Blend
The Blend slider determines the percentage of the affected image that is mixed with original
image. It blends in more of the original image as the value gets closer to 0.
This control is a cloned instance of the Blend slider in the Common Controls tab. Changes
made to this control are simultaneously made to the one in the common controls.
Apply Mode
Three Apply Modes are available when it comes to applying the glow to the image.
Normal: Default. This mode simply adds the glow directly over top of the original image.
Merge Under: Merge Under places the glow beneath the image, based on the Alpha
channel. Threshold mode permits clipping of the threshold values.
Threshold: This control clips the effect of the glow. A new range slider appears. Pixels
in the glowed areas with values below the low value are pushed to black. Pixels with
values greater than high are pushed to white.
High-Low Range Control: Available only in Threshold mode. Pixels in the glowed areas
with values below the low value are pushed to black. Pixels with values greater than
high are pushed to white.
Color Scale (RGBA)
These Scale sliders can be used to adjust the amount of glow applied to each color channel
individually, by tinting the glow.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other Blur nodes. These common controls
are described in detail at the end of this chapter in “The Common Controls” section.
Sharpen [SHRP]
The Sharpen node
Sharpen Node Introduction
The Sharpen node uses a convolution filter to enhance detail in an image overall or to an
individual channel.
Inputs
The two inputs on the Sharpen node are used to connect a 2D image and an effect mask that
can limit the area affected by the sharpen.
Input: The orange input is used for the primary 2D image for sharpening.
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the sharpen to only those pixels within the mask. An effect mask is applied to
the tool after it is processed.
