hyperspy.drawing._markers.rectangle module

class hyperspy.drawing._markers.rectangle.Rectangle(x1, y1, x2, y2, **kwargs)

Bases: MarkerBase

Rectangle marker that can be added to the signal figure

Parameters
  • x1 (array or float) – The position of the up left corner of the rectangle in x. If float, the marker is fixed. If array, the marker will be updated when navigating. The array should have the same dimensions in the navigation axes.

  • y1 (array or float) – The position of the up left corner of the rectangle in y. see x1 arguments

  • x2 (array or float) – The position of the down right corner of the rectangle in x. see x1 arguments

  • y2 (array or float) – The position of the down right of the rectangle in y. see x1 arguments

  • kwargs – Keyword arguments are passed to matplotlib.patches.Rectangle . Note that the ‘color’ keyword is used as the alias of ‘edgecolor’ for backward compatibility.

Example

>>> import scipy.misc
>>> im = hs.signals.Signal2D(scipy.misc.ascent())
>>> m = hs.plot.markers.rectangle(x1=150, y1=100, x2=400, y2=400,
>>>                               color='red')
>>> im.add_marker(m)

Adding a marker permanently to a signal

>>> im = hs.signals.Signal2D(np.random.random((50, 50))
>>> m = hs.plot.markers.rectangle(x1=20, y1=30, x2=40, y2=49)
>>> im.add_marker(m, permanent=True)
