Looks like smoothing is not working or something is missing in the code. Maybe Matrix should have something more?</p> <p>Original image:</p> <p><a href="http://imageshack.us/a/img28/4784/dc7f2ec4b0f3323cdc4e01e.jpg" rel="nofollow">http://imageshack.us/a/img28/4784/dc7f2ec4b0f3323cdc4e01e.jpg</a></p> <p>and it's result:</p> <p><a href="http://imageshack.us/a/img855/4784/dc7f2ec4b0f3323cdc4e01e.jpg" rel="nofollow">http://imageshack.us/a/img855/4784/dc7f2ec4b0f3323cdc4e01e.jpg</a></p> <p>I can link a bunch of others images. Some strange pixel disposition exist. Can it be fixed somehow?</p> <p>I have tested jpeg quality 100% and stage.quality='best', but none of them give the required quality outcome.</p>
