If you want to fill an image with a "hexadecimal color" use this function:
<?php
function hextodec($hex){
$hex=split('#', $hex);
$hex=end($hex);
$dec=array(
"r"=>hexdec(substr($hex, 0, 2)),
"g"=>hexdec(substr($hex, 2, 2)),
"b"=>hexdec(substr($hex, 4, 2))
);
return $dec;
}
//Use this function:
$color=hextodec("#5522ff");
$bgcol=imagecolorallocate($img, $color[r], $color[b], $color[b]);
header("Content-type: image/jpeg");
$img=Imagecreate(100, 100);
imagefill($img, 1, 1, $bgcol);
imagejpeg($img, 'test.jpg', 100);
imagedestroy($img);
?>
