Thumbnail?
Hvordan bruger jeg nedenstående?<?php
$userfile_name = "images/test.jpg";
$newwidth = 100;
$size = GetImageSize($userfile_name);
$width = $size[0];
$height = $size[1];
$type = $size[2];
$newheight = round($height*$newwidth/$width);
$thumbname = "$userfile_name";
if ($type == 1) {
$src = imagecreatefromgif("$userfile_name");
$im = imagecreate($newwidth,$newheight);
imagecopyresized($im,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
Imagegif($im, $thumbname);
} else if ($type == 2) {
$src = imagecreatefromjpeg("$userfile_name");
$im = imagecreate($newwidth,$newheight);
imagecopyresized($im,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
ImageJPEG($im, $thumbname);
} else if ($type == 3) {
$src = imagecreatefrompng("$userfile_name");
$im = imagecreate($newwidth,$newheight);
imagecopyresized($im,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
Imagepng($im, $thumbname);
} else {
echo "Dette billedformat understøttes ikke";
}
imagedestroy($im);
?>
