limitingConeAngle property

  • Artículo

Gets a value that specifies a limiting cone that restricts the region where the light is projected.

This property is read-only.

 

Syntax

HRESULT get_limitingConeAngle(
  [out] SVGAnimatedNumber **<number>
);

Property values

Type: SVGAnimatedNumber

An SVGAnimatedNumber object that specifies a limiting cone.

Standards information

Remarks

No light is projected outside the cone.

The ISVGFESpotLightElement::limitingConeAngle attribute represents the angle in degrees between the spot light axis (that is, the axis between the light source and the point to which it is pointing at) and the spot light cone. An anti-aliasing technique is applied at the boundary of the cone.

If no value is specified for the ISVGFESpotLightElement::limitingConeAngle attribute, then no limiting cone will be applied.
