imagefontwidth() error

[Anon]

I get this message error when I am trying to read that php:
X-Powered-By: PHP/4.0.1pl2 Content-type: text/html
Fatal error: Call to undefined function: imagefontwidth() in d:\www\test\button\button.php on line 27

This is the php:

define("TextFONT", "3");

function ConvertColor($hexVal){
$ColorVal = array(3);
for($i = 0; $i < 3; $i++)
$ColorVal[$i] = HexDec(substr($hexVal, $i * 2, 2));
return $ColorVal;
}

$width = strlen($txt) * ImageFontWidth(TextFONT);
$offset = 2;
$imgFRAME = ImageCreate($width, ImageFontHeight(TextFONT)+$offset);

list($red, $green, $blue) = ConvertColor($bg);
$bgCOLOR = ImageColorAllocate($imgFRAME, $red, $green, $blue);

list($red, $green, $blue) = ConvertColor($fg);
$fgCOLOR = ImageColorAllocate($imgFRAME, $red, $green, $blue);

ImageFill($imgFRAME, 1, 1, $bgCOLOR);
ImageString($imgFRAME, TextFONT, 1, 1, $txt, $fgCOLOR);

header("Content-type: image/gif");
ImageGIF($imgFRAME);
ImageDestroy($imgFRAME);

Can anyone help??

ImageFontWidth() does take a "int" as it's parameter, but that integer is actually a pointer set to a particular font resource, not a numeric value as you have it defined in a constant.

My guess is that you first need to set $TextFONT to some font resource, such as:

$TextFONT = "/usr/local/fonts/comic.ttf";

and then pass it as the parameter to ImageFontWidth($TextFONT).

At least this is the only way I have gotten it to work.
