CF Image IP changing opacity and/or default size - php

Question

I'm using this image ip generator from codefuture, which is giving me an image with the IP adresse.
I would like to change the Opacity and the default size of it as I'm using it as a watermark over a video. So I can't use css nore html or javascript resize and opacity.
Here is the PHP code:
// Image color setup
$outerBorder = "000000"; // ob=b9b9b9
$innerBorder = "000000"; // ib=ffffff
$leftFill = "ffffff"; // lf=cccccc
$leftTextColor = "000000"; // ltc=555555
$rightFill = "000000"; // rf=dddddd
$rightTextColor = "ffffff"; // rtc=555555
// on-the-fly color settings
// <img src="ip.php?ob=b9b9b9&ib=ffffff&lf=cccccc&ltc=555555&rf=dddddd&rtc=555555" />
// image quality from 0-100
$scaleQuality = 80;
////////////////////////////////////////////////////////////////////////////////////

// Do not edit beyond this line
// get on-the-fly color settings
if(isset($_GET['ob'])) $outerBorder = $_GET['ob'];
if(isset($_GET['ib'])) $innerBorder = $_GET['ib'];
if(isset($_GET['lf'])) $leftFill = $_GET['lf'];
if(isset($_GET['ltc'])) $leftTextColor = $_GET['lt'];
if(isset($_GET['rf'])) $rightFill = $_GET['rf'];
if(isset($_GET['rtc'])) $rightTextColor = $_GET['rt'];
// draw the image
DrawButton($outerBorder,$innerBorder,$leftFill,$leftTextColor,$rightFill,$rightTextColor,$scaleQuality);

Thanks in advance for helping me with this.
