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>
