 |
|
I was going to try image genrating in php so I got this from a tutorial. From what I understand this should work.
The problem is the first time I ran this I got Error 500 then simply refreshing gave me 200 0k. Same after that.
| Code: | <?
$ButtonWidth = 100;
$ButtonHeight = 30;
$ButtonLabel = "Testing";
$ButtonFont = 5;
$image = imagecreate($ButtonWidth, $ButtonHeight);
$colorBody = imagecolorallocate($image, 0x99, 0x99, 0x99);
$colorShadow = imagecolorallocate($image, 0x33, 0x33, 0x33);
$colorHighlight = imagecolorallocate($image, 0xCC, 0xCC, 0xCC);
imagefilledrectangle($image, 1, 1, $ButtonWidth-2, $ButtonHeight-2, $colorBody);
//determine label size
$ButtonLabelHeight = imagefontheight($ButtonFont);
$ButtonLabelWidth = imagefontwidth($ButtonFont) * strlen($ButtonLabel);
//determine label upper left corner
$ButtonLabelX = ($ButtonWidth - $ButtonLabelWidth)/2;
$ButtonLabelY = ($ButtonHeight - $ButtonLabelHeight)/2;
//draw label shadow
imagestring($image, $ButtonFont, $ButtonLabelX+1, $ButtonLabelY+1, $ButtonLabel, $colorShadow);
//draw label
imagestring($image, $ButtonFont, $ButtonLabelX, $ButtonLabelY, $ButtonLabel, $colorHighlight);
//output image
header("Content-type: image/png");
imagepng($image);
?> |
So, if not making a image, then what is it doing? |

You should install the php_gd.dll and/or php_gd2.dll as extensions to PHP to allow image creation. These two extensions aren't packaged with the small PHP distribution. You should rather download the 5MB PHP package at http://www.php.net/get_download.php?df=php-4.2.3-Win32.zip and install it in order to have these extensions (and a lot more) by default.
