            int ox2,
            int oy2)

Creates a new straight line selection using the specified starting and ending offscreen integer coordinates.

Line

public Line(double ox1,
            double oy1,
            double ox2,
            double oy2)

Creates a new straight line selection using the specified starting and ending offscreen double coordinates.

Line

public Line(int sx,
            int sy,
            ImagePlus imp)

Starts the process of creating a new user-generated straight line selection. 'sx' and 'sy' are screen coordinates that specify the start of the line. The user will determine the end of the line interactively using rubber banding.
