Median
Depending on which Filter Type is selected, the Median control may appear. It varies the
Median filter’s effect. A value of 0.5 produces the true median result, as it finds the middle
values. A value of 0.0 finds the minimums, and 1.0 finds the maximums. This applies to the
Median setting only.
Seed
This control is visible only when applying the Grain or Noise filter types. The Seed slider can be
used to ensure that the random elements of the effect are seeded with a consistent value. The
randomizer always produces the same result, given the same seed value.
Animated
This control is visible only when applying the Grain or Noise filter types. Select the checkbox to
cause the noise or grain to change from frame to frame. To produce static noise, deselect
this checkbox.
Common Controls
Settings Tab
The Settings tab controls are common to all Filter nodes, so their descriptions can be found in
“The Common Controls” section at the end of this chapter.
Rank Filter Node [RFlt]
The RankFilter node
Rank Filter Node Introduction
The Rank Filter examines nearby pixels, sorts the pixels by value, and then replaces the color of
the examined pixels with the color of the pixel with the selected rank.
Inputs
The Rank Filter node includes two inputs: one for the main image and the other for an effect
mask to limit the area where the filter is applied.
Input: The orange input is used for the primary 2D image that gets the Rank filter
applied.
Effect Mask: The optional blue effect mask input accepts a mask shape created
by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.
Connecting a mask to this input limits the rank filter to only those pixels within the
mask. An effects mask is applied to the tool after the tool is processed.
