imaqMakeAnnulus

NI Vision for LabWindows/CVI Function

imaqMakeAnnulus

Usage

Annulus imaqMakeAnnulus(Point center, int innerRadius, int outerRadius, double startAngle, double endAngle);

Purpose

Returns an Annulus structure with the values you specify. The Annulus structure defines the location and size rotation of an annulus. You can embed a call to imaqMakeAnnulus() in calls to other NI Vision functions that require Annulus structures as input parameters, thereby eliminating the need to declare an Annulus variable.
