S_Shape

Draws a shape into the image. It can give a wide variety of shapes, from polygons and circles to stars, flower shapes, and swirled starfish shapes. The main parameters to look at are Points, Pointiness, Roundness, and Swirl.

In the Sapphire Render effects submenu.


Inputs:

Background:  Optional.   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.

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

Points:   Integer,  Default: 5,  Range: 3 to 500.
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.

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.

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.

Bg Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the background before combining with the shapes. If 0, the result will contain only the shape image over black.

Combine:   Popup menu,  Default: Over.
Determines how the shape image is combined with the Background.
Shape 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.
Over:  composites the shape image over the background.

Show Rotate: Check-box, Default: on.
