note 114944 added to imagick.compareimages

The *Absolute Error* metric is not listed as an available metric constant. However, you can still use it if needed by passing the internal constant definition for AE which is 1. This is useful when you wish to compare using a desired fuzz factor. Example: <?php // init the image objects $image1 = new imagick(); $image2 = new imagick(); // set the fuzz factor (must be done BEFORE reading in the images) $image1->SetOption('fuzz', '2%'); // read in the images $image1->readImage("php_step29_actual.png"); $image2->readImage("php_step29_correct.png"); // compare the images using METRIC=1 (Absolute Error) $result = $image1->compareImages($image2, 1); // print out the result echo "The image comparison 2% Fuzz factor is: " . $result[1]; ?> ---- Server IP: 72.52.91.14 Probable Submitter: 69.53.237.72 ---- Manual Page -- http://php.net/manual/en/imagick.compareimages.php Edit -- https://master.php.net/note/edit/114944 Del: integrated -- https://master.php.net/note/delete/114944/integrated Del: useless -- https://master.php.net/note/delete/114944/useless Del: bad code -- https://master.php.net/note/delete/114944/bad+code Del: spam -- https://master.php.net/note/delete/114944/spam Del: non-english -- https://master.php.net/note/delete/114944/non-english Del: in docs -- https://master.php.net/note/delete/114944/in+docs Del: other reasons-- https://master.php.net/note/delete/114944 Reject -- https://master.php.net/note/reject/114944 Search -- https://master.php.net/manage/user-notes.php
