note 52542 added to function.imagecopyresampled

This snippet allows you to grab a thumbnail from the center of a large image. This was used for a client photo gallery for art to give a teaser of the image to come (only a small portion). You could get dynamic with this value. I also put in a scaling factor in case you want to scale down first before chopping. <?php // The file $filename = 'moon.jpg'; $percent = 1.0; // if you want to scale down first $imagethumbsize = 200; // thumbnail size (area cropped in middle of image) // Content type header('Content-type: image/jpeg'); // Get new dimensions list($width, $height) = getimagesize($filename); $new_width = $width * $percent; $new_height = $height * $percent; // Resample $image_p = imagecreatetruecolor($imagethumbsize , $imagethumbsize); // true color for best quality $image = imagecreatefromjpeg($filename); // basically take this line and put in your versin the -($new_width/2) + ($imagethumbsize/2) & -($new_height/2) + ($imagethumbsize/2) for // the 2/3 position in the 3 and 4 place for imagecopyresampled // -($new_width/2) + ($imagethumbsize/2) // AND // -($new_height/2) + ($imagethumbsize/2) // are the trick imagecopyresampled($image_p, $image, -($new_width/2) + ($imagethumbsize/2), -($new_height/2) + ($imagethumbsize/2), 0, 0, $new_width , $new_width , $width, $height); // Output imagejpeg($image_p, null, 100); ?> ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52542 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52542&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52542&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52542&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52542&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52542&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52542&report=yes Search -- http://master.php.net/manage/user-notes.php
