It will also check and make sure that it's a valid 6 digit hex value after the stripping of non-hex characters takes place. it simply uses the function hexdec() to convert each R, G, and B hex values to decimal, and then passes them to imagecolorallocate() individually. See the page: http://us3.php.net/imagecolorallocate to learn how to use this wrapper function.</p> Tue, 09 Sep 2008 13:55:48 UTC https://snipplr.com/view/8273/imgcolorallocate-wrapper-that-allows-hex-values-instead-of-rgb
