imagecopyresampled and imagecopyresized problems

hello guys.

i dont get any image when the following code is run.. i dont know. but i copied them from the php manual itself. is something wrong with my gd library?

<?php
// The file you are resizing
$file = 'http://localhost/try.jpg';

//This will set our output to 45% of the original size
$size = 0.45;

// This sets it to a .jpg, but you can change this to png or gif
header('Content-type: image/jpeg');

// Setting the resize parameters
list($width, $height) = getimagesize($file);
$modwidth = $width * $size;
$modheight = $height * $size;

// Creating the Canvas
$tn= imagecreatetruecolor($modwidth, $modheight);
$source = imagecreatefromjpeg($file);

// Resizing our image to fit the canvas
imagecopyresized($tn, $source, 0, 0, 0, 0, $modwidth, $modheight, $width, $height);

// Outputs a jpg image, you could change this to gif or png if needed
imagejpeg($tn);
?>

Code (markup):

and

<?php
// The file
$filename = 'D:\public\try.jpg';
$percent = 0.5;

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

// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = $width * $percent;
$new_height = $height * $percent;

// Resample

// Output
imagejpeg($image_p);
?>

Try:

$filename = 'D:\\public\\try.jpg';

PHP:

If that doesn't work either, use your browser's "view page source" and see if you get any PHP errors.


Oh, and please use

 wrappers instead of [code] wrappers when posting PHP code.
