90° rotation + landscape

[Peter Rolf <peter.rolf@arcor.de>]

Hello list,

I want to setup an evelope and the whole output should be rotated by 90°
(this is the way my printer gets them).
                ___
               |  ||
________       |   |
| --     |     |   |
|_____--_|     ||__|

normal layout   90° rotated output (paper and content)

The resulting pdf looks like this (square paper format):
 ______
|  |   |
|      |
|      |
||_____|


Here is a minimal example:


% interface=en output=pdftex
\definepapersize[C65] % standard C65 evelope
 [width=229mm,
  height=114mm,
 ]

\setuppapersize[C65][C65, landscape, 90]

\starttext
\tfc 90° rotation for printer.
\stoptext


Have I missed something or is this a bug in \dodosetuppapersize?
Any help welcome,

 Peter
