I confirm it too. I found where is the problem. I will try to fix it
before the next release.

Verified with latest CVS, this however appears to be an issue with the
GD library itself since the problem is not particular to the bundled
GD.

Below is a simple test script that illustates the problem. You might
need to change the path for the fonts to suit your setup.
The script strokes a text and then draws the bounding box around the
text. For angle = 0 the bounding box is correct but for any other angle
it is off proportional to the angle.
(With GD 2.01 this is correct but for higher versions the problem
exists)
/Johan
<?php
DEFINE('TTF_DIR','/usr/X11R6/lib/X11/fonts/truetype/');
$w=400; $h=300;
$img = @imagecreatetruecolor($w,$h);
$black = imagecolorallocate ($img, 0, 0, 0);
$white = imagecolorallocate ($img, 255, 255, 255);
$red = imagecolorallocate ($img, 255, 0, 0);
imagefilledrectangle($img,0,0,$w,$h,$white);
$font = TTF_DIR.'arial.ttf';
$font_size = 14;
$txt = 'Some dummy text';
$x = 75; $y=250;
// For angle == 0 the TTF box is correct
$angle = 90;
imagettftext($img,$font_size,$angle,$x,$y,$black,$font,$txt);
$bbox = imagettfbbox(14,$angle,$font,$txt);
// Drwa the bounding box
imageline($img,$x+$bbox[0],$y+$bbox[1],$x+$bbox[2],$y+$bbox[3],$red);
imageline($img,$x+$bbox[0],$y+$bbox[1],$x+$bbox[6],$y+$bbox[7],$red);
imageline($img,$x+$bbox[6],$y+$bbox[7],$x+$bbox[4],$y+$bbox[5],$red);
imageline($img,$x+$bbox[4],$y+$bbox[5],$x+$bbox[2],$y+$bbox[3],$red);
header("Content-type: image/png");
imagepng($img);
/*
print_r($bbox);
On SuSE 8.0 this gives (for angle=90):
PHP 4.2.3 With GD 2.01 gives [CORRECT]:
Array ( [0] => 3 [1] => -1 [2] => 3 [3] => -154
[4] => -16 [5] => -154 [6] => -16 [7] => -2 )
PHP 4.2.3 With GD 2.08 gives [WRONG]:
Array ( [0] => -1 [1] => 13 [2] => -1 [3] => -153
[4] => -17 [5] => -153 [6] => -17 [7] => 13 )
PHP 4.3.0 With built-in GD gives [WRONG]:
Array ( [0] => -1 [1] => 13 [2] => -1 [3] => -153
[4] => -17 [5] => -153 [6] => -17 [7] => 13 )
PHP 4.3.1-dev (2002-02-07) [WRONG]
Array ( [0] => -1 [1] => 13 [2] => -1 [3] => -153
[4] => -17 [5] => -153 [6] => -17 [7] => 13 )
