Syntax
Members
| Member name | Value | Description | |
|---|---|---|---|
| None | 0 | Disables interactive manipulation of the elliptical annulus section. | |
| EndPoints | 1 | Enables interactive manipulation of the endpoints of the manipulation arc in the annulus section. Notice that changing an endpoint is likely to affect the center, radii, rotation, start, span and radial scale of the annulus, but not the other endpoint. | |
| SectionSpan | 2 | Enables interactive manipulation of the arc length of the elliptical annulus section. Either end of the section can be slid along the underlying ellipse, without changing ellipse's center, radii, or rotation. | |
| Bend | 4 | Enables interactive manipulation of the curvature of the annulus section. Changing the curvature is likely to affect the center, radii, rotation, start, span and radial scale of the annulus, but will not modify the endpoints of the manipulation arc. | |
| ConstrainedSpan | 8 | Enables interactive manipulation of the curvature of the elliptical annulus section while constraining the manipulation arc to pass through the endpoints and the bend handle. Changes the fraction of the full ellipse that appears between the endpoints. | |
| Radii | 16 | Enables interactive manipulation of the radii of the elliptical annulus section. Changing one radius will not affect the center, rotation, start or span of the annulus, nor will it modify the other radius. | |
| SectionSpanFourPi | 32 | If interactive manipulation of the annulus section's span is enabled, setting this bit allows the span to vary between 4 * Pi and -4 * Pi. The limits for interactive manipulation are 2 * Pi and -2 * Pi if this bit is not set. | |
| Position | -2147483648 | Enables interactive manipulation of the X,Y position of the elliptical annulus section. Changing the position will not affect the radii, rotation, start, span or radial scale of the annulus. | |
| All | -1 | Enables interactive manipulation of all degrees of freedom for the elliptical annulus section. |
