prawn - import image from URL

Question

I can't seem to figure out how to import an image from an url

To import the images from my localhost I use:

image"./assets/images/img.png"

When I replace the path with an URL it says

`image' : URL not found

Is there a solution for this, or should I create a def that downloads the image and to use the path it returns?

Answer 1

you need to do the following -

require "open-uri"

Prawn::Document.generate(INSERT_YOUR_PDF_FILENAME_HERE) do 
   image open(INSERT_YOUR_URL_HERE)
end

Refer to http://rubydoc.info/gems/prawn/0.12.0/frames for more details.

Thx, but I found that same solution later that day :-). I forgot to post it here. Thank you anyway! If I would not have found it on my own, this would have fixed the problem for me! – Worser

Good that your problem has been resolved and I think it would be nice if you accept or uptick this answer! – Roundhead

How can I use this if I have a file.pdf.rb because i think that code is for the controller ?? – Fredericton

Could someone tell me how to use this in github.com/spree-contrib/spree_print_invoice/blob/master/app/… on line 8? I cant seem to get it to work. – Phagocytosis

I got this working for me:

image open("https://driver.mbpgroup.eu/images/mbp_logo.jpg"), position: :right, width: 250

I could NOT get this to work for me (Prawn documentation):

image "https://driver.mbpgroup.eu/images/mbp_logo.jpg", position: :right, width: 250
