note 58233 added to function.imagecopyresampled

For an internet photoalbum I was looking for a script which I could simply drop in a directory with images and which would do the rest. Therefor I am using the following resize script now. I have made the little thumb-part because I want to have all the same size thumbnails, but with as less as possible distortion. Therefor, images with other dimensions are resized, but also cut off a little. Als $pictype = thumb, the extra dimension calculations are used $width and $height are the new dimensions of $filename, the image $dest is the directory where the new image must be copied in. The script: // Resize function function resize($filename, $dest, $width, $height, $pictype) { $format = strtolower(substr(strrchr($filename,"."),1)); switch($format) { case 'gif' : $type ="gif"; $img = imagecreatefromgif($filename); break; case 'png' : $type ="png"; $img = imagecreatefrompng($filename); break; case 'jpg' : $type ="jpg"; $img = imagecreatefromjpeg($filename); break; case 'jpeg' : $type ="jpg"; $img = imagecreatefromjpeg($filename); break; default : die ("ERROR; UNSUPPORTED IMAGE TYPE"); break; } list($org_width, $org_height) = getimagesize($filename); $xoffset = 0; $yoffset = 0; if ($pictype == "thumb") // To minimize destortion { if ($org_width / $width > $org_height/ $height) { $xtmp = $org_width; $xratio = 1-((($org_width/$org_height)-($width/$height))/2); $org_width = $org_width * $xratio; $xoffset = ($xtmp - $org_width)/2; } elseif ($org_height/ $height > $org_width / $width) { $ytmp = $org_height; $yratio = 1-((($width/$height)-($org_width/$org_height))/2); $org_height = $org_height * $yratio; $yoffset = ($ytmp - $org_height)/2; } } $img_n=imagecreatetruecolor ($width, $height); imagecopyresampled($img_n, $img, 0, 0, $xoffset, $yoffset, $width, $height, $org_width, $org_height); if($type=="gif") { imagegif($img_n, $dest); } elseif($type=="jpg") { imagejpeg($img_n, $dest); } elseif($type=="png") { imagepng($img_n, $dest); } elseif($type=="bmp") { imagewbmp($img_n, $dest); } Return true; } ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58233 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58233&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58233&report=yes Search -- http://master.php.net/manage/user-notes.php
