Bug #72604 imagearc() ignores thickness for full arcs
Submitted: 2016-07-15 17:20 UTC Modified: 2016-07-15 17:21 UTC
From: cmb@php.net Assigned: cmb
Status: Closed Package: GD related
PHP Version: 7.1.0alpha3 OS: *
Private report: No CVE-ID:
 [2016-07-15 17:20 UTC] cmb@php.net
Description:
------------
When full arcs are to be drawn (i.e. $start = 0 and $end = 360),
imagearc() calls gdImageEllipse() internally. However,
gdImageEllipse() does not yet support thickness, so the behavior
is inconsistent with partial arcs.


Test script:
---------------
<?php
$im = imagecreatetruecolor(100, 100);
imagesetthickness($im, 5);
imagearc($im, 50, 50, 90, 90, 0, 360, 0xffffff);
imagepng($im, '72603.png');


Expected result:
----------------
A thick arc.

Actual result:
--------------
A thin arc.

This bug does not affect external libgd, which does not use the
gdImageEllipse() optimization.
