Constructor Detail

OvalRoi

public OvalRoi(int x,
               int y,
               int width,
               int height)

Creates an OvalRoi.

OvalRoi

public OvalRoi(double x,
               double y,
               double width,
               double height)

Creates an OvalRoi using double arguments.

OvalRoi

public OvalRoi(int x,
               int y,
               ImagePlus imp)

Starts the process of creating a user-defined OvalRoi.

OvalRoi

public OvalRoi(int x,
               int y,
               int width,
               int height,
               ImagePlus imp)

Deprecated.

Method Detail

getFeretValues

public double[] getFeretValues()

Feret (caliper width) values, see ij.gui.Roi.getFeretValues(). The superclass method of calculating this via the convex hull is less accurate for the MinFeret because it does not get the exact minor axis.

Overrides:

getFeretValues in class Roi

moveHandle

protected void moveHandle(int sx,
                          int sy)

Overrides:

moveHandle in class Roi

draw

public void draw(java.awt.Graphics g)

Overrides:

draw in class Roi

drawPixels

public void drawPixels(ImageProcessor ip)

Draws an outline of this OvalRoi on the image.

Overrides:

drawPixels in class Roi

See Also:

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

getPolygon

public java.awt.Polygon getPolygon()

Returns this OvalRoi as a Polygon that outlines the mask, in image pixel coordinates.

Overrides:

getPolygon in class Roi

See Also:

ImageProcessor.setRoi(java.awt.Rectangle), ImageProcessor.drawPolygon(java.awt.Polygon), ImageProcessor.fillPolygon(java.awt.Polygon)

getFloatPolygon

public FloatPolygon getFloatPolygon()

Returns this OvalRoi as a FloatPolygon approximating the ellipse.

Overrides:

getFloatPolygon in class Roi

size

public int size()

Returns the number of corner points in the mask of this selection; equivalent to getPolygon().npoints.

Overrides:

size in class Roi

contains

public boolean contains(int ox,
                        int oy)

Tests whether the center of the specified pixel is inside the boundary of this OvalRoi. Authors: Barry DeZonia and Michael Schmid

Overrides:

contains in class Roi

containsPoint

public boolean containsPoint(double x,
                             double y)

Returns whether coordinate (x,y) is contained in the Roi. Note that the coordinate (0,0) is the top-left corner of pixel (0,0). Use contains(int, int) to determine whether a given pixel is contained in the Roi.

Overrides:

containsPoint in class Roi

isHandle

public int isHandle(int sx,
                    int sy)

Returns a handle number if the specified screen coordinates are inside or near a handle, otherwise returns -1.

Overrides:

isHandle in class Roi

getMask

public ImageProcessor getMask()

Description copied from class: Roi

Always returns null for rectangular Roi's

Overrides:

getMask in class Roi

getLength

public double getLength()

Returns the perimeter length using Ramanujan's approximation for the circumference of an ellipse

Overrides:

getLength in class Roi
