GD lib Help!

[Anon]

I'm trying to create a dynamic image system for my school band, except my images are being warped somehow. I don't know if it's the code or the server's implementation of the GD lib. Here's the code:

<?php
Header("Content-Type: image/png");
$im = ImageCreateFromPNG("field.png");
$im_out = ImageCreate(420,420);
$bg = ImageColorAllocate($im_out, 255, 255, 255);
ImageCopy($im_out, $im, 0, 0, 0, 0, 420, 420);
ImagePNG($im_out);
ImageDestroy($im_out);
ImageDestroy($im);
?>

The code works, with the exception of the warped image. You can see the result at http://mchstubas.nexen.net/jpegtest.php. Any help is appreciated.

Have a look at field.png. Is that image 420x420?

Doesn't look like it to me!

I am quite aware that field.png is not 420x420, it is 920x420. I am trying to copy a 420x420 portion over to $im_out. In the final version, this portion will be centered on a specific point on the field. Even with $im_out set to 920x420, the image warps. I can't understand it.

To add on to my previous post, the image will warp with even the following simple code:

<?php
Header("Content-Type: image/png");
$im = ImageCreateFromPNG("field.png");
ImagePNG($im);
ImageDestroy($im);
?>

Please help!
