note 123322 added to imagick.setimagecompressionquality

For a PNG image, setImageCompressionQuality() is not work at all, length of the generated files are totally same. But I found an effective way, that is use setOption('png:compression-level', 9), the value range is 0-9. ---- Server IP: 208.43.231.9 Probable Submitter: 123.118.11.122 ---- Manual Page -- http://php.net/manual/en/imagick.setimagecompressionquality.php Edit -- https://master.php.net/note/edit/123322 Del: integrated -- https://master.php.net/note/delete/123322/integrated Del: useless -- https://master.php.net/note/delete/123322/useless Del: bad code -- https://master.php.net/note/delete/123322/bad+code Del: spam -- https://master.php.net/note/delete/123322/spam Del: non-english -- https://master.php.net/note/delete/123322/non-english Del: in docs -- https://master.php.net/note/delete/123322/in+docs Del: other reasons-- https://master.php.net/note/delete/123322 Reject -- https://master.php.net/note/reject/123322 Search -- https://master.php.net/manage/user-notes.php
