Overview

A color stop at a specific position in a gradient.

Represents a single color at a position along a gradient. Positions are normalized from 0.0 (start) to 1.0 (end). Multiple stops define the color transitions in a gradient.

Usage

Stop objects are typically created automatically by gradient classes using the .build() method, but can be created directly for more control.

Examples

# Create a stop directly
stop = Unmagic::Color::Gradient::Stop.new(
color: Unmagic::Color::RGB.parse("#FF0000"),
position: 0.5
)

# Access stop properties
stop.color      # => #<RGB...>
stop.position   # => 0.5
