note 78399 added to function.imagecolorallocate

hex2color once again: this is the simplest possible method


<?php

$htmlcolor = "FF9900";
$color = hexdec ($htmlcolor);

?>

Let's face the truth: for the truecolor images,
imagecolorallocate doesn't allocate anything, but simply
makes a hex representation of color, treats it as one large
hex number, and calculates an int value from it.

Oh, it's probably a good idea to validate $htmlcolor first,
like:

<?php

if (!eregi('^[0-9a-f]$', $htmlcolor)) die ("bad
color");

?>
