S_TextureChromaSpiral Creates an abstract texture by applying a WarpChroma effect to a procedurally generated noise texture. In the Sapphire Render effects submenu. Inputs: Background:  The current layer.   The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only.

Parameters:

Noise Frequency:   Default: 6,  Range: 0.01 or greater.
The spatial frequency of the initial noise texture. Increase to zoom out, decrease to zoom in.

Noise Octaves:   Integer,  Default: 3,  Range: 1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the amplitude of the previous. A single octave gives a smooth texture. Adding octaves makes the result approach a fractal (1/f) noise texture.

Noise Shift:   X & Y,   Default: [0 0],  Range: any.
Translation offset of the initial noise texture.

Noise Seed:   Default: 0.23,  Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Center:   X & Y,   Default: [360 243],  Range: any.
The center location of the chroma warp, in screen coordinates relative to the center of the frame.

Z Dist:   Default: 0.7,  Range: 0.001 or greater.
The distance that the chroma warp effect is applied over.

Rotate:   Default: -8,  Range: any.
The rotation of the spiral, in degrees. Set to 0 for a straight zoom.

Steps:   Integer,  Default: 12,  Range: 3 to 100.
The number of color samples along the spectrum to include. More steps give a smoother result, but require more time to process.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the result.

Color:   Default rgb: [1 1 1].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.

Offset:   Default: 0,  Range: -8 to 2.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.

Bg Brightness:   Default: 1,  Range: 0 or greater.
The background brightness is scaled by this value before being combined with the texture.

Combine:   Popup menu,  Default: Texture Only.
Determines how the texture is combined with the Background.

Texture Only:  gives only the texture image with no Background.

Mult:  the texture is multiplied by the Background.

Add:  the texture is added to the Background.

Screen:  the texture is blended with the Background using a screen operation.

Difference:  the result is the difference between the texture and Background.

Overlay:  the texture is combined with the Background using an overlay function.

Input Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Output Opacity:   Popup menu,  Default: Copy From Input.
Determines the opacity/transparency of the result. This effect does not process the opacity (alpha channel) of its input but it can either copy the opacity from the input, or output a fully opaque result.

All Opaque:  Makes the result fully opaque with no transparency.

Copy From Input:  Copies the opacity/transparency from the current layer given to this effect.
