Changed to PHP5 now script doesnt work

[willpower]

Hi. 

 

I had a dynamic img creation with gdlib and Right Alignment.  I 'pinched' this script which worked well until my host upgraded to php5. Any ideas.  the following error messages are received.

 

‰PNG IHDR2ý~Ê

Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error in /home/clearcon/public_html/fonts/title.php on line 40

 

Warning: imagepng() [function.imagepng]: gd-png error: setjmp returns error condition in /home/clearcon/public_html/fonts/title.php on line 40

 

Heres the code

 

<?php
header("Content-type: image/png");
$text = str_replace("_"," ",$_GET['title']);
$font = "DAX-REGU.TTF";
$size = 22;
$angle = 0;


//check width of the text
$bbox = imagettfbbox ($size, $angle, $font, $text);
$bbox["left"] = 0- min($bbox[0],$bbox[2],$bbox[4],$bbox[6]);
$bbox["top"] = 0- min($bbox[1],$bbox[3],$bbox[5],$bbox[7]);
$bbox["width"] = max($bbox[0],$bbox[2],$bbox[4],$bbox[6]) - min($bbox[0],$bbox[2],$bbox[4],$bbox[6]);
$bbox["height"] = max($bbox[1],$bbox[3],$bbox[5],$bbox[7]) - min($bbox[1],$bbox[3],$bbox[5],$bbox[7]);
extract ($bbox, EXTR_PREFIX_ALL, 'bb');


//check width of the image
$insert = imagecreatetruecolor(400,50);
//choose textcolor (white)

$width = imagesx($insert);
$height = imagesy($insert);
$pad = 2;

$white=imagecolorallocate($insert,255,255,255);
$col=imagecolorallocate($insert,55,27,66);
imagefilltoborder ( $insert, 0, 0, $white,$white );
//write text
// top:
//imagettftext($insert, $size, $angle, $width/2-$bb_width/2, $bb_top+$pad, $col, $font, $text);
// left:
//imagettftext($insert, $size, $angle, $bb_left+$pad, $height/2-$bb_height/2, $col, $font, $text);
// bottom:
//imagettftext($insert, $size, $angle, $width/2-$bb_width/2, $height-$bb_height-$pad, $col, $font, $text);
// right:
imagettftext($insert, $size, $angle, $width-$bb_width-$pad, 22, $col, $font, $text);
//output picture

imagepng($insert,"",100);
imagedestroy($insert);
exit; 
?>

My gut feeling is that it's a problem with your hosting provider's libraries.  I recommend sending the error to them.

 

Then again, I know very little about the GD libraries .. I'm sure someone else is better placed to advise.

 

You might also want to try changing the "" in the imagepng() call to null, as that is what is specified in the documentation for imagepng():

 

imagepng($insert, null, 100);

I tried your posted script using PHP Version 5.0.5 and it worked fine, without error.
