[magick-users] Draw test variables fails

[Adam Dershowitz]

I am trying to add displayed page number to a pdf.  The problem is  
that the draw command is not expanding the variables.  I am not sure  
what I am doing wrong.  I am ending up with the literal "%p" rather  
than the actual page number.  I have tried a few different things like  
this:

convert testin.pdf -draw 'text 100,100 "%p"'  testout.pdf

If I do it this way: convert testin.pdf -draw 'text 100,100 %p'   
testout.pdf
then I get an error:  convert: Non-conforming drawing primitive  
definition `p'.
and my image just has a literal %.

Just to make sure that it was not an issue with gs and pdfs I also  
tried a few tests with jpgs and got the same results.

I do know that montage is correctly adding labels so things like this  
do work:
montage -label "%f" *.jpg output.jpg

What am I doing wrong?  How can I add page number to a pdf?

I am using ImageMagick 6.4.2-7 on a Mac, and using the Bash shell.

Thanks much.
