Scratched my head for a while trying to figure out why this only returned a list of coloured pixels, and seemingly no colour count. Well it turns out that for some reason, the ImagickPixel class has a "getColorCount" method, which seems a strange place for it but hey. <?php $image = new Imagick("thing.png"); $pixels=$image->getImageHistogram(); foreach($pixels as $p){ $colors = $p->getColor(); foreach($colors as $c){ print( "$c\t" ); } print( "\t:\t" . $p->getColorCount() . "\n" ); } ?> This will print out something like: 252 250 252 1 : 125 194 156 182 1 : 126 109 18 79 1 : 11440 2 117 162 1 : 12761 255 255 255 1 : 40769 ...where the colums are red, green, blue, alpha, followed by the number of times that colour appears in the image. ---- Server IP: 109.169.40.147 Probable Submitter: 93.97.186.229 ---- Manual Page -- http://www.php.net/manual/en/function.imagick-getimagehistogram.php Edit -- https://master.php.net/note/edit/104514 Del: integrated -- https://master.php.net/note/delete/104514/integrated Del: useless -- https://master.php.net/note/delete/104514/useless Del: bad code -- https://master.php.net/note/delete/104514/bad+code Del: spam -- https://master.php.net/note/delete/104514/spam Del: non-english -- https://master.php.net/note/delete/104514/non-english Del: in docs -- https://master.php.net/note/delete/104514/in+docs Del: other reasons-- https://master.php.net/note/delete/104514 Reject -- https://master.php.net/note/reject/104514 Search -- https://master.php.net/manage/user-notes.php
