ShapeComp Shape draws a shape into the image, then combines the shape with a background clip. Inputs: Back:  The clip to use as background.

Parameters:

Center:   X & Y,   Default: [360 243],  Range: any.
The center point of the shape. This parameter can be adjusted using the Center Widget.

Size:   Default: 0.5,  Range: 0 or greater.
The overall size of the shape. This parameter can be adjusted using the Size Widget.

Rel Width:   Default: 1,  Range: 0 or greater.
Increase to make the shape wider.

Rel Height:   Default: 1,  Range: 0 or greater.
Increase to make the shape taller.

Rotate:   Default: 0,  Range: any.
Rotates the whole shape around its center. This parameter can be adjusted using the Rotate Widget.

Rotate Pre Scale:   Default: 0,  Range: any.
Rotates the figure around its center before the Rel Width and Rel Height are applied. You can use both rotations to get interesting effects.

Points:   Integer,  Default: 5,  Range: 3 or greater.
The number of points in the shape. Unless Pointiness is zero, the shape will have this many points around the edge.

Pointiness:   Default: 2.15,  Range: any.
How pointy the shape is. 0 gives a circle (as long as Roundness is 1); 1 gives a regular polygon. Greater than 1 gives starlike shapes, and less than zero gives flower-like shapes with outward-facing lobes.

Roundness:   Default: 0,  Range: 0 to 1.
How rounded the edges of the shape are between the points. 0 means straight lines, and 1 means smoothly curved. When Pointiness is 1, this has no effect.

Swirl:   Default: 0,  Range: -5 to 5.
Setting this to nonzero swirls the whole shape around; the outward edge is rotated more than the center to give a vortex-like appearance. Try it with large pointiness.

Blur:   Default: 0,  Range: 0 or greater.
Blurs the whole shape.

Brightness1:   Default: 1,  Range: 0 or greater.
Scales the brightness of the shape.

Color1:   Default rgb: [1 1 1].
The color of the shape.

Color0:   Default rgb: [0 0 0].
The color of the background of the shape image.

Offset0:   Default: 0,  Range: any.
Adds this value to color0.

Combine:   Popup menu,  Default: Screen.
Determines how the shape image is combined with the Background.

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

Mult:  the shape image is multiplied by the Background.

Add:  the shape image is added to the Background.

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

Difference:  the result is the difference between the shape image and Background.

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

Scale Back:   Default: 1,  Range: any,  Shared.
Scales the brightness of the background before combining with the shapes. If 0, the result will contain only the shape image over black.
