Control Points for DISTORTION_PERSPECTIVE are pairs of x0, y0, x1, y1 coordinates, where x0/y0 is the original point and x1/y1 is the destination point, e.g. for a four point distortion: <?php $im = new imagick( $fn); $w=$im->getImageWidth(); $h=$im->getImageHeight(); $im->setImageFormat('png'); $controlPoints = array( $tLx, $tLy, 0, 0, // top left $tRx, $tRy, $w, 0, // top right $bRx, $bRy, $w, $h, // bottom right $bLx, $bLy, 0, $h // bottom left ); /* Perform the distortion */ $im->distortImage(Imagick::DISTORTION_PERSPECTIVE, $controlPoints, false); // Output the image $output = $im->getimageblob(); $outputtype = $im->getFormat(); header("Content-type: $outputtype"); echo $output; ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.246 (proxied: 2a02:c7f:dc2e:9000:fd8b:d01:a564:fb19) ---- Manual Page -- http://php.net/manual/en/imagick.distortimage.php Edit -- https://master.php.net/note/edit/125815 Del: integrated -- https://master.php.net/note/delete/125815/integrated Del: useless -- https://master.php.net/note/delete/125815/useless Del: bad code -- https://master.php.net/note/delete/125815/bad+code Del: spam -- https://master.php.net/note/delete/125815/spam Del: non-english -- https://master.php.net/note/delete/125815/non-english Del: in docs -- https://master.php.net/note/delete/125815/in+docs Del: other reasons-- https://master.php.net/note/delete/125815 Reject -- https://master.php.net/note/reject/125815 Search -- https://master.php.net/manage/user-notes.php
