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.


= new ImagickDraw();


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