Thank you so much for your help!
I am finally able to install pdftk. I have a question about how to send
pdf to browser directly.
my code is here:
pdf_output = `pdftk #{filename} fill_form #{fdf.path} output`
respond_to do |format|
format.pdf do
send_data pdf_output, :filename => filename,
:type => "application/pdf"
end
end
But the browser can not open the pdf. It says it is empty.
What is the correct way to do this?
