====================================
Creating Virtual Images from Vectors
====================================

In this example we will show how to create virtual images from vectors.
We will use the `find_peaks` method to find the vectors and then use the
`get_unique_vectors` method to reduce the number of vectors to a unique set of vectors.

We can convert the unique vectors to regions of interest (ROIs) objects using the `to_roi` method
and then use the `get_virtual_image` method to create the virtual images.

This method is flexible and any type of ROI defined in hyperspy can be used to create virtual images.

We also included the include_labels argument to the `to_roi` method which will also return the labels
for each ROI for use plotting on the signal.
