"imagecreatetruecolor" question please

[limi]

hello,

I'm trying to turn a swf file into a jpeg.
the swf movie works fine and when i click a button to call on a php page that converts it to a jpeg an error msg comes up saying that magecreatetruecolor is undefined.
I searched for a solution online and realized i should try to use imagecreate instead (something with GD support). it still gave me the same msg.
i tried to add "@" before the action name and then the page came up w/o error but it was blank! no jpeg image of my swf.
here is that part of the code:

$image = @imagecreatetruecolor(300,200);
$imagelines = @imagecreate(300,200);

(as mentioned i tried it with and w/o the "@&quot
in my code the imagecreatetruecolor appears black (like it doesn't
recognize it) but the imagecreate is blue; nevertheless, the "undefined" error message still come up.

what could it be?
how do i define it?
Thank you,

Are you sure that the GD libraries are loaded with your php config? In my php.ini I have the line:
extension=php_gd.dll
This is commented out by default.

Do a search in your php.ini of "gd" and see if its just been commented out.

I should point out that this is on a WinXP machine. Its probably different if you are using linux
