mne.viz.ClickableImage

class mne.viz.ClickableImage(imdata, **kwargs)

Display an image so you can click on it and store x/y positions.

Takes as input an image array (can be any array that works with imshow, but will work best with images. Displays the image and lets you click on it. Stores the xy coordinates of each click, so now you can superimpose something on top of it.

Upon clicking, the x/y coordinate of the cursor will be stored in self.coords, which is a list of (x, y) tuples.

__hash__(/)	Return hash(self).
onclick(event)	Handle Mouse clicks.
plot_clicks(**kwargs)	Plot the x/y positions stored in self.coords.
to_layout(**kwargs)	Turn coordinates into an MNE Layout object.

onclick(event)

Handle Mouse clicks.

Parameters

eventmatplotlib.backend_bases.Event

The matplotlib object that we use to get x/y position.

plot_clicks(**kwargs)

Plot the x/y positions stored in self.coords.

Parameters

**kwargsdict

Arguments are passed to imshow in displaying the bg image.

to_layout(**kwargs)

Normalizes by the image you used to generate clicks

Parameters

**kwargsdict

Arguments are passed to generate_2d_layout.
