Bug description:horizontal misalignment of characters extending beyond their
left margin
Description:
------------
The following bug is present in PHP 5.2.13 and was not present in PHP
5.2.11. (It was probably introduced while attempting to solve Bug #49600.)
My test bed is Windows XP/Apache 2.0, production site runs on Linux/Apache
1.3, both are showing the same symptom.
We are using the commercial font "Pirouette Text" by Linotype which I
obviously cannot include in this report. What sets this font apart from
most other fonts is the fact that some characters extend horizontally
beyond their bounding boxes in terms of character placement.
My little test script spells out the word "Information" in "Pirouette
Text". In this font the letter "f" (among others) is made up of a large
S-like curve extending well into its neighboring letters
Test script:
---------------
$text = "Information";
$font = "pirouette.otf";
$size = 41;
$dim = imagettfbbox($size, 0, $font, $text);
$off_y = -$dim[7];
$off_x = -$dim[0];
$img_h = $dim[1]+$off_y+1;
$img_w = $dim[2]+$off_x+2;
unset($dim);
$img = imagecreatetruecolor($img_w, $img_h);
imagefilledrectangle($img, 0, 0, $img_w-1, $img_h-1, 0xFFFFFF);
imagettftext($img, $size, 0, $off_x, $off_y, 0x000000, $font, $text);
header("Content-Type: image/gif");
imagetruecolortopalette($img, false, 32);
imagegif($img);
imagedestroy($img);
Expected result:
----------------
This is what it should look like (rendered by PHP 5.2.11):

Actual result:

And this is how PHP 5.2.13 messes it up:
