SweepGradient

Inherits: Gradient

Creates a sweep gradient centered at center that starts at start_angle and ends at end_angle.

More information here.

Properties

• center(Alignment) –

  The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square

• end_angle(Number) –

  The angle in radians at which stop 1.0 of

• start_angle(Number) –

  The angle in radians at which stop 0.0 of

Properties

center class-attribute instance-attribute

center: Alignment = field(default_factory=lambda: CENTER)

The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square describing the gradient which will be mapped onto the paint box.

For example, an Alignment.CENTER will place the sweep gradient in the center of the box.

end_angle class-attribute instance-attribute

end_angle: Number = pi * 2

The angle in radians at which stop 1.0 of the gradient is placed.

start_angle class-attribute instance-attribute

start_angle: Number = 0.0

The angle in radians at which stop 0.0 of the gradient is placed.
