[magick-users] Draw test variables fails

[Fred Weinhaus]

Unfortunately, I don't think IM will parse the %p directly into 
-draw. You need to store that in a shell variable. But I don't know 
that IM will know what page you have in the pdf. I don't work with 
them often.

For example try:

page=`convert testin.pdf -format "%p" info:`
convert testin.pdf -draw 'text 100,100 $page'  testout.pdf

This might work in one step:
convert testin.pdf -draw 'text 100,100 $(convert testin.pdf -format 
"%p" info:)  testout.pdf


Try it with %t rather than %p to see if it recognizes the top of the 
file name, if it does not work because IM cannot figure out the page 
number in the pdf.
