      Sorry, Joey, that is not correct. There are no compression
      settings for png images anywhere in GrADS. You may be confused
      with the compression level that is hard-coded for writing out
      netcdf-4 files. 
      <div><br>
      </div>
      <div>The png files generated by GrADS 2.1+ are large; I use the
        external utility pngquant to shrink them. For more info about
        about pngquant and GrADS, do a google search with
        “site:gradsusr.org pngquant”

                    Dear Grads users,<br>
                    <br>
                    is it possible to reduce png file size from Grads by
                    setting png <br>
                    quality/compression?<br>
                    <br>
