Titolo: Fatal error: imagecreate()

Salve a tutti,
Ho un piccolo Problema probbilmente dovuto ad una incorretta 
configurazione di PHP !!!
Stò utilizzando un server Microsoft IIS (Obbligato dall'azienda) e PHP 4.X
Cerco di Generare un Grafico a torta,  lo stesso codice php che scrivo, 
sul mio computer personale "funziona" ed  in azienda non funziona 
(Unica	 Differenza è che sul mio Portatile ho un Server Apache). Mi dà 
questo Errore:-
Fatal error: Call to undefined function: imagecreate() "come se non 
riconoscesse la funzione imagecreate"
Qualcuno sà dirmi perchè?
Mille Grazie

XLV. Image Functions
Introduction
PHP is not limited to creating just HTML output. It can also be used to 
create and manipulate image files in a variety of different image 
formats, including gif, png, jpg, wbmp, and xpm. Even more convenient, 
PHP can output image streams directly to a browser. You will need to 
compile PHP with the GD library of image functions for this to work. GD 
and PHP may also require other libraries, depending on which image 
formats you want to work with.
You can use the image functions in PHP to get the size of JPEG, GIF, 
PNG, SWF, TIFF and JPEG2000 images.
Note: Read requirements section about how to expand image capabilities 
to read, write and modify images and to read meta data of pictures taken 
by digital cameras.
Requirements
If you have the GD library (available at 
http://www.boutell.com/gd/
) you 
will also be able to create and manipulate images.
The format of images you are able to manipulate depend on the version of 
GD you install, and any other libraries GD might need to access those 
image formats. Versions of GD older than gd-1.6 support GIF format 
images, and do not support PNG, where versions greater than gd-1.6 and 
less than gd-2.0.28 support PNG, not GIF. GIF support was re-enabled in 
gd-2.0.28.
Note: Since PHP 4.3 there is a bundled version of the GD lib. This 
bundled version has some additional features like alpha blending, and 
should be used in preference to the external library since its codebase 
is better maintained and more stable.
You may wish to enhance GD to handle more image formats.
Table 1. Supported image formats
Image format Library to download Notes
gif   Only supported in GD versions older than gd-1.6 and newer than 
gd-2.0.28. Read-only GIF support is available with PHP 4.3.0 and the 
bundled GD-library. Write support is avaliable since PHP 4.3.9 and PHP 
5.0.1.
jpeg-6b 
ftp://ftp.uu.net/graphics/jpeg/
png 
http://www.libpng.org/pub/png/libpng.html
 Only supported in GD 
versions greater than gd-1.6.
xpm 
ftp://metalab.unc.edu/pub/Linux/libs/X/!INDEX.html
 It's likely you 
have this library already available, if your system has an installed 
X-Environment.
You may wish to enhance GD to deal with different fonts. The following 
font libraries are supported:
Table 2. Supported font libraries

FreeType 1.x 
http://www.freetype.org/
FreeType 2 
http://www.freetype.org/
T1lib 
ftp://sunsite.unc.edu/pub/Linux/libs/graphics/
) Support for Type 1 
fonts.
If you have PHP compiled with --enable-exif you are able to work with 
information stored in headers of JPEG and TIFF images. This way you can 
read meta data generated by digital cameras as mentioned above. These 
functions do not require the GD library.
Installation
To enable GD-support configure PHP --with-gd[=DIR], where DIR is the GD 
base install directory. To use the recommended bundled version of the GD 
library (which was first bundled in PHP 4.3.0), use the configure option 
--with-gd. GD library requires libpng and libjpeg to compile.
In Windows, you'll include the GD2 DLL php_gd2.dll as an extension in 
php.ini. The GD1 DLL php_gd.dll was removed in PHP 4.3.2. Also note that 
the preferred truecolor image functions, such as imagecreatetruecolor(), 
require GD2.
Note: To enable exif support in Windows, php_mbstring.dll must be loaded 
prior to php_exif.dll in php.ini.
To disable GD support in PHP 3 add --without-gd to your configure line.
Enhance the capabilities of GD to handle more image formats by 
specifying the --with-XXXX configure switch to your PHP configure line.
Table 3. Supported image formats
Image Format Configure Switch
jpeg-6b To enable support for jpeg-6b add --with-jpeg-dir=DIR.
png To enable support for png add --with-png-dir=DIR. Note, libpng 
requires the zlib library, therefore add --with-zlib-dir[=DIR] to your 
configure line.
xpm To enable support for xpm add --with-xpm-dir=DIR. If configure is 
not able to find the required libraries, you may add the path to your 
X11 libraries.
Note: When compiling PHP with libpng, you must use the same version that 
was linked with the GD library.
Enhance the capabilities of GD to deal with different fonts by 
specifying the --with-XXXX configure switch to your PHP configure line.
Table 4. Supported font libraries
Font library Configure Switch
FreeType 1.x To enable support for FreeType 1.x add --with-ttf[=DIR].
FreeType 2 To enable support for FreeType 2 add --with-freetype-dir=DIR.
T1lib To enable support for T1lib (Type 1 fonts) add --with-t1lib[=DIR].
Native TrueType string function To enable support for native TrueType 
string function add --enable-gd-native-ttf.
