note 42632 added to function.imagecopyresampled

A function to resize any given image to any other specified size, even if it differs in aspect ratio. The created image doesn't look distorted because the algorithm crops the image if necessary to fit in the new size, trying to keep the maximum portion of the original image after cropping. function intelligentshrink($sourcefile, $destfile, $fw, $fh, $jpegquality = 60) { list($ow, $oh, $from_type) = getimagesize($sourcefile); switch($from_type) { case 1: // GIF $srcImage = imageCreateFromGif($sourcefile); break; case 2: // JPG $srcImage = imageCreateFromJpeg($sourcefile); break; case 3: // PNG $srcImage = imageCreateFromPng($sourcefile); break; } $tempw = $fw; $temph = number_format((($oh*$fw)/$ow), 0); if($temph < $fh) { $tempw = number_format((($ow*$fh)/$oh), 0); $temph = $fh; } $tempImage = imageCreateTrueColor($tempw, $temph); imageAntiAlias($tempImage, true); imagecopyresampled($tempImage, $srcImage, 0, 0, 0, 0, $tempw, $temph, $ow, $oh); // Calculate offsets if($temph > $fh) { $offsety = number_format(($temph/2)-($fh/2), 0); $offsetx = 0; } else { $offsety = 0; $offsetx = number_format(($tempw/2)-($fw/2), 0); } $destImage = imageCreateTrueColor($fw, $fh); imagecopyresampled($destImage, $tempImage, 0, 0, $offsetx, $offsety, $fw, $fh, $fw, $fh); imageJpeg($destImage, $destfile, $jpegquality); } ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42632 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42632&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42632&report=yes Search -- http://master.php.net/manage/user-notes.php
