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, this checkbox
affects all pixels, regardless of whether the new mask covers them.
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 Rectangle mask.
Width and Height
Use these controls to change the X or Y scale of the rectangular effect mask independently of
each other. Alternatively, drag the edges of the rectangle in the viewer to interactively
adjust its size.
Corner Radius
Corner Radius allows the corners of the Rectangle mask to be rounded. A value of 0.0 is not
rounding at all, which means that the rectangle has sharp corners. A value of 1.0 applies the
maximum amount of rounding to the corners.
Angle
Change the rotation angle of an effect mask by moving the Angle control left or right. Values
can be entered in the provided input boxes. Alternatively, use the onscreen controls by
dragging the little circle at the end of the dashed angle line to interactively adjust the rotation of
the ellipse.
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.
