機能/意味
Whether the image has changed

Layerクラスのプロパティ (読み書き可能)
説明
 Indicates whether the image of the layer has changed. You can also set a value.
 It is automatically set to true when you draw on the layer image or change the size of the layer image.
 If you set this property to false, it will be true when the layer image changes, so you can know if the layer image has changed.
 This property itself does not affect the behavior of the layer.
