[comp.text] reverse letter?

wshi@s.cs.uiuc.edu (04/13/89)

Could somebody tell me how to print a letter backwards using troff?
I mean, for example, to print letter "R" this way:


		  oooooo
		o      o
		o      o
		  oooooo
		   o   o
		  o    o
		 o     o
		o      o


Thanks in advance.

That is not a function of troff (or any other text formatter);
you either need a font on your output device which contains reversed
images, or have a DEVICE function to reverse the image, in which case
you could use troff's transparent output function, \!, to send
the appropriate control sequence to your device, and then to turn
it off again.
