Public Overridable Sub DrawFromCenterRadiusToCenterRadiusOptions ( _ startCenter As NSPoint, _ startRadius As CGFloat, _ endCenter As NSPoint, _ endRadius As CGFloat, _ options As NSGradientDrawingOptions _ )
public: virtual void DrawFromCenterRadiusToCenterRadiusOptions( NSPoint startCenter, CGFloat startRadius, NSPoint endCenter, CGFloat endRadius, NSGradientDrawingOptions options )

- startCenter (NSPoint)
- The center point of the circle that represents the beginning of the gradient.
- startRadius (CGFloat)
- The radius of the circle that represents the beginning of the gradient.
- endCenter (NSPoint)
- The center point of the circle that represents the end of the gradient.
- endRadius (CGFloat)
- The radius of the circle that represents the end of the gradient.
- options (NSGradientDrawingOptions)
- The gradient options, if any. You can use these options to extend the gradient size beyond the start and end circles. For more information, see “Gradient Drawing Options”.

- Available in Monobjc Bridge: 10.6 (For Mac OS X 10.6 and later), 10.5 (For Mac OS X 10.5 and later)
