PSDでアニメーションフレームを通じてレイヤーオパシティを変更する方法 .NET を使用

var timeline = psdImage.Timeline;

for (int i = 0; i < timeline.Frames.Length; i++)

    // ...
}

    // ...
}

    var frame = timeline.Frames[i];
    LayerState targetLayerState = frame.LayerStates[1];

}

psdImage.Save(outputFile);
psdImage.Dispose();
