Bug Type: GD related
Operating System: *
PHP Version: 5.2.4
Assigned To: pajoye
New Comment:
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

Description:
------------
imagefilledellipse() produces an ellipse with a different size if the
size is even.
Reproduce code:

<?php
$image = imagecreatetruecolor(200, 200);
$color = imagecolorallocate($image, 255, 255, 255);
imagefilledellipse($image, 100, 100, 26, 26, $color);
header("Content-type: image/png");
imagepng($image);
?>
Expected result:
----------------
An ellipse with the size of 26.
Actual result:

An ellipse with the size of 27.
