In this example $im is the source image <? //calculate thumb size $ow = imagesx($im); $oh = imagesy($im); $maxh = 100; $maxw = 150; $new_h = $oh; $new_w = $ow; if($oh > $maxh || $ow > $maxw){ $new_h = ($oh > $ow) ? $maxh : $oh*($maxw/$ow); $new_w = $new_h/$oh*$ow; } //create dst image $dst_img = ImageCreateTrueColor($new_w,$new_h); //resize and copy image ImageCopyResized($dst_img, $im, 0,0,0,0, $new_w, $new_h, ImageSX($im), ImageSY($im)); $function_image_new($dst_img,$galdir.$file); ?> ---- Manual Page -- http://www.php.net/manual/en/function.imagecreate.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48738 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48738&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48738&report=yes Search -- http://master.php.net/manage/user-notes.php
