Interface IGradient

Namespace: IronPPT.Interfaces

Assembly: IronPPT.dll

Syntax

public interface IGradient

Filling a shape or background with a smooth color blend in C# runs through IGradient. The contract describes a multi-stop gradient: the colors it passes through, the points where each color sits, and the angle the blend follows. A developer works with it while styling a shape fill, where a flat color is not enough and the look calls for one color easing into another.

A gradient is reached through the fill of the element being styled rather than built in isolation, so an IGradient is usually obtained from the object it decorates and then adjusted. Three members carry the work. StopPoints is a List<IGradientStop> holding each color and its position along the blend, so adding or reordering stops shapes the transition. LinearShadeAngle is an IRotation that sets the direction the gradient runs. LinearShadeScaled, a Nullable<bool>, controls whether the shade scales with the shape. The concrete implementor in IronPPT is the Gradient class, so most code uses Gradient directly and names the interface only when a method should accept any gradient.

gradient.StopPoints.Add(stop);

The add shape example builds a styled shape, and the paragraph style example shows related styling work.
