GradientAngleGeometry class abstract

An abstract base class for representing gradient angles with alignment geometry.

GradientAngleGeometry provides an interface for converting between angular representation and alignment-based gradients. It supports both directional (text-direction-aware) and non-directional gradient angles.

Subclasses should implement how to calculate begin and end alignments based on the angle value.

Implementers

• DirectionalGradientAngle
• GradientAngle

Constructors
