Unity Texture 2D相关操作

• 保存Texture 2D到本地

  var bytes = tex2D.EncodeToPNG();
  // Application.dataPath为Asset文件夹路径
  File.WriteAllBytes(Application.dataPath + "/Resources/Test/SavedScreen2.png", bytes);
  

• 旋转

  RotateTexture2D.RotateSquare(tex2D, 180.0f);
  

• Texture转Texture2D
  RawImage的纹理类型是Texture

  Texture2D tex2D = tex as Texture2D;
  

• Texture2D转Base64字符串

      public string Texture2DToBase64(Texture2D tex)
      {
          byte[] bytesArr = tex.EncodeToJPG();
          string strbaser64 = Convert.ToBase64String(bytesArr);
          return strbaser64;
      }
  

• Base64字符串转Texture2D

  public Texture2D Base64ToTexture2D(string Base64Str)
  {
      Texture2D pic = new Texture2D(190, 190, TextureFormat.RGBA32, false);
      byte[] data = System.Convert.FromBase64String(Base64Str);
      pic.LoadImage(data);
      return pic;
  }
