Reproduced error on the following:
* PHP Version 5.2.5
* GD Library bundled (2.0.34 compatible)
** IIS 5.1 on Windows XP Professional
** Apache/2.2.9 (Win32) on Windows XP Professional
Reproduce code:
<?php
$radius = 100;
$corner_image = imagecreatetruecolor(
$radius * 2,
$radius * 2
);
$clear_colour = imagecolorallocate(
$corner_image,
0,
0,
0
);
$solid_colour = imagecolorallocate(
$corner_image,
0xFF,
0,
0
);
imagefill(
$corner_image,
0,
0,
$solid_colour
);
imagefilledellipse(
$corner_image,
$radius,
$radius,
$radius * 2,
$radius * 2,
$clear_colour
);
header( "Content-type: image/png" );
imagepng( $corner_image );
?>
Expected output:
* 200x200 black circle inside 200x200 red square, perfect fit
Actual output:
* 201x201 black circle inside 200x200 red square, the right side of
circle clearly appears "clipped"

I can confirm this still occurs in PPH 5.2.9-1
An elipse with an even size is rounded to an odd size

The same effect occurs for the imageellipse(), I belive this bug is in
libgd
