Method Detail
-
create
public static OvalRoi create(double x, double y, double width, double height)
Creates an OvalRoi.
-
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:
getFeretValuesin classRoi
-
moveHandle
protected void moveHandle(int sx, int sy)- Overrides:
moveHandlein classRoi
-
drawPixels
public void drawPixels(ImageProcessor ip)
Draws an outline of this OvalRoi on the image.- Overrides:
drawPixelsin classRoi- See Also:
ImageProcessor.setColor(java.awt.Color),ImageProcessor.setLineWidth(int)
-
getPolygon
public Polygon getPolygon()
Returns this OvalRoi as a Polygon that outlines the mask, in image pixel coordinates.- Overrides:
getPolygonin classRoi- 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:
getFloatPolygonin classRoi
-
getFloatPolygon4
public FloatPolygon getFloatPolygon4()
Returns this OvalRoi as a 4 point FloatPolygon (x,y,w,h).
-
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:
containsPointin 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
public ImageProcessor getMask()
Description copied from class:RoiAlways returns null for rectangular Roi's
