从流数据转成Sprite,需要使用Texture2D作为中转
1.从sprite 转换到bytes[]
public byte[] GetByte(Sprite sp)
{
//转换成Texture
Texture2D temp = sp.texture;
//在转换成bytes
byte[] photoByte = temp.EncodeToPNG();
return photoByte;
}
2. 从bytes[] 转换到Sprite
public Sprite GetSprite(Byte[] bytes)
{
//先创建一个Texture2D对象，用于把流数据转成Texture2D
Texture2D texture = new Texture2D(10, 10);
texture.LoadImage(bytes);//流数据转换成Texture2D
//创建一个Sprite,以Texture2D对象为基础
Sprite sp = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero);
return sp;
}
