Struct GpuBlendEffect 

pub struct GpuBlendEffect {
    pub transition: GpuTransition,
    pub progress: f32,
}

GPU混合特效描述

封装了GPU过渡特效的完整参数，便于传递和复用。 提供便捷的工厂方法创建各种过渡效果。

Example

// 方式1: 使用new
let effect = GpuBlendEffect::new(GpuTransition::Ripple, 0.5);

// 方式2: 使用工厂方法
let effect = GpuBlendEffect::ripple(0.5);
let effect = GpuBlendEffect::dispersion(0.3);

// 调用blend_rts
ctx.adapter.blend_rts(0, 1, 2, effect.effect_type(), effect.progress);

Fields

transition: GpuTransition

过渡特效类型

progress: f32

过渡进度 (0.0 = 完全显示src1, 1.0 = 完全显示src2)

Implementations
