Summary: imageTTFText text shifted right
Status: Closed

New Comment:
The fix for this bug was reverted in revision 296693, which fixed bug
#51263. Re-applying the patch for this bug will break the alignment of
angled text, so another solution is required.
Test script:
<?php
$expected = imagettfbbox(24, 0, 'courier', 'Foobar');
$img = imagecreatetruecolor(100, 100);
$color = imagecolorallocate($img, 0, 0, 0);
$actual = imagettftext($img, 24, 0, 0, 0, $color, 'courier', 'Foobar');
var_dump($expected);
var_dump($actual);
?>
Expected:
$expected equals $actual
Actual result:
array(8) {
[0]=>
int(-1)
[1]=>
int(-1)
[2]=>
int(108)
[3]=>
int(-1)
[4]=>
int(108)
[5]=>
int(-21)
[6]=>
int(-1)
[7]=>
int(-21)
}
array(8) {
[0]=>
int(0)
[1]=>
int(0)
[2]=>
int(109)
[3]=>
int(0)
[4]=>
int(109)
[5]=>
int(-20)
[6]=>

Just noticed that the text positioning between the two examples is
exactly the same - it's the bounding coordinates that changed. This
suggests that in <=5.2.9 BOTH the text and the boxes were shifted right
(which was less noticeable in practice since they were in sync - but a
closer inspection of the 5.2.9 example does show this). The bounding
coordinates are now where one would expect them to be, but that's not
where the text is.

Tabe, can you take a look at this bug please? The only change in this
area was the latest patch about bbox.

Here's the correct result produced by the same code example with 5.2.9:
