Description

PixelElementSelect is a selection method that selects Elements in response to a mouse click in the graphics window when the Skeleton Selection toolbox is active and is set to “Element” mode. It selects all Elements with the same dominant pixel type as the pixel that was selected with the mouse. See Figure 6.17 for some examples.

skeleton is the Skeleton from which the Elements are to be selected.

points is a list of Point objects. PixelElementSelect will select those Elements whose dominant pixel category is the same as that of the pixel containing the first point in the list.

The shift and ctrl parameters govern how the current selection (i.e, the set of Elements defined by this operation) is merged with the previous selection (the Elements already selected) to form a new selection, as shown in Table 6.1. They indicate whether (1) or not (0) the shift and control keys were depressed during the mouse click that initiated this command.

Figure 6.17. Selecting Elements by Pixel Type

A Skeleton for a Microstructure with three pixel types (shown by shades of blue and yellow).

Clicking on the point shown selects all the elements (shown in red) whose dominant pixel is yellow.

The mouse indicates a pixel that is not the dominant type for the element surrounding it.

Clicking on a non-dominant (submissive?) pixel does not select the element in which the mouse was clicked!
