When wishing to print some text on a photograph and make that text sufficiently contrasting to the background image, use a 4 byte code for colour and transparency.

It is the same 4 byte code using by the parameter '-undercolor' in ImageMagick's command lime instruction 'convert'.

The first 3 bytes are the RGB colour code and the fourth byte is the transparency byte.

<?php

$draw
= new ImagickDraw();
$draw->setFillColor('#ffff00');
$draw->setFont('Eurostile');
$draw->setFontSize(21);
$draw->setTextUnderColor('#ff000088');
$picin->annotateImage($draw,40,$height-10,0,"Hallo");

?>

The example code produces yellow text on a semi-transparent red background.
