Example: Using a Single Math Tool to Generate Multiple Results
This example illustrates the requirements for configuring a math tool to
generate multiple results from a window tool using a black contours
operation to generate multiple results. When configured for
Multiple
operation, a single math tool can thus generate the same number of results as
an equivalent number of math tools using
Single operation.
When you pick the Operation field in the math tool edit panel while
“ Single ” is displayed, the field will toggle to “ Multiple ,” as shown in
Figure 7.114.

Note that the Loops field and the button become active when
Multiple operation is selected.
In this example, it is assumed that the window tool and math tool are entered
in the toolset edit panel as shown in Figure 7.115. It is also assumed that the
window tool is configured to use the black contours operation to generate the
“area” results values of a maximum of 15 objects (for details about window
contours operations, see the White Contours; Black Contours section on page
7–40 of this chapter).

After the button has been picked to access the formula entry
keyboard, the formula for acquiring the “area” results values is entered into
the keyboard as shown in Figure 7.116 (page 7–145).
