Hello,
I have a difference in behavior between PHP 8.1 RC6 and my system PHP for the function imagettfbbox.
It is hard to know if this is a problem with 8.1 really because I had to download and build imagick
through pecl to be able to run this.
<?php
$font = '/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]=>
int(1)
[1]=>
int(0)
[2]=>
int(8)
[3]=>
int(0)
[4]=>
int(8)
[5]=>
int(-12)
[6]=>
int(1)
[7]=>
int(-12)
}
$ php ~/dev/test-freetype.php
array(8) {
[0]=>
int(0)
[1]=>
int(1)
[2]=>
int(10)
[3]=>
int(1)
[4]=>
int(10)
[5]=>
int(-12)
[6]=>
int(0)
[7]=>
int(-12)
}
As you can see the resulting bounding box is not the same, for the same font. This messes up our
avatar generation, which ends up a few pixels wrong on 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?
