Constructor Detail

pointHandler

protected pointHandler(ij.ImagePlus imp,
                       pointToolbar tb)

This constructor stores a local copy of its parameters and initializes the current spectrum. It also creates the object that takes care of the interactive work.

Parameters:

imp - ImagePlus object where points are being picked.

tb - pointToolbar object that handles the toolbar.

Method Detail

draw

public void draw(java.awt.Graphics g)

Draw the landmarks and outline the current point if there is one.

Overrides:

draw in class ij.gui.PolygonRoi

Parameters:

g - Graphics environment.

addPoint

protected void addPoint(int x,
                        int y)

This method adds a new point to the list, with a color that is as different as possible from all those that are already in use. The points are stored in pixel units rather than canvas units to cope for different zooming factors.

Parameters:

x - Horizontal coordinate, in canvas units.

y - Vertical coordinate, in canvas units.

addPoint

protected void addPoint(int x,
                        int y,
                        int color)

This method adds a new point to the list, with a specific color. The points are stored in pixel units rather than canvas units to cope for different zooming factors.

Parameters:

x - Horizontal coordinate, in canvas units.

y - Vertical coordinate, in canvas units.

color - Specific color.

findClosest

protected void findClosest(int x,
                           int y)

Let the point that is closest to the given coordinates become the current landmark.

Parameters:

x - Horizontal coordinate, in canvas units.

y - Vertical coordinate, in canvas units.

getColors

protected java.util.Vector<java.lang.Integer> getColors()

Return the list of colors.

getCurrentColor

protected java.lang.Integer getCurrentColor()

Return the color of the current object. Return -1 if there is none.

getIDs

protected java.util.Vector<java.lang.Integer> getIDs()

Return the list of IDs.

getPoint

protected java.awt.Point getPoint()

Return the current point as a Point object.

getPoints

protected java.util.Vector<java.awt.Point> getPoints()

Return the list of points.

isUsedColor

protected boolean isUsedColor(int color)

Return true if color is free. Return false if color is in use.

movePoint

protected void movePoint(int x,
                         int y)

Modify the location of the current point. Clip the admissible range to the image size.

Parameters:

x - Desired new horizontal coordinate in canvas units.

y - Desired new vertical coordinate in canvas units.

movePoint

protected void movePoint(int x,
                         int y,
                         java.lang.Integer color)

Modify the location of the current point. Clip the admissible range to the image size.

Parameters:

x - Desired new horizontal coordinate in canvas units.

y - Desired new vertical coordinate in canvas units.

color - Color index of the point to move.

removePoint

protected void removePoint()

Remove the current point. Make its color available again.

removePoint

protected void removePoint(java.lang.Integer color)

Remove a point of a given index. Make its color available again.

Parameters:

color - Color index of the point to remove.

removePoints

protected void removePoints()

Remove all points and make every color available.

setPointAction

protected void setPointAction(pointAction pa)

Stores a local copy of its parameter and allows the graphical operations to proceed. The present class is now fully initialized.

Parameters:

pa - pointAction object.

setSpectrum

protected void setSpectrum(int colorization)

Setup the color scheme.

Parameters:

colorization - Colorization code. Admissible values are {RAINBOW, MONOCHROME}.

stirColor

private int stirColor(int color)
