I'm not sure this is possible, but maybe someone has a smart idea. I've got a pdf that users are printing off our website which is used as a registration card. What I'd like to be able to do is insert a barcode onto that pdf when it's viewed/printed, plus add that barcode to their user record.
I have a custom tag I downloaded somewhere which allows me to create barcodes in .gif or .jpg format, which has been very useful. But...how to embed that into a pdf? Anyone think it's possible? I've played some with CFIMAGE for other things, but I can't see a way to use that tag to do this.
Why would you use an image? Why not just use straight text using a barcode font?
Did you try an <img> tag?
