Hello Barry and Shane,

Thank you very much for the two scripts. I don't own PDFPen, but I have Adobe Acrobat and PDF Clerk Pro. The script by Barry worked just fine with the both applications. I didn't know that Acrobat was so much scriptable.

In both applications, the script works very quickly, though Acrobat seems a little speedier than PDF Clerk Pro. What is slow is the process to save the result. Moreover, PED Clerk Pro, at least, creates a huge file (what was 30 MB becomes something like 2 GB). When I reduce the file size with Acrobat, it returns to a normal size file -- but the process of reducing the file is VERY slow...

I would like to try Shane's script, but I am still on Mountain Lion, so I will go to Marvericks to try it.

Anyway, thank you so much again.

Best regard,

Nobumi Iyanaga
