Subject: Re: [PHP-DEV] PHP 8.1.0RC6 available for testing
From: come@chilliet.eu (=?ISO-8859-1?Q?C=F4me?= Chilliet)

Hello,

I have a difference in behavior between PHP 8.1 RC6 and my system PHP for t=
he function imagettfbbox.
It is hard to know if this is a problem with 8.1 really because I had to do=
wnload and build imagick through pecl to be able to run this.

<?php
$font =3D '/usr/share/fonts/truetype/noto/NotoSans-Regular.ttf';
var_dump(imagettfbbox(12, 0, $font, 'E'));

The result for running this is:
$ ~/dev/php-src-git/sapi/cli/php ~/dev/test-freetype.php
array(8) {
  [0]=3D>
  int(1)
  [1]=3D>
  int(0)
  [2]=3D>
  int(8)
  [3]=3D>
  int(0)
  [4]=3D>
  int(8)
  [5]=3D>
  int(-12)
  [6]=3D>
  int(1)
  [7]=3D>
  int(-12)
}
$ php ~/dev/test-freetype.php
array(8) {
  [0]=3D>
  int(0)
  [1]=3D>
  int(1)
  [2]=3D>
  int(10)
  [3]=3D>
  int(1)
  [4]=3D>
  int(10)
  [5]=3D>
  int(-12)
  [6]=3D>
  int(0)
  [7]=3D>
  int(-12)
}

As you can see the resulting bounding box is not the same, for the same fon=
t. This messes up our avatar generation, which ends up a few pixels wrong o=
n the centering of the initial in the image.

Does anyone knows where this can come from, and if by changing how I build/=
link imagick I can get the same result on both binaries?
