title: Quality drop from 2nd frame GIF Resize Magick.NET
body: <p>I'm trying to resize a gif using Magick.NET.
  This gif has 80 frames and resizing it with the code below causes every frame after the first to be extremely blurry and only a little over half of the file size of the first frame.</p>
  
  <p>The only things that change between the first &amp; second frame + everything after that are :</p>
  
  <pre><code>ColorType : TrueColor to TrueColorAlpha
  BoundingBox.X : 1 to 2
  BoundingBox.Y : 0 to 1
  FileSize : 15525 to 9923
  HasAlpha : false to true
  </code></pre>
  
  <p>This is the code i'm using now:</p>
  
  <pre><code>        using (MagickImageCollection collection = new MagickImageCollection(filepath))
          {
              collection.Coalesce();
              int i = 0;
  
              foreach (MagickImage image in collection)
              {
                  image.Resize(newWidth, newHeight);
                  image.Write("CompressorTemp\\" + i + ".jpg");
                  i++;
              }
  
              // Save the result
              collection.Write(filepath);
          }
  </code></pre>
  
  <p>I've only had this happen to this gif but I'll be processing a large amount of them and need to know if this will be an issue.</p>
