title: Can't convert tiff image to a bitmap (matrix)
body: <p>The function <code>GetBitMapColorMatrix</code> is ‏supposed to decode the tiff image and return a bitmap that describes the tiff image but for some reason, I get this exception -&gt; <code>System.PlatformNotSupportedException: 'System.Drawing is not supported on this platform'</code>. Any help would be appreciated.</p>
  <pre><code>public Color[][] GetBitMapColorMatrix(string bitmapFilePath)
      {
          Bitmap b1 = new Bitmap(bitmapFilePath);
  
          int hight = b1.Height;
          int width = b1.Width;
  
          Color[][] colorMatrix = new Color[width][];
          for (int i = 0; i &lt; width; i++)
          {
              colorMatrix[i] = new Color[hight];
              for (int j = 0; j &lt; hight; j++)
              {
                  colorMatrix[i][j] = b1.GetPixel(i, j);
              }
          }
          return colorMatrix;
      }
  </code></pre>
