New Comment:
I also experience the problem with PHP 4.3.2 and bundled GD version
'2.0.12 compatible'. Recompiled with Debian package version
(2.0.12-2... damn!) and same problem (obviously). It seems to be some
how proportional to the angle of the text; smaller angles yield more
accuracy.
My implementation:
<?
$res = imagecreatetruecolor(400, 400);
$white = imagecolorallocate($res, 0xff, 0xff, 0xff);
$red = imagecolorallocate($res, 0xcc, 0x00, 0x00);
$blue = imagecolorallocate($res, 0x00, 0x00, 0xcc);
imagefill($res, 0, 0, $white);
for ($angle = 0; $angle < 360; $angle += 60)
{
$wrong1 = imagettftext($res,20,$angle,200,200,$blue,
"/usr/share/fonts/truetype/Courier_New.ttf",
"ABCDEF 12345");
$t = imagettfbbox(20, $angle,
"/usr/share/fonts/truetype/Courier_New.ttf",
"ABCDEF 12345");
$wrong2 = array(200+$t[0],200+$t[1],200+$t[2],
200+$t[3],200+$t[4],200+$t[5],200+$t[6],200+$t[7]);
imagepolygon($res,$wrong2,count($wrong2)/2,$red);
imagepolygon($res,$wrong1,count($wrong1)/2,$red);
}
header("Content-type: image/png");
imagepng($res);
?>

I'm experiencing the same problem, using php 4.3.2 with GD 2.0.15
Normal text (with no rotation) results in a correct bounding box, but
as soon as I rotate the text, it goes wrong, no matter which font I
use.
Here's a sample code which displays a text with it's bounding box at 0,
90, 180 and 170 degrees:
<?php
$image=imagecreate(500, 500);
$imagedum=imagecreate(500, 500);
$color1=imagecolorallocate($image, 0xff, 0xff, 0xff);
$color2=imagecolorallocate($image, 0x3f, 0x3f, 0x3f);
$color3=imagecolorallocate($image, 0xff, 0x00, 0x00);
for ($angle=0; $angle<360; $angle+=90) {
$text="ABCpqrs";
$font = "./verdana.ttf";
// Draw the text into the image:
$result=imagettftext($imagedum, 30, $angle, 250, 250, $color2,
$font, $text);
imagettftext($image, 30, $angle, 250, 250, $color2,
$font, $text);
// Draw the bounding-box into the image:
imageline($image, $result[0], $result[1], $result[2], $result[3],
$color3);
imageline($image, $result[2], $result[3], $result[4], $result[5],
$color3);
imageline($image, $result[4], $result[5], $result[6], $result[7],
$color3);
imageline($image, $result[6], $result[7], $result[0], $result[1],
$color3);
}
// Draw the image to the screen:
header("Content-Type: image/jpeg");
imagejpeg($image);
imagedestroy($image);
imagedestroy($imagedum);
?>

Just checked with 4.3.2RC3 and the problem still exists.

This problem still exists in 4.3.2RC2. This returns yet another set of
(wrong) coordinates for the bounding box.
With 4.3.2RC2 (Compiled on SuSE 8.2) gives the following wrong return
array:
Array ( [0] => -1 [1] => 14 [2] => -1 [3] => -146
[4] => -17 [5] => -146 [6] => -17 [7] => 14 )
Which is again different from what was returned in 4.3.1

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