CircularROI#
- class glue.core.roi.CircularROI(xc=None, yc=None, radius=None)[source]#
Bases:
Roi
A 2D circular region of interest.
- Parameters:
- xcfloat, optional
x coordinate of center.
- ycfloat, optional
y coordinate of center.
- radiusfloat, optional
Radius of the circle.
Methods Summary
center
()Return the (x, y) coordinates of the ROI center
contains
(x, y)Test which of a set of (x, y) points fall within the region of interest.
defined
()Returns True if the ROI is defined
move_to
(x, y)Translate the ROI to a center of (x, y)
reset
()Reset the circular region
set_center
(x, y)Set the center of the circular region
set_radius
(radius)Set the radius of the circular region
Returns vertices vx, vy of a polygon approximating the Roi, where each is an array of vertex coordinates in x and y.
transformed
([xfunc, yfunc])A transformed version of the Roi
Methods Documentation
- contains(x, y)[source]#
Test which of a set of (x, y) points fall within the region of interest.
- Parameters:
- xfloat or array-like
x coordinate(s) of point(s).
- yfloat or array-like
y coordinate(s) of point(s).
- Returns:
- insidebool or ~numpy.ndarray
An boolean iterable, where each element is True if the corresponding (x, y) tuple is inside the Roi.
- Raises:
- UndefinedROI
If not defined.
