Emission Alpha Cutoff: When the Image Source object contains an alpha channel, this slider
defines the minimum opacity value necessary to create an element at that point on the source
image. For example, when set to 25%, elements only appear at points where the alpha value of
the image is equal to or greater than 25% opacity. The lower the Emission Alpha Cutoff value,
the more cells appear. For this parameter to be effective, the alpha channel must have areas of
varying transparency.

•
Start Point: This parameter is available when Shape is set to Line or Wave. Two value sliders
define, in X, Y, and Z coordinates, the first point of the line or wave on which the elements are
positioned. Click the disclosure triangle to access the Z Start Point value slider. You can adjust
these values in the Canvas using the onscreen controls (with the Adjust Item tool).
•
End Point: This parameter is available when Shape is set to Line or Wave. Two value sliders
define, in X, Y, and Z coordinates, the second point of the line or wave on which the elements
are positioned. Click the disclosure triangle to access the Z Start Point value slider. You can
adjust these values in the Canvas using the onscreen controls (with the Adjust Item tool).
•
Amplitude: This slider, available only when Shape is set to Wave, defines half the distance from
the highest point to the lowest point in the wave. Higher values result in more extreme waves.
•
Frequency: This slider, available only when Shape is set to Wave, defines the number of waves.
The default is value is 1.

•
Phase: This slider, available only when Shape is set to Wave. A dial defines the degree of offset
of the waves from the start and end points of the path. When set to 0 degrees (default), the
wave begins and ends at half the distance from the highest point to the lowest point in the
wave. When set to 90 degrees, the wave begins and ends at the highest point in the wave.
When set to –90 degrees, the wave begins at the lowest point in the wave. When set to 180
degrees, the waves are the same as 0 degrees, but inverted.
