Description

Select a contiguous circular region of pixels with the mouse.

The source parameter is the path to a Microstructure or Image. If it's an Image, the selection is made in the Microstructure in which the Image resides.

The points parameter is a Python list of Points in the Microstructure, indicating the mouse motion. The first point is the center of the circle, and the last is a point on is perimeter. Any other points in the list will be ignored.

The shift and ctrl parameters govern how the current selection (i.e, the set of objects defined by this operation) is merged with the previous selection (the objects already selected) to form a new selection, as shown in Table 6.1. They indicate whether (True) or not (False) the shift and control keys were depressed during the mouse click that initiated this command.
