CircularAnnulusROI

class glue.core.roi.CircularAnnulusROI(xc=None, yc=None, inner_radius=None, outer_radius=None)

Bases: Roi

A 2D circular annulus region of interest.

Parameters:

xcfloat, optional

x coordinate of center.

ycfloat, optional

y coordinate of center.

inner_radiusfloat, optional

Inner radius of the circular annulus.

outer_radiusfloat, optional

Outer radius of the circular annulus.

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 annulus region.
to_polygon()	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

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.

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.

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 annulus region.

to_polygon()

Returns vertices vx, vy of a polygon approximating the Roi, where each is an array of vertex coordinates in x and y.

transformed(xfunc=None, yfunc=None)

A transformed version of the Roi
