java.lang.Objectij.gui.Roi
ij.gui.ShapeRoi
public class ShapeRoi
A subclass of ij.gui.Roi
(2D Regions Of Interest) implemented in terms of java.awt.Shape.
A ShapeRoi is constructed from a ij.gui.Roi
object, or as a result of logical operators
(i.e., union, intersection, exclusive or, and subtraction) provided by this class. These operators use the package
java.awt.geom
as a backend.
This code is in the public domain.

Method Summary | |
---|---|
static void |
addCircle(java.lang.String sx,

java.lang.String swidth)
|
ShapeRoi |
and(ShapeRoi sr)
Unary intersection operator. |
java.lang.Object |
clone()
Returns a deep copy of this. |
boolean |
contains(int x,
int y)
Checks whether the specified coordinates are inside a on this ROI's shape boundaries. |
void |
draw(java.awt.Graphics g)
Non-destructively draws the shape of this object on the associated ImagePlus. |
void |
drawPixels(ImageProcessor ip)
Draws the shape of this object onto the specified ImageProcessor. |
void |
drawRoiBrush(java.awt.Graphics g)
|
java.awt.Polygon |
getConvexHull()
Always returns null. |
double[] |
getFeretValues()
Caculates "Feret" (maximum caliper width) and "MinFeret" (minimum caliper width). |
double |
getLength()
Returns the length of this shape (perimeter, if shape is closed). |
ImageProcessor |
getMask()
Returns this ROI's mask pixels as a ByteProcessor with pixels "in" the mask set to white (255) and pixels "outside" the mask set to black (0). |
Roi[] |
getRois()
Converts a Shape into Roi object(s). |
java.awt.Shape |
getShape()
Returns a reference to the Shape object encapsulated by this ShapeRoi. |
float[] |
getShapeAsArray()
Retrieves the end points and control points of the path as a float array. |
int |
isHandle(int sx,
int sy)
Always returns -1 since ShapeRois do not have handles. |
ShapeRoi |
not(ShapeRoi sr)
Unary subtraction operator. |
ShapeRoi |
or(ShapeRoi sr)
Unary union operator. |
Roi |
shapeToRoi()
Attempts to convert this ShapeRoi into a non-composite Roi. |
static void |
subtractCircle(java.lang.String sx,
java.lang.String sy,
java.lang.String swidth)
|
ShapeRoi |
xor(ShapeRoi sr)
Unary exclusive or operator. |
