resize van upload foto

[sjoerdjek]

k heb een code die zorgt dat mijn logo over een foto komt.
nu wil ik graag ook dat hij hem eerst schaalt maar ik kom er niet uit...
kan iemand me daarbij in de goede richting helpen
??

Hier onder het script

<?php
  //--------------------------------
if(isset($_POST['upload'])){

	  define( 'WATERMARK_OVERLAY_IMAGE', 'watermerk.png' );
	  define( 'WATERMARK_OVERLAY_OPACITY', 50 );

	  function create_watermark( $source_file_path, $output_file_path )
	  {
	   list( $source_width, $source_height, $source_type ) = getimagesize( $source_file_path );
	
	   if ( $source_type === NULL )
	   {
		return false;
	   }
