The problem is, that PHP-GTK was not compiled against PHP with bundled GD library.
It means at the time when PHP-Gtk for windows has been compiled , the PHP libraries used for compiling didn't contain gd. You can't change that.
Btw, the new_from_gd code is very buggy currently and works only on PPC processors (not your x86) correctly. So you've gotta wait for a new version. |

| leon, you don't need gd to load pictures from the net. Just use copy them via copy() into a temporary file (tempnam()) and load the pixbuf from there. |

Hi, if you want to load online image from net without temp file you can try the code below but only small images. This is only example.
| Code: |
function loadPixbuff(&$data){
if(!$im=@imagecreatefromstring($data)) return null;
$X=imagesx($im);
$Y=imagesy($im);
$pb = new GdkPixbuf(Gdk::COLORSPACE_RGB, false, 8, $X, $Y);
for($wY=0; $wY<$Y; $wY++){
for($wX=0; $wX<$X; $wX++){
$rgb_a = imagecolorsforindex($im, imagecolorat($im, $wX, $wY));
$pb->fill_area($wX, $wY, 1, 1,
(($rgb_a['red'] << 24)
+ ($rgb_a['green'] << 16)
+ ($rgb_a['blue'] << 8) + $rgb_a['alpha'])
); // fill_area
} // for
} // for
imagedestroy($im);
return $pb;
} // fnc
