Hi there,
I would like to create a new pattern. This pattern would be a very small text repeated over and over to fill a node. Something that would actually be like a watermark equivalent to very small text on money bills…
I tried the following code : 

\pgfdeclarepatternformonly{filli}% 
{\pgfpointorigin}% 
{\pgfqpoint{0cm}{0cm}} 
{\pgfqpoint{\textwidth}{1cm}} 
{\pgftext{\fontsize{5}{0}\selectfont 0x41 0x76 0x71 0x65 0x75 0x48 0x62 0x6E 0x63 0x65}\pgfusepath{fill}}

It does not work at all…

Thanks in advance for your help…
