GlowEdges In the S_Glows Plugin. Creates glowing light from the edges of the source clip. This differs from the default Glow in that small or thin objects generate as much glow around their edges as large objects. Also the glow colors are not affected by the colors of the source clip. Inputs: Source:  Edges are extracted from this input clip to determine the glow locations.

Parameters:

Width:   Default: 0.1,  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 width. If the red, green, and blue widths are equal, the glow colors be uniform with distance. 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.

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

Width X:   Default: 1,  Range: 0 or greater.
Scales the horizontal glow width. Set to 0 for vertical only.

Width Y:   Default: 1,  Range: 0 or greater.
Scales the vertical glow width. Set to 0 for horizontal only.

Edges Smooth:   Default: 0,  Range: 0 or greater.
Determines the width of the extracted edges which generate the glows.

Edges Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the edges before the glows are applied.

Edges Threshold:   Default: 0,  Range: 0 or greater.
Increase to remove glows on the less sharp edges.

Glow Brightness:   Default: 2,  Range: 0 or greater.
Controls the overall glow brightness. Set to zero to get no glow.

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

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:  Normally the glows are combined with the source or background, and output.

EDGES:  The edge image only is output, before any glows are applied. This can be helpful while adjusting the various edge parameters.

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.
