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.
