Bug Type: GD related
Operating System: windows 2000/sp3
PHP Version: 4.3.0RC4
New Comment:
I have the same kinf of problem under IIS5, W2K SP4, PHP 4.3.3
After multiple display, I've got this error on all GD images:
imagettfbbox(): Could not set character size
The first problem is that I usally have broken GD images. But if I do a
right-click + Show image, it comes back.
And I don't know the reason of this problem...
Thanks for your help
We are also having problem under Apache/PHP4.3.3 under W2K...
So, is GD2 really stable ?
Thanks,
David
Here is my script :
<?
require("./../configuration/configuration.php");
$largeur_txt = 6;
$taille_txt = 7;
$fontfile = "c:\WINNT\FONTS\arial.ttf";
Header("Content-type: image/png");
$matrice = "./../images/".$couleur ."_" .$style .".png";
$lg_matrice_cote = 12;
$lg_matrice_centre = 10;
$string = stripslashes($text);
If (strlen($string) >= 2) {
// size, angle, font file, text
$tab = imagettfbbox($taille_txt,0,$fontfile,$string);
$largeur_txt = $tab[2];
}
$lg = $largeur_txt + 26;
$ht = 17;
$lg_dst_milieu = $largeur_txt + 2;
$x_dst_d = $lg_dst_milieu + $lg_matrice_cote - 1;
$x_src_d = $lg_matrice_cote + $lg_matrice_centre;
$im_dst = imagecreate($lg,$ht);
$im_src = imagecreatefrompng($matrice);
imagecopyresized($im_dst, $im_src, 0, 0, 0, 0, $lg_matrice_cote, $ht,
$lg_matrice_cote, $ht);
imagecopyresized($im_dst, $im_src, $lg_matrice_cote, 0,
$lg_matrice_cote, 0, $lg_dst_milieu, $ht, $lg_matrice_centre, $ht);
imagecopyresized($im_dst, $im_src, $x_dst_d, 0, $x_src_d, 0,
$lg_matrice_cote, $ht, $lg_matrice_cote, $ht);
$red = hexdec(substr($couleur_text,0,2));
$green = hexdec(substr($couleur_text,2,2));
$blue = hexdec(substr($couleur_text,4,2));
$couleur = ImageColorAllocate($im_dst, $red, $green, $blue);
if ($style == "l") {
$px = $lg_matrice_cote + 3;
} else {
$px = $lg_matrice_cote - 6;
}
if ($style == "b") {
$py = $taille_txt + 4;
} else {
$py = $taille_txt + 3;
}
imagettftext($im_dst,$taille_txt,0,$px,$py,$couleur,$fontfile,$string);
Imagepng($im_dst,'',100);
ImageDestroy($im_dst);
?>

I have problems too, the same OS (Win2k sp3) with php_gd.dll and
php_gd2.dll and php 4.2.3 & php 4.3.0RC4
php installed as an Apache 1.3.24 module
I use the gd only to produce small png, and i get error using
imagettfbbox with this script:
--------
<?php
Header("Content-type: image/png");
$angle = 0;
$font_size = 11;
$font_file="font/arial.ttf";
$taille=imagettfbbox(1, $angle, $font_file, $text);
$hauteur = 2*$font_size;
$largeur = abs($taille[0]-$taille[4]) + 1.5*$hauteur;
$img = imagecreate($largeur,$hauteur);
$bleu = imagecolorallocate($img, 57, 50, 139
$coul_texte = imagecolorallocate($img, 255, 255, 255);
//text alignement...
if...
//returns $x_text and $y_text
imagettftext($img, $font_size, $angle, $x_text, $y_text, $coul_texte,
$font_file, $text);
imagepng($img);
imagedestroy($img);
?>
---------
the results :
- php 4.2.3 with php_gd.dll
99% CPU used and a lot of ram, forced to stop apache service
nothing appears in the php error log.
- php 4.2.3 with php_gd2.dll
"Unable to find font" warning, with a relative link to the font or with
an absolute link.
no image is drawn.
- php 4.3.0RC4 with php_gd.dll
99% CPU used and a lot of ram, forced to stop apache service
nothing appears in the php error log.
- php 4.3.0RC4 with php_gd2.dll
"Could not set character size" warning... Don't know why... And the
strange thing is that sometimes the image is drawn, and sometimes not.
the script worked before on php 4.2.1, gd2, apache 1.3.?.

Small note, TTF library is not thread safe, meaning that in Win32
enviroment it may not operate well.

Hello!
I made crash tests using WebRoller software.
I set to 10 requests my PHP code from 50 virtual clients
simultaneously, and run 40 iterations.
I test php with php_gd.dll and php_gd2.dll.
in second case apache generates error on windows console (GPF)
I use next code:
<?php
error_reporting(E_ALL);
$img="tab100x25.png";
header("content-Type: image/png");
$text ="qwe";
$textlen = strlen($text);
$im = ImageCreateFromPng($img);
$tab_color = ImageColorAllocate($im, 255, 255, 255);
$txt_color = ImageColorAllocate($im, 0,0,0);
$itSize=GetImageSize($img);
$t_size = 11;
ImageFill($im, 9 , 17, $tab_color);
ImageTTFText($im, $t_size, 0, 10, 10, $txt_color,
"arial.ttf", $text);
ImagePng($im);
ImageDestroy($im);
?>
after crash test my system was frosen,apache haves 99% CPU and a lot of
memory.
As next, I comment string with ImageTTFText function and test it
again.
Apache lives!
Below I will provide output from WebRollers test results:
