[Cooker] Probleme with Apache and lib GD on image creation

[Laurent Saint-Michel]

Hello,

While loking for some problem with a gallery package, I just encounter a 
strange behaviour of apache2/libgd2, please have a look to the test program I 
used : 


tata.php :

<?php
  header ("Content-type: image/png");
 $im = @imagecreate(2500, 1000)
    or die ("Cannot use GD");
 $background_color = imagecolorallocate ($im, 255, 255, 255);
 $text_color = imagecolorallocate ($im, 233, 14, 91);
 imagestring ($im, 1, 5, 5,  "A Very Simple test ", $text_color);
 imagepng ($im);

?>

titi.php :
 <?php
  header ("Content-type: image/png");
 $im = @imagecreatetruecolor(2500, 1000)
    or die (" Cannot use GD");
 $background_color = imagecolorallocate ($im, 255, 255, 255);
 $text_color = imagecolorallocate ($im, 233, 14, 91);
 imagestring ($im, 1, 5, 5,  "A Very Simple test ", $text_color);
 imagepng ($im);

?>

et enfin 

toto.php :
 <?php
  header ("Content-type: image/png");
if (function_exists('imagecreatetruecolor'))
{
 $im = @imagecreatetruecolor(2500, 1000)
    or die ("Cannot use GD");
 $background_color = imagecolorallocate ($im, 255, 255, 255);
 $text_color = imagecolorallocate ($im, 233, 14, 91);
 imagestring ($im, 1, 5, 5,  "A Very Simple test ", $text_color);
 imagepng ($im);
}

else {
$im = @imagecreate(2500, 1000)
    or die ("Cannot use lib GD");
  $background_color = imagecolorallocate ($im, 255, 255, 255);
  $text_color = imagecolorallocate ($im, 233, 14, 91);
  imagestring ($im, 1, 5, 5,  "A Very Simple test ", $text_color);
  imagepng ($im);
}
?>

And now if I run the progs, the output are  : 

[EMAIL PROTECTED] temp]$ php -f tata.php
PNG
▒
IHDR    
ÄèÀ£ý}PLTEÿÿÿé[Ë£ÁIDATxíÒ!nÂ`ÆáÙÚLmÑL`j0KÝŠm³+ì»Ã5▒nÁEv&KŸ4{üòæþÔCQGcU<ånÔ×]Ì,7VêïíÇë°ZìϹ[Š¥ì
 
»k^6շϺÛÛÏs3l/¹[Š%u׶œëtªr·LNÑE»ÿå/Æå7ßIEND®B`

(it is png picture)

[EMAIL PROTECTED] temp]$ php -f titi.php
[EMAIL PROTECTED] temp]$

and:

[EMAIL PROTECTED] temp]$ php -f toto.php
[EMAIL PROTECTED] temp]$

The programs titi.php and toto.php have no output and I just get an empty file 
if the direct them to a file.


If I change a little bit  toto.php, we can check that the function :
if (function_exists('imagecreatetruecolor'))
returns TRUE .

If I change the test case in toto to : 
if (function_exists('imagecreatetruecolor') && @imagecreatetruecolor(0,0)) 
the program is using the imagecreate function 

php info returns: 
PHP Version 4.3.3

and lib   gd
