some questions about logo and margin background.

[lihb <lihb@phys.sinica.edu.tw>]

Hi,
  I have two question, I 'm not sure this is the right place to ask,
apologize for that.

   1st question: I wish to put a small logo at the footer at everypage
so I try to write a tex as below:

\usemodule[pre-general]

\setuppapersize
  [S6][S6]

\setuplayout
  [width=fit,
   height=fit,
   header=32pt,
   footer=32pt]

\setupfootertexts[\bf\ss{test}][\bf\ss{\date}]

\def\RedHatLogo%
  {\externalfigure[shadowman-32.png][type=png]}

\definelogo
  [small logo] [footer] [middle]
  [command=\RedHatLogo,state=start]

\starttext
\chapter{test}

\placelogos[small logo]

\stoptext

and I found that the shadowman logo did not show up..
How do I make a .png file show up at corner or bottom of every pages?

   2nd question: change the background of margin
I have a rightmargin with

\startuniqueMPgraphic{test}
  picture p ; p := btex TEST etex rotated 90 ;
  setbounds p to boundingbox p enlarged 1pt ;
  draw p withcolor 0.8white ;
  currentpicture := currentpicture
      xysized (\overlaywidth,\overlayheight) ;
\stopuniqueMPgraphic
\defineoverlay[test][\uniqueMPgraphic{test}]

\setupbackgrounds
  [text]
  [rightmargin]
  [background=test]

which is a word "TEST" with grey color and white background,
how to change the background color?
I had try 'fill p withcolor darkcyan ;'
but the background of margin is still white.

Thanks.
