reading this, I tried it out on my Leopard machine, with Keynote 3 (I
have Keynote 4 on a Tiger machine that I use predominantly). And of
course, as Martin said, the copying from Preview is totally messed up.
But I figured out a way to fix it, using ghostscript. Here is a
python script that has to be invoked ater you copied a selection in
Preview. When the script is done, the clipboard will contain a
"fixed" version of the copied selection. Now just switch to Keynote
and paste from the clipboard, and you get only the desired cropped
I didn't have time to put in the extra fluff to make a temp file and
delete it again when the script is done, and of course I should wrap
this up as an "Application" for Terminal-averse users. Also, it
doesn't perform any error handling. I'll probably add this if someone
lets me know that it works with Keynote 4 on Leopard. I only tested
it with Keynote 3 on Leopard, as mentioned above. It's just the proof
Here's the code:
Save this script as "clipPDF" somewhere in your PATH, and run it in
the Terminal with "clipPDF" everytime you have copied a PDF
selection to the clipboard. I'm using fink's python and PyObjC for
this script - knowing that at least Martin is likely to have that
installed. It would be easy to translate this back into Cocoa as
well, but python is just so much faster to write.
