   15 <p>This option is the JPEG/PNG/MIFF compression quality
   16 setting.</p>
   17 <p>For the JPEG image format, quality is 0 (worst) to 100 (best).
   18 The default quality is 75.</p>
   19 <p>Quality for the MIFF and PNG image format sets the amount of
   20 image compression (quality / 10) and filter-type (quality % 10).
   21 Compression quality values range from 0 (worst) to 100 (best). If
   22 filter-type is 4 or less, the specified filter-type is used for all
   23 scanlines:</p>
   24 <pre class="text">
   25   0: none
   26   1: sub
   27   2: up
   28   3: average
   29   4: Paeth
   30 </pre>
   31 <p>If filter-type is 5, adaptive filtering is used when quality is
   32 greater than 50 and the image does not have a color map, otherwise
   33 no filtering is used.</p>
   34 <p>If filter-type is 6 or more, adaptive filtering with
   35 <em>minimum-sum-of-absolute-values</em> is used.</p>
   36 <p>The default is quality is 75. Which means nearly the best
   37 compression with adaptive filtering.</p>
