VectorSpiral Class

The horizontal center of the spiral is defined here as either a fixed or scaled value.

The vertical center of the spiral is defined here as either a fixed or scaled value.

The height of the spiral is expressed as Radius * 2.0.

The LoopLimit can be used to impose a limit on the total number of loops that are performed by the spiral path generator. It can be used as an alternative to, or conjunction with the Radius value to limit the final spiral size.

If the LoopLimit is not set, the Radius will take precedence.

The generation of a spiral's path can be offset by specifying a positive value in the Offset field. By default the Offset is set to zero.

The author's computation of the total length of the path, in user units. This value is used to calibrate the user agent's own distance-along-a-path calculations with that of the author. The user agent will scale all distance-along-a-path computations by the ratio of PathLength to the user agent's own computed value for total path length.

The radius of the spiral is defined here as either a fixed or scaled value. If zero, preference is given to LoopLimit.

Spacing tightly controls the computation of the spiral path, ensuring that a specific amount of empty space is left between each loop. The space is declared in pixel units.

If Spacing is undeclared, the spiral expands at an incremental rate of Step * 0.1.

The Step value affects the distance between each vertex in the spiral path during its generation. The default value is 1.0. Using larger values will create a spiral with jagged corners due to the reduction in vertices.

The width of the spiral is expressed as Radius * 2.0.
