[texhax] Set dimension for picture environment

[hh-brasil at bol.com.br]

How about at the very beginning of the picture or for the whole document

\psset{xunit=\textwidth, yunit=\textheigt}
or 
\psset{xunit=\textwidth, yunit=1.4\textwidth, runit=\textwidth}

Do you need \runit for radius etc? Then define it.


Then you use only numbers as you would normally do!

Dear all,
I would like to create a picture in normalized unit so that everything is
expressed by values between 0 and 1.
The box would take the entire page (ie \textwidth, \textheight). I set
\setlength{\unitlength}{\textwidth}. Unfortunately, this gives a
noramlisation with x-coordinate but not with y-coordinate. So I want to
create a command \yscale that allows to do a scaling:
\put(0.5, \yscale{0.5}) or \put(0.5, 0.5\yscale)

What should I set into \yscale ?

I don't know how to make latex considering that the results of \yscale{0.5}
is a number.
