User Manual

 Maximum: Comparing the input mask’s values and the new mask displays the highest
(maximum) value.
 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.
Center X and Y
These controls adjust the position of the ranges mask.
Fit Input
This menu is used to select how the image source is treated if it does not fit the dimensions of
the generated mask.
For example, below, a 720 x 576 image source (yellow) is used to generate a
1920 x 1080 mask (gray).
 Crop: If the image source is smaller than the generated mask, it is placed according to
the X/Y controls, masking off only a portion of the mask. If the image source is larger
than the generated mask it is placed according to the X/Y controls and cropped off at
the borders of the mask.
 Stretch: The image source is stretched in X and Y to accommodate the full dimensions
of the generated mask. This might lead to visible distortions of the image source.
