Lav 100x100 hvidt billede hvor resized billede indsættes på

Jeg irritere mig tit over at jeg få oprettet et spørgsmål og derefter finder svaret 2 min efter.

<?php
// The file
$filename = '4923107_4929107_4921507_hardbeat_orginal.jpg';

// Set a maximum height and width
$width = 100;
$height = 10;

$thumbsize = 100;

// Content type
header('Content-type: image/jpeg');

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
  $width = $height*$ratio_orig;
} else {
  $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($thumbsize, $thumbsize);
$image = imagecreatefromjpeg($filename);

$white = ImageColorAllocate($image, 255, 255, 255);
ImageFill($image_p, 0, 0, $white);


imagecopyresampled($image_p, $image, -($width/2) + ($thumbsize/2), -($height/2) + ($thumbsize/2), 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);
?>
