GlowAuraComp In the S_GlowsComp Plugin. Generates radial colored aura lines following the gradient of the source clip. This is similar to GlowAura, but here the source and background can be different clips. Inputs: Front:  The clip to use as foreground. Back:  The clip to combine the glows with. Matte:  Specifies the opacities of the Front clip. These values are scaled by the Source Opacity parameter before being used.

Parameters:

Width:   Default: 0.5,  Range: 0 or greater.
Scales the glow distance. This parameter 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.

Frequency:   Default: 8,  Range: 0 or greater.
The frequency of the color pattern. Increase for more cycles through the spectrum.

Frequency Red:   Default: 1,  Range: 0 or greater.
Scales the red frequency.

Frequency Green:   Default: 1,  Range: 0 or greater.
Scales the green frequency.

Frequency Blue:   Default: 1,  Range: 0 or greater.
Scales the blue frequency.

Subpixel:   Check-box,  Default: off.
Enables glowing by subpixel widths. Use this for smoother animation of the Width parameters.

Phase:   Default: 0,  Range: any.
Shifts the color pattern.

Phase Speed:   Default: 1,  Range: any.
If non-zero, the color phase is automatically animated at this speed, causing the color pattern to flow over time.

Phase Red:   Default: 0.2,  Range: any.
Shifts the red phase.

Phase Green:   Default: 0.1,  Range: any.
Shifts the green phase.

Phase Blue:   Default: 0,  Range: any.
Shifts the blue phase.

Twist:   Default: 1,  Range: any.
Adjusts the spiral direction of the radial lines.

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:   Default rgb: [0 0 0].
Glows will be generated from locations in the source clip that are brighter than this value. A value of 0.9 causes glows at only the brightest spots. A value of 0 causes glows on every non-black area.

Outer Brightnss:   Default: 1,  Range: 0 or greater.
Scales the brightness of the glows at further distances from the source.

Glow Saturation:   Default: 1,  Range: 0 or greater.
Scales the saturation of the glow colors. Increase for more intense colors. Set to 0 for monochrome.

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

Scale Back:   Default: 1,  Range: 0 to 1,  Shared.
Scales the brightness of the background. This parameter only has an effect if the background input is provided, and is visible due to a partially transparent Source image or a reduced Source Opacity parameter value.

Params2:

Glow Under Src:   Default: 0,  Range: 0 to 1,  Shared.
Set to 1 to composite the Source input over the glows.

Glow From Matte:   Default: 0,  Range: 0 to 1,  Shared.
Set to 1 to generate glows from the alpha channel of the source input instead of the RGB channels. In this case the glows will not pick up color from the source and will typically be brighter. Values between 0 and 1 interpolate between using the RGB and the Alpha.

Light Back:   Default: 0,  Range: 0 to 1,  Shared.
Increase this to give a look of the glow casting light onto the background image. To see this more clearly you can also lower the Scale Background parameter or raise the Brightness parameter.

Comp Premult:   Check-box,  Default: off,  Shared.
Enable this for a better composite if the Front pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.

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.
