Constructor Detail

Arrow

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

Arrow

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

Method Detail

draw

public void draw(Graphics g)

Draws this arrow on the image.

Overrides:

draw in class Line

getMask

public ImageProcessor getMask()

Description copied from class: Roi

Always returns null for rectangular Roi's

Overrides:

getMask in class Roi

drawPixels

public void drawPixels(ImageProcessor ip)

Description copied from class: Line

If the width of this line is less than or equal to one, draws the line. Otherwise draws the outline of the area of this line

Overrides:

drawPixels in class Line

See Also:

ImageProcessor.setColor(java.awt.Color), ImageProcessor.setLineWidth(int)

contains

public boolean contains(int x,
                        int y)

Description copied from class: Roi

Returns whether the center of pixel (x,y) is contained in the Roi. The position of a pixel center determines whether a pixel is selected. Points exactly at the left (right) border are considered outside (inside); points exactly on horizontal borders are considered outside (inside) at the border with the lower (higher) y. This convention is opposite to that of the java.awt.Shape class.

Overrides:

contains in class Line

getBounds

public Rectangle getBounds()

Return the bounding rectangle of this arrow.

Overrides:

getBounds in class Line

handleMouseDown

protected void handleMouseDown(int sx,
                               int sy)

Overrides:

handleMouseDown in class Line

clipRectMargin

protected int clipRectMargin()

Overrides:

clipRectMargin in class Line

isDrawingTool

public boolean isDrawingTool()

Description copied from class: Roi

Returns 'true' if this is an ROI primarily used from drawing (e.g., TextRoi or Arrow).

Overrides:

isDrawingTool in class Roi
