CogEllipticalAnnulusSection.RadialScale Property

CogEllipticalAnnulusSection RadialScale Property

Cognex VisionPro 9.8 SR1

Returns/sets the radial scaling factor. The elliptical annulus section contains a 'start' arc, and an 'end' arc that is a scaled copy of it. If RadialScale is greater than 1 the end arc will be larger than the start arc, otherwise it will be smaller.

Remarks

Sets or gets the radial scale of this annulus section.

The radial scale determines the relative sizes of the two arcs that make up the annulus section. The two arcs are scaled copies of each other. The start arc is specified by setting the AngleStart and AngleSpan properties. The end arc is specified by applying a radial scale to the start arc.

RadialScale determines which arc is the inner arc and which arc is the outer arc. It also implies a radial direction as shown :

Effect of RadialScale Values

If RadialScale is less than 1:

Start Arc: OuterEnd Arc: InnerRadial Direction: Toward the center

If RadialScale is greater than 1:

Start Arc: InnerEnd Arc: OuterRadial Direction: Away from the center

RadialScale cannot be exactly 1.0, nor can it be less than or equal to zero.

Default Value: 0.5
