Method Details
-
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 classRoi
-
moveHandle
protected void moveHandle(int sx, int sy)- Overrides:
moveHandle
in classRoi
-
draw
-
drawPixels
Draws an outline of this OvalRoi on the image.- Overrides:
drawPixels
in classRoi
- See Also:
ImageProcessor.setColor(java.awt.Color)
,ImageProcessor.setLineWidth(int)
-
getPolygon
Returns this OvalRoi as a Polygon that outlines the mask, in image pixel coordinates.- Overrides:
getPolygon
in classRoi
- See Also:
ImageProcessor.setRoi(java.awt.Rectangle)
,ImageProcessor.drawPolygon(java.awt.Polygon)
,ImageProcessor.fillPolygon(java.awt.Polygon)
-
getFloatPolygon
Returns this OvalRoi as a FloatPolygon approximating the ellipse.- Overrides:
getFloatPolygon
in classRoi
-
size
public int size()Returns the number of corner points in the mask of this selection; equivalent to getPolygon().npoints. -
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 -
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 classRoi
-
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. -
getMask
Description copied from class:Roi
Always returns null for rectangular Roi's -
getLength
public double getLength()Returns the perimeter length using Ramanujan's approximation for the circumference of an ellipse
