always black background on generated images

[[email protected]]

Hi,

 

I'm using this code to create an image:

 

// create a blank image

$image = imagecreatetruecolor(400, 300);

$grey = imagecolorallocate($image, 200, 200, 200); 

// fill the background color

$xyz = imagefill($image, 0, 0, $grey);

$xyz = imagecolortransparent($image, $grey);

(...) <--generate some content, which displays properly

// output the picture

imagetruecolortopalette($image, true, 256);

Imagejpeg($image, "myimage.jpg");

 

One one server (Apache, linux) the background always remains black; on other servers the same code generates nice gray background.

How can I fix this ?

Some of the functions require GD2 and are likely generating errors. Add the following two lines after your first <?php tag -

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

No errors pop up on this one...How can I find out what version of GD I'm using on each server ?

Make a php document with this:

 

<?php
phpinfo();
?>

 

Then do a search for "GD Version".
