Hi Wolfgang,
How to reduce the size of the float ?
Best regards,
Fabrice

\usemodule[algorithmic]
\definefloat[algorithm][algorithms]

\definecolor[H1prime][c=0.50, m=0.00, y=1.00, k=0.00]
\definecolor[H4][c=0.07, m=0.00, y=0.15, k=0.00]

\setupfloat
[algorithm]
[background=color,
   frame=on,
   framecolor=H1prime,
   backgroundcolor=H4,
   width=0.5\textwidth]

You have to put a framedtext environment around the algorithmic environment, you can do this by replacing \setupfloat with \setupalgorithmic.

\setupalgorithmic

[algorithmic]

[before={\startframedtext[width=0.6\textwidth,background=color,backgroundcolor=H4,framecolor=H1prime]},

after={\stopframedtext}]
