[2006-02-13 15:59 UTC] linuxrocks at gmail dot com

Description:
------------
Using the GD Driver on WinXP, PHP 4.4, GD gives the following error when display() is called:

Warning: imagepng(): Invalid filename '' in E:\htdocs\libs\pear\Image\Transform\Driver\GD.php on line 464

If the second argument from line 464 is removed so:
$result = $functionName($this->imageHandle, $filename);

becomes:
$result = $functionName($this->imageHandle);

The error will disappear and the script will function as expected. However, I suspect that this patch may break saving.

Test script:
---------------
<?php
require_once ("Image/Transform.php");
$b =& Image_Transform::factory('gd');

$b->load ("logo.png");
$b->display();
?>

Expected result:
----------------
Image displays.

Actual result:
--------------
Warning: imagepng(): Invalid filename ''

This is also the case on freebsd
