Creating a PDF on the fly

Rails
1

A friend and I are just in the process of trying to create PDFs on the
fly. This isn’t in itself too hard, but we have some repeating images
that are being put in over and over again. It’s increasing file size
too much unfortunately.

Does anyone know the best way to ensure file size is kept to a minimum
for this scenario? We know about linking to a URI, but the problem with
that is that if the PDF gets sent elsewhere, we have to send the linked
images with it.

Any help would be appreciated.

Thanks

If you’re using PDF::Writer, then it’s trivial to reuse images that
are repeating. You just have to do it right (and the demo
chunkbacon.rb shows how).

If you’re not using PDF::Writer, then you need to be more specific
about your problem.

That’s helpful thanks. I hadn’t found the “demo” section because I was
looking for “examples” :slight_smile: I have actually looked at the gem code to
figure out how to load the image only once. Figured it out now, so
thanks. Really helpful.
