GlowDist In the S_Glows Plugin. Generates glows based on the distances from the edges of the source input. Any edges in the input image, where the brightness crosses the given threshold value, will generate an equally bright glow into the darker side of the edges. This is best observed when used on images with dark backgrounds. Inputs: Source:  The input clip that determines the glow locations and colors. This clip is also used as the background and the glows are layered back onto it.

Parameters:

Width:   Default: 0.2,  Range: 0 or greater.
Scales the glow distance. This and all the width parameters can be adjusted using the Width Widget. Note that a zero glow width still enhances the bright areas; set the brightness parameter to zero if you want to pass the Source through unchanged.

Width Red:   Default: 1,  Range: 0 or greater.
Scales the red glow distance. If the red, green, and blue widths are equal, the glows will be a single color given by the Color parameter. If they are not equal, the glows will vary in color with distance.

Width Green:   Default: 1.2,  Range: 0 or greater.
Scales the green glow width.

Width Blue:   Default: 1.4,  Range: 0 or greater.
Scales the blue glow width.

Brightness:   Default: 0.8,  Range: 0 or greater.
Scales the brightness of the glows.

Color:   Default rgb: [1 1 1].
Scales the color of the glows.

Threshold Add Color:   Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the glows generated on areas of the source clip containing that color.

Threshold:   Default: 0.5,  Range: 0 or greater.
Glows are generated at the edges of areas in the source clip that are brighter than this value. A value of 0.9 causes glows from only the brightest spots. A value of 0 causes glows for every non-black area.

Scale Source:   Default: 1,  Range: 0 to 1,  Shared.
Scales the brightness of the Source input when combined with the glows. This does not affect the generation of the glows themselves.

Eclipse With Bg:   Default: 0,  Range: 0 to 1,  Shared.
If this is set to 1, the background is subtracted from the glow and gives an eclipsed shadow effect.

Params2:

Show:   Popup menu,  Default: Result.
Selects the type of output

Result:  Shows the final result of combining the glow, source, and background.

Threshold:  Shows the thresholded image that is used to generate the glow.

Combine:   Popup menu,  Default: Screen.
Determines how the glow is combined with the Source or Background. This parameter has no effect if Light BG is set to 1.

Mult:  the source or background is multiplied by the glow.

Add:  the glow is added to the source or background.

Screen:  the glow is blended with the source or background using a screen operation.

Difference:  the result is the difference between the glow and the source or background.

Overlay:  the glow is combined with the source or background using an overlay function.
