Christian wrote once into c.l.t.:

[BLT] can create (semi-transparent) bitmaps of text in arbitrary directions.

Try the following:
----
     package require BLT
     ::blt::bitmap compose myNewBitmap "this is a text" \
	 -font "Arial 10 bold" \
	 -rotate 90 \
	 -justify left
     $myCanvas create bitmap 50 50 -bitmap myNewBitmap \
	 -foreground blue \
	 -anchor nw \
	 ...
----

This works nicely.
----
[RS]: Shouldn't the font rather be called Arial (or Helvetica, for even more platform-independence)?

----
It's nice on the screen, but less nice on postscript output. 
Ability to rotate any standard canvas object would be a nice upgrade to Tk.

[RS]: see [photo image rotation] and [canvas rotation] (for lines and polygons)
----
But blt-bitmaps cannot be destroyed, so the memory will be full of bitmaps when using this way too often.

----
See [Rotated canvas text] for how some X servers can do this with pure Tk

[KBK] 2008-11-03 Or look at http://wiki.tcl.tk/_repo/hershey/ for a way to do it in pure Tcl/Tk with only line drawing.

[Lars H], 2008-11-03: That directory appears to be empty. But what kind of fontsize would this allow? Probably not anything near the 10 shown above, since [XLEL] limits Tk to pixel precision.

[Lars H], 2008-11-04: OK, the [Half Bakery] contents appears to be back. And answering my own question: the font size used by the demo program appears to be 33.


[lm] 2008-11-04 : Notice that the pixane package from evolane (www.evolane.com -> Projects -> pixane) is an extension that allow to create bitmap/photo images rotated. It's available for almost all platforms.
