User Manual

 Average: This calculates the average (half the sum) of the new mask
and the input mask.
 Multiply: This multiplies the values of the input mask by the new mask’s values.
 Replace: The new mask completely replaces the input mask wherever they intersect.
Areas that are zero (completely black) in the new mask do not affect the input mask.
 Invert: Areas of the input mask that are covered by the new mask are inverted; white
becomes black and vice versa. Gray areas in the new mask are partially inverted.
 Copy: This mode completely discards the input mask and uses the new
mask for all values.
 Ignore: This mode completely discards the new mask and uses the input
mask for all values.
Invert
Selecting this checkbox inverts the entire mask. Unlike the Invert Paint mode, the checkbox
affects all pixels, regardless of whether the new mask covers them or not.
Solid
When the Solid checkbox is enabled, the mask is filled to be transparent (white) unless inverted.
When disabled, the spline is drawn as just an outline whose thickness is determined by the
Border Width slider.
Center X and Y
These controls adjust the position of the polygon spline mask.
Size
Use the Size control to adjust the scale of the polygon spline effect mask, without affecting the
relative behavior of the points that compose the mask or setting a keyframe in the mask
animation.
X, Y, and Z Rotation
Use these three controls to adjust the rotation angle of the mask along any axis.
Fill Method
The Fill Method menu offers two different techniques for dealing with overlapping regions of a
polyline. If overlapping segments in a mask are causing undesirable holes to appear, try
switching the setting of this control from Alternate to Non Zero Winding.
Right-Click Here for Shape Animation
By default, all polygon spline masks are animated when they are created. The initial keyframe is
set to the current time, and any changes to the shape at different times create new keys.
Right-clicking on this label displays a contextual menu that offers options for removing or
re-adding animation to the mask, or publishing and connecting the masks together.
Common Controls
Image and Settings Tabs
The Image and Settings tabs in the Inspector are also duplicated in other mask nodes. These
common controls are described in detail at the end of this chapter in “The Common
Controls” section.
